Jesus' Advice on Fasting

 

In the heart of Jesus' Sermon on the Mount, nestled within a discourse on righteous living, we find a profound teaching on fasting. This practice, often overlooked in modern Christian circles, is presented not as an optional spiritual exercise but as an assumed discipline for followers of Christ. Drawing from the English Standard Version (ESV) of the Bible, let's examine Matthew 6:16-18:

"And when you fast, do not look gloomy like the hypocrites, for they disfigure their faces that they may appear to men to be fasting. Truly, I say to you, they have received their reward. But when you fast, anoint your head and wash your face, that your fasting may not be seen by others but by your Father who is in secret. And your Father who sees in secret will reward you."

This passage invites us into a deeper understanding of spiritual devotion, challenging us to move beyond outward displays and into the intimate realm of communion with God. As we exegete this text, we'll delve into key Greek words and phrases from the original language, uncovering their nuances and implications. We'll explore historical context, theological depths, practical applications, and even potential pitfalls, all while considering how this ancient wisdom speaks to our contemporary lives. Fasting, as Jesus teaches it, is not merely about abstaining from food but about cultivating a heart attuned to the divine, a "soul-fattening" discipline that nourishes our inner being even as our bodies hunger.

To set the stage, consider the broader context of the Sermon on the Mount (Matthew 5-7). Jesus is redefining righteousness for His kingdom, contrasting it with the religious elite's superficial piety. In Matthew 6:1-18, He addresses three pillars of Jewish devotion: almsgiving (vv. 1-4), prayer (vv. 5-15), and fasting (vv. 16-18). Each section follows a similar structure: a warning against hypocritical practice, a description of its reward (limited to human praise), and instructions for authentic observance, culminating in the promise of divine reward. This pattern underscores a central theme: true righteousness is motivated by love for God, not acclaim from others.

Fasting, in Biblical terms, involves voluntary abstinence from food (and sometimes water) for a spiritual purpose. It is not dieting or a health regimen, though physical benefits may accrue incidentally. The Greek term for fasting, νηστεύω (from νῆστις, meaning "not eating"), appears repeatedly in this passage, emphasizing the act's intentionality. In verse 16, Ὅταν δὲ νηστεύητε ("And when you fast") uses the conjunction ὅταν, which implies "whenever" or "as often as," assuming the practice as a regular part of the disciple's life rather than a hypothetical "if." This subtle linguistic choice, ὅταν rather than ἐάν, signals expectation rather than optionality. Jesus doesn't command fasting here but presupposes it, much like giving and praying. As one commentator notes, this assumption reflects the cultural and religious milieu in which fasting was commonplace yet often corrupted.

Historically, fasting held deep roots in Jewish tradition. The Old Testament mandated it on the Day of Atonement (Leviticus 16:29-31; 23:27-32), a day of national repentance and of the soul's affliction. During the Babylonian exile, additional fasts emerged to commemorate tragedies such as the temple's destruction (Zechariah 7:3-5; 8:19). By Jesus' time, pious Jews, especially Pharisees, fasted twice weekly, typically on Mondays and Thursdays, days associated with Moses' ascent and descent from Sinai. These fasts could be public or private, but as Jesus critiques, they often devolved into spectacles of self-promotion. The Mishnah and other rabbinic texts describe elaborate rituals, including ashes on the head to signify mourning, which amplified visibility.

From a theological angle, fasting symbolizes humility, dependence on God, and mourning over sin. It intensifies prayer, sharpens spiritual focus, and expresses solidarity in times of crisis. In the New Testament, Jesus fasted for forty days in the wilderness (Matthew 4:1-11), modeling reliance on God's Word rather than physical sustenance. His disciples fasted after His ascension (Acts 13:2-3; 14:23), using it for discernment and commissioning. Yet, Jesus' teaching here pivots on motive: Is fasting for God's eyes or human applause? This question probes the heart, echoing Proverbs 21:2: "Every way of a man is right in his own eyes, but the Lord weighs the heart."

Now, let's turn to a verse-by-verse exegesis, focusing on key Greek terms and their explanations. We'll unpack the language, draw from historical insights, and explore multifaceted implications, theological, psychological, ethical, and practical, while addressing edge cases like cultural adaptations or health considerations.

Exegesis of Verse 16: The Hypocrisy of Showy Fasting

"And when you fast, do not look gloomy like the hypocrites, for they disfigure their faces that they may appear to men to be fasting. Truly, I say to you, they have received their reward."

The verse opens with Ὅταν δὲ νηστεύητε, as noted, assuming fasting's regularity. The imperative μὴ γίνεσθε ("do not become" or "do not be") is a present middle/passive, urging a cessation of ongoing behavior, don't adopt the gloomy demeanor as a habit. The word σκυθρωποί ("gloomy" or "sad-faced") conjures images of sullen expressions, perhaps exaggerated sighs or downcast eyes, meant to convey suffering.

Jesus contrasts this with οἱ ὑποκριταὶ ("the hypocrites"). The term ὑποκριτής originally meant "actor" in Greek theater, referring to one who plays a role under a mask. By Jesus' era, it connoted religious pretenders, those whose piety is performative, not genuine. Pharisees and scribes often fit this description, using fasting to bolster their reputation for holiness (Luke 18:12). Psychologically, this reveals a human tendency toward virtue signaling: We crave affirmation, and spiritual acts become tools for social capital. Theologically, it warns against idolatry, worshiping human approval over God (Galatians 1:10).

The phrase ἀφανίζουσιν γὰρ τὰ πρόσωπα αὐτῶν ("for they disfigure their faces") is intriguing. The verb ἀφανίζω means "to make unseen" or "to render unattractive," from ἀ- (negative) and φαίνω ("to shine" or "appear"). In context, it suggests neglecting grooming, unwashed faces, unkempt hair, perhaps smeared with ash, to look haggard and devout. Commentators debate the exact practice: some see it as "hiding" the face in mourning garb, while others see it as deliberate disfigurement to evoke pity. A Greek lexicon entry highlights its use in later texts for "deforming" or "spoiling" appearance, aligning with the contrast in verse 17. This act inverts the true purpose of fasting: Instead of humbling oneself before God, it elevates the self before others.

The purpose clause ὅπως φανῶσιν τοῖς ἀνθρώποις νηστεύοντες ("that they may appear to men to be fasting") employs φανῶσιν, a subjunctive from φαίνω, emphasizing visibility. It's a wordplay: They "disfigure" (ἀφανίζω) to "appear" (φαίνω), hiding true motives to shine in false light. This underscores irony: Hypocrites seek temporal glory, missing eternal communion.

Jesus seals the warning with ἀμὴν λέγω ὑμῖν, ἀπέχουσιν τὸν μισθὸν αὐτῶν ("Truly, I say to you, they have received their reward"). Μισθός means "wage" or "recompense," like payment for labor. The present tense ἀπέχουσιν implies full settlement; they've cashed their check in human praise; no divine bonus awaits. Theologically, this echoes the principle of sowing and reaping (Galatians 6:7-9): Motives determine rewards. Practically, it challenges us: Are our devotions Instagram-worthy performances or hidden treasures?

Nuances here include cultural variations. In first-century Judaism, public fasts (e.g., for rain or calamity) were communal, yet Jesus targets private ones twisted for show. Edge cases: What if fasting is corporate, like in Lent? The principle holds: avoid ostentation. Health-wise, those with medical conditions (diabetes, pregnancy) might adapt with partial fasts, focusing on intent over form. Psychologically, showy fasting can foster pride or eating disorders; true fasting promotes self-awareness and empathy for the hungry.

From multiple angles, this verse critiques legalism: Pharisees expanded the OT fasts, but Jesus restores heart focus. Historically, Church Fathers like Augustine saw fasting as taming the flesh; modern applications include fasting from media to achieve spiritual clarity. Implications: In a social media age, "virtue posting" mirrors hypocrisy; sharing fasts for likes risks forfeiting heavenly reward.

Exegesis of Verse 17: The Practice of Secretive Fasting

"But when you fast, anoint your head and wash your face,"

The adversative σὺ δὲ ("But you") shifts to positive instruction, emphasizing contrast. Νηστεύων ("when you fast," a present participle) reinforces the assumption. The commands ἄλειψαι τὴν κεφαλὴν σου καὶ τὸ πρόσωπόν σου νίψαι ("anoint your head and wash your face") are aorist imperatives, suggesting decisive, punctual actions.

Ἀλείφω ("anoint") typically involved olive oil for hair or skin, a daily Jewish custom for refreshment and hygiene (Ruth 3:3; 2 Samuel 12:20). In a hot, dusty climate, it helped prevent dryness and signified normalcy. Νίψαι, from νίπτω ("wash"), refers to cleansing the face, perhaps with water, or routine grooming. Together, they instruct: Maintain appearance; don't advertise the fast.

Theologically, this promotes authenticity: Fasting is vertical (Godward), not horizontal (manward). Psychologically, it counters performative religion, fostering intrinsic motivation. Practically, it liberates, no need for theatrics; just faithfulness. Cultural nuance: In the Greco-Roman world, anointing symbolized joy (Psalm 23:5); during fasts, it defied gloom, aligning with kingdom values of inner peace.

Edge cases: For women in modest cultures, "anointing" might take on different forms; for all, it's about inconspicuousness. Implications: In busy lives, secret fasting builds discipline without disrupting daily routines. Historically, Puritans called it "soul-fattening," as abstaining heightens spiritual hunger (Psalm 42:1-2).

Exegesis of Verse 18: The Promise of Divine Reward

"that your fasting may not be seen by others but by your Father who is in secret. And your Father who sees in secret will reward you."

The purpose clause ὅπως μὴ φανῇς τοῖς ἀνθρώποις νηστεύων ἀλλὰ τῷ πατρί σου τῷ ἐν τῷ κρυπτῷ ("that your fasting may not be seen by others but by your Father who is in secret") uses φανῇς (subjunctive of φαίνω), echoing verse 16's irony, avoid appearing to men. Κρυπτῷ ("secret" or "hidden," from κρυπτός) denotes the unseen realm, twice repeated for emphasis.

Τῷ πατρί σου ("your Father") personalizes God, evoking intimacy (Abba). Ὁ βλέπων ἐν τῷ κρυπτῷ ("who sees in secret," present participle βλέπων from βλέπω) highlights omniscience; God perceives hearts (1 Samuel 16:7). Ἀποδώσει σοι ("will reward you," future indicative from ἀποδίδωμι, "give back") promises recompense, not earned but graciously given.

Theologically, this assures God's attentiveness: Secret acts yield open rewards (perhaps spiritual growth, answered prayer, eternal glory). Psychologically, it motivates through relational trust. Practically, rewards vary, clarity, breakthrough, and character. Edge cases: If fasting leads to unintended visibility (e.g., weight loss), intent matters. Implications: In secular societies, secret fasting counters consumerism, fostering contentment.

Fasting in Modern Life

In light of this exegesis, fasting emerges as a tool for spiritual vitality. Benefits: Deepens prayer, breaks addictions, heightens gratitude. Nuances: Duration varies (one meal to forty days); include Scripture meditation. Warnings: Avoid extremes, Jesus critiques hypocrisy, not fasting itself. Corporate fasts (Joel 2:15-17) build community if heartfelt.

Multiple angles: Theologically, it mirrors crucifixion, dying to self (Galatians 2:20). Psychologically, it builds resilience. Ethically, pair with justice (Isaiah 58:6-7), fast to feed others. Culturally, adapt for non-food fasts (technology). Edge cases: Mental health, consult professionals; interfaith contexts, respect differences.

In conclusion, Matthew 6:16-18 calls us to hidden holiness, where fasting fattens the soul in God's secret presence. As Spurgeon quipped, it might profit us more under the Gospel. May we fast not for show, but for the Father's reward, transforming hunger into heavenly feast.

New Wine in New Wineskins

 

It began with a simple, sincere question. The disciples of John the Baptist approached Jesus and asked, "Why do we and the Pharisees fast, but your disciples do not fast?" (Matthew 9:14, ESV). This was not a hostile interrogation. John's followers were genuinely puzzled. Fasting was woven into the fabric of Jewish piety; it marked seasons of repentance, mourning, and earnest prayer. Why would the disciples of the long-awaited Messiah abandon such a practice?

Jesus' answer was astonishing. Rather than defending a schedule or explaining a loophole in the fasting laws, He told a story about a wedding banquet, and then He pivoted to two earthy parables about cloth and wine that carried the weight of an entire theological revolution. These parables, recorded in Matthew 9:14–17, Mark 2:18–22, and Luke 5:33–39, are not merely clever illustrations. They are Jesus' own announcement that something so fundamentally new had broken into human history that the old containers, the old ways of relating to God, could no longer hold it.

To understand these parables deeply, we must do more than read the English. We must enter the original Greek language in which the New Testament was written, where several key words carry freight that our translations can only partially convey.

The Bridegroom is Here: A Season Unprecedented

Before Jesus introduced the wineskin imagery, He responded to the question about fasting with a question of His own: "Can the wedding guests mourn as long as the bridegroom is with them?" (Matthew 9:15a, ESV). The phrase "wedding guests" translates the Greek οἱ υἱοὶ τοῦ νυμφῶνος, literally, "the sons of the wedding chamber." This was a Hebrew idiom for the closest companions of the bridegroom, the inner circle who shared in every joy of the celebration.

The word for "bridegroom" is νυμφίος (numphios), a word loaded with Old Testament resonance. The prophets had described God Himself as the bridegroom of Israel (Isaiah 62:5; Hosea 2:16). John the Baptist had already used this imagery, calling himself "the friend of the bridegroom" who rejoices to hear the bridegroom's voice (John 3:29). Now Jesus applied the title to Himself. He was not merely a prophet or a teacher, He was the divine Bridegroom who had arrived at His own wedding feast.

This is why mourning and fasting were incompatible with the present moment. The Greek verb πενθεῖν (penthein), translated "mourn" in the ESV, is used elsewhere in the New Testament for grief over death and loss (Revelation 18:11; 1 Corinthians 5:2). To fast and mourn while the Bridegroom was physically present among His disciples would be as absurd as weeping at a wedding while the groom stands at the altar. The time for fasting would come, Jesus alluded to His coming crucifixion in the phrase "when the bridegroom is taken away from them", but that hour had not yet arrived.

"Can the wedding guests mourn as long as the bridegroom is with them? The days will come when the bridegroom is taken away from them, and then they will fast.", Matthew 9:15, ESV

The Torn Garment: When Old and New Cannot Mix

Immediately following this exchange, Jesus offered the first of two parables: "No one puts a piece of unshrunk cloth on an old garment, for the patch tears away from the garment, and a worse tear is made" (Matthew 9:16, ESV). The phrase "unshrunk cloth" translates ῥάκους ἀγνάφου, cloth that is ἄγναφος (agnaphos), meaning "uncarded" or "unprocessed." In the ancient world, new fabric would shrink significantly during the first wash. Sewing a patch of raw, uncarded cloth onto an old, pre-shrunk garment would be a disaster: when washed, the new patch would contract and pull violently at the aged fabric, turning a small tear into a catastrophic rip.

Luke's version adds a poignant detail. He notes that the piece is taken ἀπὸ ἱματίου καινοῦ, "from a new garment." You don't just ruin the old garment; you ruin the new one too. You cut a piece from something beautiful and whole, only to destroy both. The word καινός (kainos) appears here and throughout the wineskin parable, and it deserves careful attention. In Greek, two words are often translated "new": νέος (neos), which means new in the sense of being recent or young in age, and καινός, which means new in the sense of being of a different kind, unprecedented in quality or nature. When Jesus describes the new wine and new wineskins, He consistently uses καινός, not merely something recently made, but something qualitatively different, something that represents a new order of reality altogether.

This distinction is vital. The New Covenant Jesus was inaugurating was not a recent update to an aging system. It was a different kind of covenant, unprecedented, superior, and incompatible with the structures that preceded it.

The Wineskins: Why the Old Cannot Contain the New

The Parable Across Three Gospels

"And no one puts new wine into old wineskins. If he does, the wine will burst the skins, and the wine is destroyed, and so are the skins. But new wine is for fresh wineskins.", Mark 2:22, ESV

"And no one puts new wine into old wineskins. If he does, the new wine will burst the skins and it will be spilled, and the skins will be destroyed. But new wine must be put into fresh wineskins.", Luke 5:37–38, ESV

All three synoptic Gospels preserve this parable, each with slightly different nuances. The cultural backdrop would have been immediately legible to Jesus' audience. In first-century Palestine, wine was stored and transported in pouches made from animal skins, typically goat, sewn together and sealed to be airtight. A new wineskin had supple, elastic leather that could expand as the fermenting wine released διοξείδιο τοῦ ἄνθρακος (carbon dioxide) during fermentation. An old wineskin, however, had already been stretched to its limit by a previous batch of wine. The leather had dried, hardened, and lost its elasticity. Pour new, still-fermenting wine into such a container, and as the fermentation gases built up pressure, the rigid old skin could not flex. It would crack, then burst, destroying both the wine and the wineskin.

Key Words: Old and New

In Mark 2:22, Jesus contrasts ἀσκοὺς παλαιούς ("old wineskins") with ἀσκοὺς καινούς ("new wineskins"). The word παλαιός (palaios) means old in the sense of worn out, outworn by time, no longer adequate to its purpose, not simply ancient, but rendered obsolete. This is exactly the word used in Hebrews 8:13 when the writer declares that in speaking of a new covenant, God has made the first one παλαιός: "And what is becoming obsolete and growing old is ready to vanish away." The Old Covenant, with all its sacrificial system, ceremonial washings, and annual fasts, had served its purpose, but it was παλαιός. It could not contain what God was now doing in Christ.

Mark 2:22 contains another striking word. In describing what happens when new wine is put into old skins, he uses ῥήγνυσιν, the verb ῥήγνυμι (rhegnumi), meaning "to burst" or "to tear violently." This is not a slow leak or a gentle seepage. It is a catastrophic rupture. The image is visceral and urgent: the mismatch between new and old is not a minor inconvenience to be managed, it is a crisis that, left unaddressed, results in total destruction.

Luke adds a phrase found in neither Matthew nor Mark: οἶνον νέον εἰς ἀσκοὺς καινούς βλητέον, "new wine must be put into fresh wineskins." The word βλητέον is a verbal adjective indicating necessity, obligation, what is required. The pairing of νέος and καινός in Luke's formulation, the wine is νέος (newly made, freshly pressed) and the skins are καινός (qualitatively new, of a new kind), captures both the immediacy and the qualitative transformation that the Gospel demands.

What Was the "Old Wineskin"?

We must ask the exegetical question: what, exactly, did the old wineskin represent in Jesus' teaching? John's disciples were practicing fasting according to the traditions of Second Temple Judaism. The law prescribed fasting on the Day of Atonement (Leviticus 16:29–31), and additional fasting practices had been layered on over the centuries (Luke 18:12). These rituals were not sinful; they were sincere expressions of devotion within the Old Covenant framework that God Himself had established.

But the Old Covenant was always meant to be preparatory, not permanent. The book of Hebrews develops this extensively: the sacrifices were a σκιά, a shadow, of the good things to come (Hebrews 10:1). The Greek word σκιά (skia) evokes a shadow cast by a solid object. The substance, the σῶμα, the body, belonged to Christ (Colossians 2:17). The law was not the reality; it pointed forward to the reality. The old wineskin was structurally incapable of containing the new wine, not because the old wineskin was evil, but because it had been stretched to its limit. It had done its work. Now something fundamentally different was required.

Jesus was not founding a reform movement within Judaism. He was not suggesting that a few modifications to the Pharisaic system would suffice. He was inaugurating a καινὴ διαθήκη, a new covenant, as He would later declare at the Last Supper: "This cup that is poured out for you is the new covenant in my blood" (Luke 22:20, ESV). The word διαθήκη (diatheke) means covenant or testament, a binding agreement established by one party on behalf of another. This was not an amendment to the old agreement. It was a new one, established in the blood of the Son of God, fulfilling and superseding everything that came before it.

The Fulfillment, Not the Abolition, of the Law

At this point, a critical clarification is necessary. Jesus was not dismissing or discarding the Torah. He stated plainly in the Sermon on the Mount: "Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them" (Matthew 5:17, ESV). The verb translated "fulfill" is πληρόω (pleroo), to bring to fullness, to complete, to bring to the goal for which something was intended. The law and prophets were always pointing forward to Christ. He was their telos, their end and goal (Romans 10:4, where Paul says Christ is the τέλος of the law for righteousness to all who believe).

Think of an acorn. An acorn contains within it the entire blueprint for an oak tree. When an acorn germinates and grows into a towering oak, the acorn is not destroyed; it is fulfilled. Its entire purpose was to become what it is now. The acorn stage is gone, but nothing of its essential content has been lost; it has been gloriously expanded and realized. This is what Jesus did to the law. He did not throw out the old wineskin and pour the wine on the ground. He said: The old wineskin served its purpose. Now I am providing what the old wineskin has always pointed toward.

No human being could fulfill the law's demands, not the Pharisees with their scrupulous rule-keeping, not John's disciples with their rigorous fasting. "For all who rely on works of the law are under a curse" (Galatians 3:10, ESV). Only Jesus, the ἀμνὸς τοῦ θεοῦ, "the Lamb of God" (John 1:29), who knew no sin (2 Corinthians 5:21), could meet God's perfect standard. And in meeting it, He offers His righteousness to all who believe.

Grace Cannot Be Contained in a Legal Framework

What, then, is the new wine? It is the Gospel of grace, the good news that salvation comes not through human effort, ceremony, or religious performance, but through faith in Jesus Christ. Paul articulates this with crystalline precision: "For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast" (Ephesians 2:8–9, ESV). The word χάρις (charis), grace, is the defining characteristic of the New Covenant. It is God's unmerited, freely given favor toward those who deserve only judgment.

Grace cannot be contained within a legal framework because law and grace operate on fundamentally different principles. Law says: perform and be accepted. Grace says: be accepted, then live transformed. To pour grace into the structure of law, to say that salvation is partly of grace and partly of one's own religious performance, is to put new wine into an old wineskin. The container will not hold. "For if justification were through the law, then Christ died for no purpose" (Galatians 2:21, ESV).

This is what made the Gospel so difficult for many Jewish hearers, including, as Acts 10–11 recounts, many Jewish Christians who struggled to accept that Gentiles could receive the Spirit without first becoming Jews. The old wineskin was deeply familiar, deeply comforting, deeply tied to their identity. Luke notes this human dynamic in the final verse of his wineskin passage: "And no one after drinking old wine desires new, for he says, 'The old is good'" (Luke 5:39, ESV). The Greek χρηστός here is significant: it means good, useful, mellow, pleasant to the palate. Old wine is smoother, more refined, more comfortable on the palate than new wine, which is sharp and unfinished. It is human nature to prefer the comfortable and familiar. But preference is not the same as truth. The new wine of grace, though less immediately familiar to those weaned on the law, is the wine that gives life.

New Wineskins for Every Generation

The application of this parable extends beyond its first-century context. Throughout the history of the Church, the Holy Spirit has repeatedly moved in fresh, unexpected ways, and the religious structures of each era have sometimes proved to be the old wineskins that could not contain what God was doing.

The word for the Spirit, πνεῦμα (pneuma), carries connotations of wind and breath, something alive and dynamic and inherently difficult to confine. Jesus told Nicodemus: "The wind blows where it wishes, and you hear its sound, but you do not know where it comes from or where it goes. So it is with everyone who is born of the Spirit" (John 3:8, ESV). The Spirit is not domesticated. He cannot be scheduled, systematized, or institutionalized into rigid forms that substitute performance for presence.

This does not mean that all structure is wrong, or that any particular tradition is simply an "old wineskin" to be discarded. Jesus was not teaching contempt for religious form. He taught that no human structure can serve as the permanent container of a living God. The new wineskin of the early Church eventually became an old wineskin for some who encountered subsequent movements of the Spirit. What matters is this: is the container serving the wine, or has preserving the container become more important than the wine itself?

The Church in every age must ask: are we clinging to old religious structures, even good, Bible-based ones, out of comfort and familiarity, when God is calling us to receive what He is doing in new ways? Are we so committed to the forms of our particular tradition that we would miss the fresh work of the Spirit if it arrived in an unexpected vessel?

Both Are Preserved

The most hopeful phrase in the entire parable may be the simplest one. Jesus concludes in Matthew 9:17 with these words: "But new wine is put into fresh wineskins, and so both are preserved" (ESV). The Greek is ἀμφότεροι συντηροῦνται, "both are preserved together." The verb συντηρέω (suntereo) means to keep safe, to preserve, to maintain in safety. It is the same word used in Luke 2:19, where Mary "treasured up all these things, pondering them in her heart."

This is the promise: when the new wine is received into a new, prepared, supple wineskin, nothing is lost. The wine is preserved. The wineskin is preserved. The Gospel of grace, received into a heart that is genuinely open, soft and flexible before God, not hardened by religious self-reliance, results not in destruction but in preservation and flourishing.

The old covenant was not wasted. Every sacrifice, every fast, every festival, every prophecy served its sacred purpose of pointing forward to Christ. But now that Christ has come, to cling to the old forms as though He had not arrived, to fast as though the Bridegroom were still absent when He has come, died, risen, and sent His Spirit, is to miss the entire point of the story. It is to prefer the shadow over the substance, the acorn over the oak, the old wine over the new.

The Invitation

The question Jesus left in the air above John's disciples is the question He leaves with us: What are you doing with the new wine? Are you attempting to pour the grace of Christ into the container of self-righteous religious performance? Are you adding fasting and ritual and rule-keeping to the work that Christ declared τετέλεσται, "finished" (John 19:30)? Or are you presenting yourself to God as a new wineskin, pliable, humble, emptied of self-sufficiency, ready to be stretched by the work of the Spirit?

The Gospel asks us to do what the old wineskin could not: to expand. To grow. To be made new, not merely improved but transformed. The Greek word for this transformation is μεταμορφόω (metamorphoo), the word from which we get our English "metamorphosis." Paul uses it in Romans 12:2: "Do not be conformed to this world, but be transformed by the renewal of your mind." This is what the new wine does to a new wineskin. It does not leave the container unchanged. The wine works from the inside, and the wineskin must expand to receive it.

Jesus came not to mend a torn garment, not to patch a leaking wineskin, not to reform a failing religious system. He came to inaugurate a covenant written not on stone tablets but on human hearts (Jeremiah 31:33; 2 Corinthians 3:3). He came to bring not religion but relationship. Not law but life. Not the shadow but the substance.

The Bridegroom has come. The feast has begun. The new wine is poured. May we be, in every generation, in every heart, ἀσκοὺς καινούς: fresh wineskins, ready to be filled.

Drawing Closer to God Through the Spiritual Discipline of Fasting

In a world filled with constant distractions, endless notifications, overflowing schedules, and the relentless pursuit of material comfort, the ancient practice of fasting stands as a profound invitation to spiritual depth. Fasting, at its core, is more than mere abstention from food; it is a deliberate act of self-denial that redirects our focus toward God, fostering humility, dependence, and clarity in our relationship with Him. Throughout Scripture, fasting emerges not as an optional ritual but as a vital discipline that prepares the heart for divine encounter, guidance, and transformation. This blog post explores the spiritual discipline of fasting through key biblical passages: Matthew 4:1-4, Acts 13:1-3, Daniel 9:2-3, and 2 Chronicles 20:1-4, using the English Standard Version (ESV) of the Bible. We will exegete these texts, delving into their historical and theological contexts, while highlighting significant keywords and phrases from the original languages (Greek for the New Testament and Hebrew for the Old Testament). By examining these examples, we uncover how fasting serves as a bridge between human frailty and God's sovereign power, equipping believers to align with His will.

Fasting has two essential components: abstention, which removes distractions like food that can dominate our thoughts and energies, and undivided attention on God, which opens the door to deeper communion with Him. As we journey through these passages, we'll see fasting not as a means to manipulate God or hasten His answers, but as a preparation to perceive our circumstances through His perspective and respond accordingly. Whether individual or corporate, fasting cultivates a hunger for God's presence over earthly sustenance, reminding us that true life comes from every word that proceeds from His mouth.

Jesus' Fasting in the Wilderness: A Model of Spiritual Preparation (Matthew 4:1-4)

The Gospel of Matthew provides one of the most vivid portrayals of fasting in the life of Jesus Himself. This account occurs immediately after His baptism, marking the onset of His public ministry. Matthew 4:1-4 (ESV) reads:

Then Jesus was led up by the Spirit into the wilderness to be tempted by the devil. And after fasting forty days and forty nights, he was hungry. And the tempter came and said to him, “If you are the Son of God, command these stones to become loaves of bread.” But he answered, “It is written, ‘Man shall not live by bread alone, but by every word that comes from the mouth of God.’”

Exegesis of the Passage

Verse 1 sets the scene with divine intentionality: "Then Jesus was led up by the Spirit into the wilderness to be tempted by the devil." This transition ("then") connects directly to Jesus' baptism in Matthew 3:13-17, where the heavens opened, the Spirit descended like a dove, and God declared Jesus as His beloved Son. The wilderness, a barren and isolating place, echoes Israel's 40-year wanderings in the desert (Exodus 16-17; Deuteronomy 8), symbolizing a time of testing and dependence on God. Here, Jesus is not wandering aimlessly but is purposefully "led up" by the Spirit, indicating God's sovereign guidance even into trial. The purpose clause, "to be tempted by the devil", reveals that this fast is no accident but a divinely ordained confrontation with evil, preparing Jesus for His messianic role.

In verse 2, we read, "And after fasting forty days and forty nights, he was hungry." The duration of 40 days mirrors significant biblical periods of preparation and revelation, such as Moses on Mount Sinai (Exodus 34:28) and Elijah's journey to Horeb (1 Kings 19:8). Jesus' hunger is stated matter-of-factly, underscoring His full humanity, He experiences physical weakness just as we do. Yet, this vulnerability becomes the backdrop for spiritual victory.

Verse 3 introduces the tempter's strategy: "And the tempter came and said to him, ‘If you are the Son of God, command these stones to become loaves of bread.’” The devil's challenge questions Jesus' identity, affirmed at baptism, and tempts Him to use divine power for self-gratification, bypassing dependence on God. This echoes Israel's grumbling in the wilderness, where they demanded bread from heaven (Exodus 16).

Jesus' response in verse 4 is a direct quotation from Deuteronomy 8:3: "But he answered, ‘It is written, “Man shall not live by bread alone, but by every word that comes from the mouth of God.”’" Here, Jesus affirms that spiritual sustenance from God's word surpasses physical needs, modeling perfect obedience and trust.

Keywords and Phrases from the Original Greek

Delving into the Greek text enriches our understanding. The word for "led up" is anēchthē (from anagō, Strong's G321), implying being guided or brought up, emphasizing the Spirit's active role in directing Jesus. "Spirit" is Pneumatos (from pneuma, Strong's G4151), referring to the Holy Spirit, the third person of the Trinity, who empowers and leads believers today as well.

"Fasting" translates nēsteusas (aorist participle of nēsteuō, Strong's G3522), meaning to abstain from food for spiritual purposes, often connoting mourning, repentance, or seeking God. This term highlights fasting as an intentional discipline, not mere hunger.

"Tempted" is peirasthēnai(infinitive of peirazō, Strong's G3985), which can mean to test or entice to sin, reflecting both divine testing (as in Genesis 22:1) and satanic temptation. In context, it underscores the devil's attempt to derail Jesus' mission.

The quotation in verse 4 uses anthrōpos(Strong's G444) for "man," denoting humanity broadly; artō (Strong's G740) for "bread," symbolizing earthly provision; and rhēmati (Strong's G4487) for "word," referring to God's uttered decrees, which sustain life more profoundly than food.

Parallels in the Synoptic Gospels

While Matthew's account is detailed, Luke 4:1-4 (ESV) emphasizes Jesus being "full of the Holy Spirit" and "led by the Spirit," adding that "he ate nothing during those days." Mark 1:12-13 (ESV) is concise, noting that the Spirit "drove him out" (ekballei, Strong's G1544, implying urgency) and mentioning wild animals and angelic ministry, which highlights both isolation and divine care. These parallels affirm the historicity and theological unity of Jesus' fast as a pattern for believers facing temptation.

This passage teaches that fasting strengthens spiritual resolve, enabling us to prioritize God's word over immediate gratification. In our lives, fasting can prepare us for trials, heightening our sensitivity to the Spirit's leading.

Jesus' Teaching on the Practice of Fasting (Matthew 6:16-18)

Building on His example, Jesus provides practical instruction on fasting in the Sermon on the Mount. Matthew 6:16-18 (ESV) states:

“And when you fast, do not look gloomy like the hypocrites, for they disfigure their faces that their fasting may be seen by others. Truly, I say to you, they have received their reward. But when you fast, anoint your head and wash your face, that your fasting may not be seen by others but by your Father who is in secret. And your Father who sees in secret will reward you.”

Exegesis of the Passage

This teaching follows instructions on giving (6:1-4) and prayer (6:5-15), forming a triad of piety acts. Jesus assumes fasting ("when you fast") as a regular practice, not an "if." He contrasts hypocritical fasting, marked by outward displays for human approval, with authentic fasting done in secret for God's eyes alone.

In verse 16, "do not look gloomy like the hypocrites" critiques those who "disfigure their faces" to advertise their piety. The reward they seek is fleeting praise from others.

Verse 17-18 shifts to a positive command: "anoint your head and wash your face," maintaining a normal appearance to keep fasting private. The promise is that God, who "sees in secret," will reward genuine devotion, perhaps with spiritual insight, answered prayer, or deeper intimacy.

Keywords and Phrases from the Original Greek

"Fasting" again is nēsteuō (Strong's G3522), as in Matthew 4. "Hypocrites" is hypokritai(Strong's G5273), originally meaning stage actors, implying pretense or insincerity.

"Disfigure" is aphanizousin(Strong's G853), meaning to make unattractive or obscure, here ironically to draw attention. "Anoint" is aleipsai (from aleiphō, Strong's G218), referring to applying oil, a common hygienic practice symbolizing joy. "Wash" is nipsai (from niptō, Strong's G3538), meaning to cleanse, emphasizing normalcy.

"Reward" is misthon(Strong's G3408), denoting wages or recompense, pointing to eternal blessings from God. "In secret" (en tō kryptō, Strong's G2927) underscores God's omniscient gaze on the heart.

Jesus' teaching reminds us that fasting's value lies in its sincerity, not spectacle. In application, modern believers might fast privately during Lent or personal crises, seeking God's reward over social media acclaim.

Fasting in the Early Church: Guidance for Mission (Acts 13:1-3)

Turning to the New Testament church, Acts 13:1-3 illustrates corporate fasting for divine direction. The ESV reads:

Now there were in the church at Antioch prophets and teachers: Barnabas, Simeon who was called Niger, Lucius of Cyrene, Manaen a lifelong friend of Herod the tetrarch, and Saul. While they were worshiping the Lord and fasting, the Holy Spirit said, “Set apart for me Barnabas and Saul for the work to which I have called them.” Then after fasting and praying they laid their hands on them and sent them off.

Exegesis of the Passage

Set in Antioch, a diverse hub of early Christianity, verse 1 lists leaders: prophets (who proclaim God's word) and teachers (who instruct). This multicultural group, comprising Barnabas (a Jewish Cypriot), Simeon Niger (possibly of African descent), Lucius (from Cyrene), Manaen (connected to Herod), and Saul (also known as Paul), reflects the church's unity.

Verse 2 describes their activity: "While they were worshiping the Lord and fasting, the Holy Spirit said..." Worship and fasting create space for God's voice, leading to the command to "set apart" Barnabas and Saul for missionary work. This marks a pivotal shift, launching the first intentional Gentile mission.

Verse 3 shows response: more fasting and prayer, then commissioning via laying on hands, symbolizing blessing and authority.

This passage portrays fasting as a communal preparation for God's call, resulting in obedience and mission expansion.

Keywords and Phrases from the Original Greek

"Worshiping" (or "ministering") is leitourgountōn (from leitourgeō, Strong's G3008), meaning public service or liturgical worship, implying structured devotion. "Fasting" is nēsteuontōn  (from nēsteuō, Strong's G3522), the present participle indicating ongoing action.

"Holy Spirit" is to pneuma to hagion(Strong's G4151 and G40), the divine person who speaks directly. "Set apart" is aphorizate (from aphorizō, Strong's G873), meaning to separate for a special purpose, like consecration.

Fasting here facilitates hearing the Spirit, applicable today for church decisions like leadership appointments or outreach initiatives.

Daniel's Fasting for Prophetic Insight (Daniel 9:2-3)

In the Old Testament, Daniel exemplifies individual fasting amid exile. Daniel 9:2-3 (ESV) states:

in the first year of his reign, I, Daniel, perceived in the books the number of years that, according to the word of the LORD to Jeremiah the prophet, must pass before the end of the desolations of Jerusalem, namely, seventy years. Then I turned my face to the Lord God, seeking him by prayer and pleas for mercy, with fasting and sackcloth and ashes.

Exegesis of the Passage

Verse 2 recounts Daniel studying Jeremiah's prophecy (Jeremiah 25:11-12; 29:10) about 70 years of Babylonian captivity. "Perceived" implies a thorough examination leading to a deeper understanding, which in turn prompts action.

Verse 3 describes his response: turning his "face" to God in prayer, pleas, fasting, sackcloth, and ashes, symbols of mourning and repentance. This fast seeks mercy for Israel's restoration, culminating in Gabriel's revelation (9:20-27).

Daniel's fast demonstrates how Scripture study combined with fasting yields divine clarity.

Keywords and Phrases from the Original Hebrew

"Perceived" (or "understanding") is biyn (Strong's H995), meaning to discern or gain insight, highlighting intellectual and spiritual comprehension.

"Fasting" is tsom(Strong's H6685), denoting abstention from food for solemn purposes. "Prayer" is tephillah(Strong's H8605), a formal petition. "Pleas for mercy" (supplications) is tachanun (Strong's H8467), imploring grace.

"Sackcloth" is saq(Strong's H8242), coarse cloth worn in grief; "ashes" is 'epher(Strong's H665), symbolizing humility.

"Seeking" is from baqash(Strong's H1245), to search diligently. Daniel's example encourages fasting when seeking understanding of God's promises, perhaps during personal Bible study or times of confusion.

Corporate Fasting in Crisis: Jehoshaphat's Call (2 Chronicles 20:1-4)

Finally, 2 Chronicles 20:1-4 depicts national fasting in response to threat. The ESV reads:

After this the Moabites and Ammonites, and with them some of the Meunites, came against Jehoshaphat for battle. Some men came and told Jehoshaphat, “A great multitude is coming against you from Edom, from beyond the sea; and, behold, they are in Hazazon-tamar” (that is, Engedi). Then Jehoshaphat was afraid and set his face to seek the LORD, and proclaimed a fast throughout all Judah. And Judah assembled to seek help from the LORD; from all the cities of Judah they came to seek the LORD.

Exegesis of the Passage

Verses 1-2 describe the invasion by a coalition, evoking fear in King Jehoshaphat. This crisis tests Judah's faith post-reforms (2 Chronicles 19).

Verse 3: Jehoshaphat "set his face to seek the LORD" and "proclaimed a fast," turning fear into faith through national discipline.

Verse 4: The people "assembled" from all cities, uniting in seeking God, leading to victory (20:5-30).

This shows corporate fasting as a unifying response to peril, inviting God's intervention.

Keywords and Phrases from the Original Hebrew

"Afraid" is yare'(Strong's H3372), godly fear prompting action. "Set his face" implies determination, akin to Daniel.

"Seek" is darash (Strong's H1875), to inquire of God diligently.

"Proclaimed a fast" uses qara' (Strong's H7121, to call) and tsom(Strong's H6685). "Assembled" (gathered) is qabats (Strong's H6908), to collect together.

This corporate model applies to churches or nations facing challenges, like during pandemics or social unrest, fostering unity and dependence on God.

The Purpose and Practice of Fasting Today

Synthesizing these passages, fasting emerges as a multifaceted discipline: preparation for temptation (Matthew 4), sincere devotion (Matthew 6), communal discernment (Acts 13), personal insight (Daniel 9), and crisis response (2 Chronicles 20). It isn't about coercing God but aligning our hearts with His, abstaining from distractions to heighten receptivity.

Historically, fasting has appeared in various forms: absolute (no food or water, e.g., Esther 4:16), partial (Daniel 1:12), or extended (as in Jesus' 40-day fast). Original languages reveal nuances: Greek nēsteuōemphasizes religious intent, Hebrew tsom connotes solemnity.

In practice, start small, perhaps a meal or day, combining with prayer and Scripture. Remember, the goal is intimacy with God, not legalism. If health concerns arise, consult professionals; spiritual fasting can adapt (e.g., media fasts).

Fasting prepares us to see situations through God's eyes, as in Jehoshaphat's victory or the Antioch church's mission. It fosters humility, as in Daniel's sackcloth, and reliance on God's word, as Jesus demonstrated.

In our fast-paced era, rediscovering fasting can counteract consumerism, drawing us closer to the One who sustains us. As Jesus quoted, we live not by bread alone but by God's every word. May these biblical examples inspire you to embrace this discipline, experiencing God's encouragement and direction anew.
