Short answer: Matthew 6:16–18 teaches that fasting should be a private act of devotion to God, not a public display for human approval. Jesus condemns hypocrites who fast visibly to impress others, promising that God sees and rewards authentic spiritual devotion done in secret. The text focuses on the motive behind fasting, not the practical details like whether to drink water. Christians have freedom to fast in ways that honor God privately.
Jesus redefines fasting for his disciples
In Matthew 6:16–18, Jesus addresses fasting as part of his Sermon on the Mount teachings. He contrasts the hypocritical practices of religious leaders with the genuine devotion he expects from his followers. While fasting was a common Jewish spiritual discipline, Jesus critiques those who fast for public recognition. He describes how hypocrites disfigure their faces to appear pious, seeking applause from others rather than God. This sets the stage for Jesus’ corrective teaching, showing that true fasting isn’t about outward performance but inward humility before God. The passage assumes fasting as a normal practice but reorients its purpose.
Jesus’ instructions in Matthew 6:17–18 emphasize secrecy and sincerity. Instead of drawing attention to their fasting, disciples are told to anoint their heads and wash their faces, maintaining normal appearances. This contrasts sharply with the theatrics of the hypocrites. The focus shifts from human observation to God’s perspective, with Jesus highlighting that the Father sees what is done in secret. This echoes earlier teachings in the Sermon on the Mount about avoiding religious ostentation. The mention of rewards connects to Jesus’ kingdom priorities, reminding disciples that God’s approval matters more than human recognition.
The passage concludes with a promise of reward from the Father, who sees in secret. This reward isn’t earned through fasting but comes as a result of aligning with God’s values. Jesus’ teaching here parallels his earlier instructions on prayer and almsgiving, forming a cohesive critique of superficial religion. By contrasting hypocritical fasting with genuine devotion, Jesus redefines spiritual practices for his disciples. The emphasis remains on sincerity, humility, and God-centered motives, challenging believers to examine their own hearts rather than perform for others’ approval.
Jesus redefines fasting as a private act of devotion
Jesus critiques religious showmanship by describing hypocrites who intentionally make themselves look haggard when fasting. The phrase “disfigure their faces” suggests deliberate neglect of normal hygiene, unwashed faces, unkempt hair, perhaps ashes, to signal their spiritual effort to others. This performative fasting earns immediate social rewards: admiration for appearing devout. But Jesus bluntly says that public recognition is their only payoff. The problem isn’t fasting itself but using it as spiritual theater. When devotion becomes a performance, the audience’s applause replaces God’s approval. The act may be religious, but the motive hollows it out.
In contrast, Jesus tells his followers to maintain normal grooming, “anoint your head and wash your face”, so no one detects their fast. Anointing with oil and washing were daily practices of self-care, not signs of indulgence. The point isn’t deception but rejecting the hypocrisy of manufactured misery. Fasting is reoriented from public display to private communion with God. The disciple’s ordinary appearance becomes a spiritual countermeasure, ensuring the fast stays between them and their Father. Jesus assumes fasting will happen but insists it must be invisible to others to remain authentic. The audience shrinks from many to One.
The passage hinges on two kinds of reward: immediate human recognition versus future divine approval. Hypocrites get what they wanted, praise from people, but forfeit deeper blessing. Disciples who fast secretly are seen by the only audience that matters. Jesus doesn’t command fasting as a duty but reshapes its practice for those who choose it. The emphasis falls on God’s attentiveness to hidden faithfulness. This isn’t about earning favor but directing devotion rightly. Whether one eats or fasts, the call is the same: live for the Father’s smile, not the crowd’s applause.
Jesus expects fasting but forbids showing it
Jesus assumes his followers will fast but warns against doing it like the religious show-offs who make sure everyone notices. These hypocrites deliberately look miserable so people will admire their discipline. Jesus says such performers already have their reward, human applause, and miss God’s approval. The problem isn’t fasting itself but turning a spiritual practice into theater. This continues Jesus’ theme from earlier in the chapter where he criticized public prayer and giving done for applause. Spiritual habits aren’t bad, but using them to impress others twists them into the opposite of true devotion.
Instead of disfiguring their faces, Jesus tells his disciples to wash up and look normal when fasting. Anointing the head with oil was a sign of everyday freshness, not mourning. The point isn’t about hygiene but motive: fast for God alone, not observers. Jesus promises the Father sees what’s done in secret and will respond, contrasting with the hypocrites who settle for human praise. This doesn’t mean fasting must always be completely hidden, others might notice you skipping meals, but it forbids drawing attention to your spiritual effort. The reward comes from God’s notice, not others’ admiration.
This passage doesn’t define how to fast but why. Jesus isn’t legislating techniques like duration or food restrictions but targeting the heart behind the action. The surrounding verses reinforce this: forgiveness precedes fasting (6:14–15), and eternal priorities follow it (6:19–20). Fasting here is one expression of a life oriented around God’s kingdom rather than human approval. While the text expects believers to fast, it never suggests fasting earns God’s favor. Like prayer and giving, it’s a response to grace, not a way to manipulate God. The focus stays on authentic devotion, not performative religion.
How should fasting look different from religious performance?
Jesus contrasts two ways to fast: the hypocrites’ public misery and his followers’ ordinary appearance. The religious leaders deliberately made themselves look haggard to prove their devotion. Jesus calls this: disfiguring their faces, a showy distortion meant to draw attention. His command to wash and anoint reverses that posture, not to hide fasting entirely, but to avoid turning it into theater. The issue isn’t being seen fasting, but fasting to be seen. The text critiques motives, not all visibility. Some believers take this as literal grooming advice; others see a broader call to reject spiritual pretense in any form.
The passage sets one clear limit: fasting must not aim at human applause. Jesus bluntly says those who fast for recognition "have received their reward", the momentary admiration they wanted. The alternative is seeking God’s approval alone, pictured as the Father who "sees in secret." This doesn’t require absolute secrecy, early Christians fasted together in Acts 13, but rules out using fasting to boost one’s reputation. The tension arises when fasting is corporate or involves leadership: does discussing it cross into "being seen"? Jesus’ focus stays on the heart’s direction, not just the eyes on you.
Jesus’ teaching here parallels his warnings about prayer and giving in this sermon, all three reject transactional religion. Fasting isn’t a lever to force God’s hand or a badge of superiority. The Father’s reward comes to those who relate to him personally, not those performing piety. Some church traditions formalize fasting seasons, risking the hypocrisy Jesus condemns; others avoid any structure, potentially losing a helpful discipline. Both must ask: does this draw me to God or to self-display? The text forbids using fasting as a spiritual resume item but leaves room for diverse practices that honor its purpose.
Jesus redefines fasting as a quiet act of trust
Jesus contrasts two kinds of fasting in 6:16–18. Hypocrites disfigure their faces to win human applause, which Jesus says is their only reward. But his followers are to wash their faces and anoint their heads, normal grooming that hides their fast from public view. The difference isn’t in the act itself but in the audience sought. Jesus assumes his people will fast, but he redirects their focus from performing for others to trusting the Father who sees in secret. This isn’t about technique but about relationship with a God who notices what no one else does.
The passage ties directly to Jesus’ identity. As the one who fulfills the Law (5:17), he reforms religious practices corrupted by showmanship. His authority to redefine fasting points beyond human tradition to God’s original intent. The Father’s promised reward in 6:18 also points ahead, the ‘treasures in heaven’ of 6:20 that Jesus secures through his death and resurrection. This isn’t about earning God’s favor; it’s about living as forgiven children (6:14–15) who relate to God as Father. Fasting here is a response to grace, not a ladder to reach it.
Jesus’ teaching transforms fasting from a public display to a private act of dependence. Washing one’s face while fasting means rejecting the hunger games of religious performance. It’s a quiet declaration that God’s approval matters more than human recognition. For Christians, this echoes the gospel itself, we bring nothing to earn salvation, yet we respond with whole-life trust. Whether or not we fast, Jesus’ words challenge us: do we seek the spotlight or the Father’s smile? The answer reveals whether we’re still trying to earn love or resting in the love Christ already won.
Fasting as a quiet act of devotion
In Matthew 6:16–18, Jesus warns against fasting for show. He describes hypocrites who disfigure their faces to make their fasting obvious to others. Their goal is human recognition, and Jesus says they’ve already received their reward, the fleeting approval of people. This isn’t the kind of fasting Jesus commends. Instead, he calls us to fast in a way that doesn’t draw attention. Washing your face and anointing your head are ordinary acts of hygiene, signaling that fasting isn’t about making yourself look miserable. It’s a private act, meant to deepen your relationship with God, not to impress others.
Jesus emphasizes that fasting should be directed toward God, not human observers. He contrasts the hypocrites’ public displays with the quiet, unseen nature of true fasting. When you fast, he says, don’t let others know. Keep it between you and God, who sees what’s done in secret. This doesn’t mean fasting is worthless if someone notices, but it does mean our motives matter. Are we fasting to draw closer to God or to gain admiration? Jesus invites us to seek God’s approval above all else, trusting that he sees and rewards our sincere efforts.
Fasting isn’t about earning God’s favor or proving your spirituality. It’s a voluntary act of devotion, not a requirement for salvation. Jesus assumes his followers will fast but doesn’t command it. The focus is on the heart behind the practice. If you fast, do it to focus on God, not to signal your piety. Maintain your normal routines, avoiding extremes that draw attention. Let this practice remind you of your dependence on God and your desire to seek him above all else. Ultimately, fasting is about aligning your heart with God’s, not about outward appearances or human recognition.
Biblical fidelity check
Jesus critiques fasting done for public admiration, not fasting itself. The hypocrites actively alter their appearance (“disfigure their faces”) to ensure others notice their piety. Jesus commands the opposite: maintain normal grooming (anoint your head, wash your face) so only God sees the fast. This raises questions about corporate fasting or mentioning needs to prayer partners, does that violate secrecy? The text targets performative religion, not all outward expressions. The core issue is seeking God’s approval rather than human praise, whether fasting alone or with others.
The passage warns against turning spiritual discipline into a performance, but doesn’t forbid every outward sign of fasting. Jesus assumes fasting happens (“when you fast”), focusing on motive, not mere visibility. First-century Jews recognized anointed heads and washed faces as signs someone wasn’t fasting; today’s cultural signals differ. The principle remains: don’t manufacture suffering to impress people. Whether drinking water during a fast violates this depends on intent, avoiding dehydration for health differs from abandoning sacrifice. God sees the heart’s intent behind the practice, not just the practice itself.

Frequently asked questions
Does the Bible prohibit telling anyone you're fasting?
Matthew 6:16–18 warns against fasting to gain human approval, not against all mention of fasting. The key is motive: fasting should focus on seeking God, not impressing others. While Jesus encourages secrecy, there may be times it's wise to inform close family or friends for practical reasons, as long as the goal remains private devotion to God.
What counts as “showing off” when fasting as a Christian?
In Matthew 6:16–18, Jesus criticizes hypocrites who disfigure their faces to make their fasting obvious to others. “Showing off” includes any attempt to draw attention to your fasting for human praise rather than seeking God privately. It’s about the heart: fasting becomes performative when it seeks recognition rather than honoring God in secret.
Why doesn't Jesus give specific rules about how to fast?
Matthew 6:16–18 focuses on the motive behind fasting, not the method. Jesus doesn’t specify rules like whether to drink water because the heart matters more than the details. This leaves room for Christians to fast in ways that fit their health, circumstances, and devotion to God, as long as the focus remains on seeking Him privately.
