Short answer: In Matthew 6:16–18 Jesus speaks of fasting as something his followers already do, not as a new requirement. His concern is motive and audience: do not fast with a sad, disfigured face so people will notice, but wash and anoint yourself so the fasting stays hidden. The Father who sees in secret is the one who rewards. The passage sets no calendar, season, or day, and it does not command a church observance; it calls for devotion aimed at God rather than at spectators.
Setting and shape of Jesus' teaching on fasting
Matthew 6:16–18 sits inside the Sermon on the Mount, Jesus' extended instruction to his disciples about the life of the kingdom of heaven. Early in that sermon he insists that kingdom righteousness must exceed that of the scribes and Pharisees, and here he shows what that looks like in ordinary religious practice. Giving, prayer, and fasting follow one another as three pillars of Jewish devotion, and each receives the same treatment: a warning about performing for an audience, a command to the disciples, and a promise about the Father. The unit is not an isolated rule about food but one panel in a larger argument about who is watching.
The literary shape is a deliberate contrast pattern. Jesus first describes the hypocrites, who disfigure their faces so that others will notice they are fasting, and he says plainly that they have received their reward. Then he turns to his disciples with a direct command: anoint your head and wash your face. Then comes the promise, that the Father who sees in secret will reward them. The same three-part movement appears in the parallel units on giving and on prayer. Verses 14–15 just before this unit, on forgiving others, keep the whole section anchored in a Father who sees and responds, and the model prayer that follows is addressed to that Father in secret.
The verses that follow widen the frame. Matthew 6:19–20 turns the same logic toward treasure, urging storage in heaven rather than on earth, where moth and rust consume and thieves break in. So the passage is finally about the audience and the account we live before, not merely about skipping meals. Pastors should add a careful word here: fasting can harm people with medical conditions or a history of disordered eating, and this text promises the Father's unseen reward, not physical or emotional results. The reward named is the Father's notice, not a measurable outcome.
What Jesus says about fasting in secret
The word when carries the weight here. Jesus does not say if you fast but when you fast, which treats fasting as an expected practice among his hearers rather than something new he is introducing. He assumes it will happen and goes straight to how. The contrast he draws is not between fasting and not fasting but between fasting done for an audience and fasting done before the Father. That distinction sets the tone for everything that follows in these three verses, and it keeps the passage from becoming either a command to fast or a dismissal of fasting.
Jesus names the problem with a sharp word: hypocrites, meaning those whose visible religious behavior is staged for an audience. They disfigure their faces, making themselves look grim so others can tell something religious is happening. Of them Jesus says they have received their reward, which means their payment is complete; human notice is all they get. His alternative is ordinary grooming, anoint your head and wash your face, so that appearance does not advertise the fast. The point is not secrecy as a technique but fasting directed to the Father rather than performed for spectators.
The phrase in secret describes the Father's unseen seeing, not a location you can find. Jesus is not asking people to hide in a room but to fast before the one who sees what no one else sees. Two cautions belong with this text. Fasting can harm those with medical conditions or a history of disordered eating, so pastors should speak plainly about that. And the promise here is the Father's unseen reward, not physical or emotional results. Grace comes first: we fast as those already seen and known by him.

Fasting for the Father who sees in secret
Jesus begins with an assumption, not a command: when you fast, not if. Fasting was already woven into the devotion of God's people, and he treats it as expected. His concern is the audience. The hypocrites disfigure their faces so others will notice their discipline. Jesus says to anoint your head and wash your face, ordinary grooming that hides the fast rather than advertises it. The practice stays; the performance goes. He does not institute a season, a calendar, or a particular day here. He addresses motive in something his disciples already do, and he locates the reward with the Father who sees what is hidden.
The surrounding verses set the pattern. Matthew 6 sits in the Sermon on the Mount, where kingdom righteousness exceeds that of the scribes and Pharisees. Giving, prayer, and fasting follow one another, and each gets the same treatment: no trumpet, no public display, no gloomy face. The Lord's prayer just before this addresses the Father in secret, matching the secrecy Jesus asks for here. Immediately before, Matthew 6:14 says, “For if you forgive men their trespasses, your heavenly Father will also forgive you.” The Father who sees and responds frames the whole section, and verses 19 and 20 turn the same logic toward treasure stored in heaven rather than earth.
Two cautions belong with this text. First, fasting is a real expression of devotion, but it is not a command tied to a church calendar, and the reward promised is the Father's unseen notice, not physical or emotional results. Second, fasting can harm people with medical conditions or a history of disordered eating, and pastors should say so plainly. The passage gives no guarantee of healing or relief. It calls for devotion aimed at the Father rather than at observers, and it leaves the timing and the form to wise, ordinary Christian freedom.
Fasting, secrecy, and the limits of the text
Jesus begins with an assumption rather than a command: when you fast, do not look like the hypocrites. The picture is vivid. They make their faces look miserable and disfigure them so others will notice their devotion. Jesus says they have their reward already, meaning the attention they wanted. His alternative is almost comically ordinary: wash your face, anoint your head, carry on looking normal. The point is not that fasting must be hidden from every human being, but that it is directed to the Father who sees in secret. The reward promised is the Father's unseen reward, not physical or emotional results. Fasting here is devotion aimed at God, not a performance aimed at an audience.
Evangelical readers agree on that much and then part ways. Some argue the church is free to set seasons of fasting and repentance, Lent included, as a matter of Christian liberty, so long as the motive runs toward God rather than human approval. Others worry that a fixed congregational calendar invites exactly the display Jesus warns against, and that fasting should stay voluntary and private. The text itself sets the limits: it neither commands a forty day season nor forbids one, and it says nothing about ashes, liturgy or church authority. What stays central across the disagreement is direction and motive. Fasting is toward the Father, kept from self promotion, and never treated as a way to earn favor.
Two cautions belong with this passage. First, these are commands to disciples of Jesus, given to his followers, not Israel's covenant obligations carried over unchanged. Second, pastors should speak plainly about the body. Fasting can harm people with medical conditions or a history of disordered eating, and no verse here promises physical or emotional relief. The Father who sees in secret is the reward, and he is not manipulated by skipped meals. Read alongside 6:14–15, where forgiveness is tied to forgiving others, the passage keeps pointing away from technique and toward a heart honestly turned toward God.
Fasting before the Father who sees in secret
Jesus has just taught his disciples to pray, and he continues with fasting in the same breath. The pattern is identical: the hypocrites make their faces sad and disfigure them so that others notice. Their reward is settled already, Jesus says, because the audience they wanted was human. His disciples are told to anoint the head and wash the face, ordinary grooming that hides the practice rather than advertising it. The point is not secrecy for its own sake but direction: fasting is aimed at the Father, not at a reputation. Jesus speaks here as the teacher of the kingdom, describing a life that runs on God's approval rather than other people's attention.
The promise attached is specific. Your Father, who sees in secret, will reward you. Notice who is watching: not a distant judge keeping score, but a Father. The gospel does not present this reward as wages earned by skipping meals, and Jesus is not selling a transaction. He is describing the regard of a Father who is already turned toward his children in Christ. That is why fasting belongs with prayer and giving as a way of living before a God who has reconciled his people to himself, not as a lever to pry blessings loose. The reward is his notice, his pleasure, his keeping.
Two cautions belong with this text. First, fasting can genuinely harm people with medical conditions or a history of disordered eating, and no verse here requires anyone to fast in a way that damages the body. Second, the promise is the Father's unseen reward, not physical or emotional results; Jesus guarantees the Father's regard, not a particular outcome. Read this way, the passage points past itself to Christ, who taught the kingdom, who would later fast and be tempted in the wilderness, and who opened the way to the Father who sees in secret.
Fasting quietly before the Father who sees
Jesus pictures the fasting he has in mind with two ordinary verbs: anoint your head and wash your face (6:17). That is not a religious performance. It is the normal morning routine of a person in that world, done so that no one can tell from your appearance that you are fasting. The hypocrites in 6:16 do the reverse. They disfigure their faces so that others will notice. Jesus does not measure the fast by its length or severity here. He asks who is watching. If the fast is aimed at an audience of people, the notice they give is the whole reward, and there is nothing left for the Father to give in secret.
So the honest work begins before the fast does. Ask why you are doing it. Is this devotion to God, or a lever for getting what you want from him? Jesus treats fasting as a voluntary discipline, not a bargain that obliges God to send health, breakthrough, or emotional relief. He promises the Father's unseen attention, not physical or emotional results. Pastors should say plainly that fasting can harm people with medical conditions or a history of disordered eating, and that skipping food is never a test of spiritual maturity. Skipping the announcement is the easy part. Examining the motive is the real work.
Where you have fasted to be seen, name it for what Jesus calls it and bring it to him. The forgiveness he gives is not withheld until you feel bad enough. Confess the hypocrisy, receive grace, and begin again without turning the fast into a new way to earn a standing you already have. Then keep the ordinary routines. Wash your face, go to work, eat or abstain without signalling either way. The Father who sees in secret is the audience you are learning to live before, and his quiet attention is enough for the day in front of you.
Biblical fidelity check
Matthew 6:16–18 was read as instruction to disciples already expected to fast, not as a command to invent a practice. The main risk is overreading: treating “when you fast” as a mandate for a fixed calendar, or treating the secrecy clause as a rule against all public worship. Jesus targets staging, not scheduling. The hypocrites made their faces grim so others would notice; the remedy is ordinary grooming, so appearance advertises nothing. “In secret” names the Father's unseen seeing, and “they have received their reward” means human notice is the whole payment.
Evangelical readers agree Jesus assumes fasting and condemns display, but differ on Lent and Ash Wednesday. Some say the church may set seasons of fasting and repentance under Christian liberty, if the motive is toward God. Others say fixed calendars risk exactly what Jesus warns against, and fasting should stay voluntary and private. The text neither commands a forty day season nor forbids one, and it says nothing about ashes or church authority. What stays central: fasting is directed to the Father, kept from self promotion, and never treated as earning favor.

Frequently asked questions
Does the Bible require Christians to fast during Lent?
This passage does not command fasting at all, and it says nothing about Lent; it assumes fasting will happen and teaches how to do it. Jesus says "Moreover when you fast, don’t be like the hypocrites, with sad faces." (Matthew 6:16), addressing those already fasting rather than requiring it. His concern is motive: not being seen by men, but by your Father who sees in secret. So Lenten fasting is a wisdom choice, not a biblical mandate.
Is Ash Wednesday in the Bible, and should Christians observe it?
Ash Wednesday is not in the Bible, and Matthew 6:16–18 never commands a marked day of fasting; it assumes fasting happens and tells you how to do it. Jesus says to anoint your head and wash your face so that you are not seen by men to be fasting, but by your Father who is in secret. The passage regulates the heart behind fasting, not a calendar date, so observing or skipping Ash Wednesday stays a matter of Christian freedom rather than command.
How can I fast in a way that stays between me and God, without other people finding out?
Jesus answers directly: wash your face and go about looking normal, so that only your Father who sees in secret knows you are fasting (6:17–18). The hypocrites in this passage fast in order to be noticed, and Jesus says their public attention is the whole of their reward. Fasting is directed toward God, not toward an audience, so the point is not hiding food but refusing to perform. Your Father sees what is secret, and Jesus leaves the reward with him rather than naming what it will be.
