She started fasting the same month she started a new diet plan, and for a long while, she could not have honestly told you where one practice ended and the other began. Both involved denying herself food. Both left her feeling, by evening, a certain satisfaction at having resisted something. It took a season of real hunger, both physical and spiritual, before she noticed how easily the two had blended into a single habit that looked religious on the surface and functioned almost entirely as self-control dressed up in spiritual language.
I think fasting gets misunderstood this way more often than almost any other spiritual discipline, absorbed into a culture already obsessed with restriction, willpower, and physical control, until its actual purpose becomes nearly impossible to distinguish from a wellness trend wearing slightly more devout clothing.
What Fasting Was Never Meant to Be
Fasting, practiced as a form of self-improvement, treats hunger as something to conquer, a test of discipline proving a person can master their own body through sheer willpower. But this version of fasting produces real pride when it succeeds and real shame when it does not, both responses tied entirely to personal performance rather than to God at all. The Bible presents something different.
Fasting
16 “When you fast, do not look somber as the hypocrites do, for they disfigure their faces to show others they are fasting. Truly I tell you, they have received their reward in full. 17 But when you fast, put oil on your head and wash your face, 18 so that it will not be obvious to others that you are fasting, but only to your Father, who is unseen; and your Father, who sees what is done in secret, will reward you.
Matthew 6:16-18 New International Version
Jesus assumed his followers would fast, offering instruction on how to do it rather than whether to do it at all, but his instruction focused entirely on posture rather than achievement. He warned against fasting visibly, in a way designed to be noticed and admired, and instructed his followers instead to fast quietly, washing their faces and appearing ordinary, so that the practice remained between them and God rather than becoming a public performance of discipline.
That instruction alone reveals something important about the actual purpose. If fasting were primarily about willpower or self-mastery, public visibility would make sense, since achievement generally seeks an audience. Jesus taught the opposite, that fasting done well happens in secret precisely because it was never meant to prove anything to anyone watching, including, in a subtler sense, the person doing the fasting themselves.
Hunger as a Teacher, Not an Enemy
I believe the deepest purpose of fasting involves what physical hunger actually reveals once a person sits inside it honestly rather than simply pushing through it toward a predetermined endpoint. An empty stomach has a peculiar way of exposing what a person has been leaning on for comfort, distraction, and a sense of control, since food often serves all three functions in a way, every single day, without ever being named directly as that.
3 He humbled you, causing you to hunger and then feeding you with manna, which neither you nor your ancestors had known, to teach you that man does not live on bread alone but on every word that comes from the mouth of the Lord.
Deuteronomy 8:3 New International Version
Moses reminded the Israelites, after their long fast in the wilderness, that God had humbled them and let them hunger specifically to teach them that people do not live on bread alone, but on every word that comes from the mouth of God. Notice what the hunger was actually for in that account. Not punishment, and not a test of willpower for its own sake. The hunger existed to reveal a dependence that had been quietly obscured by regular, reliable meals, a dependence on God that easy abundance tends to hide rather than remove.
This reframes what a person is actually meant to notice during a fast. Not simply how long the hunger can be endured, but what surfaces underneath it, irritability that reveals how much comfort had been coming from food rather than from genuine peace, a restless urge to fill the emptiness with something else entirely, a sharper, more honest awareness of dependence on God that regular, comfortable eating had been quietly masking. The hunger itself is not the discipline; it is the doorway into noticing something a full stomach makes easy to ignore.
The Difference Between Restriction and Surrender
I think the clearest test for distinguishing genuine fasting from disguised self-control involves noticing where the attention actually goes during the practice. Restriction, pursued as its own goal, keeps attention fixed on the body, on the discomfort, on the achievement of resisting it successfully. Surrender, the posture fasting is actually meant to cultivate, keeps attention moving outward and upward, toward God, toward prayer, toward the specific need or question the fast was undertaken to bring before Him. A fast disconnected from prayer becomes simply a diet with spiritual branding attached to it.
6 “Is not this the kind of fasting I have chosen:
Isaiah 58:6-7 New International Version
to loose the chains of injustice
and untie the cords of the yoke,
to set the oppressed free
and break every yoke?
7 Is it not to share your food with the hungry
and to provide the poor wanderer with shelter—
when you see the naked, to clothe them,
and not to turn away from your own flesh and blood?
Prophet Isaiah confronted exactly this pattern directly, delivering a message to people who fasted faithfully while continuing to exploit workers and ignore the genuinely needy around them, pointing and asking them whether the fast they had chosen was actually the kind God was looking for. His answer redirected fasting away from personal ritual entirely, toward loosening the chains of injustice, sharing bread with the hungry, and providing shelter for the homeless. A fast, in his account, was never meant to remain a private transaction between a person and their own willpower. It was meant to produce genuine compassion and surrendered dependence, visible in how a person actually treated others once the fast had done its inward work.
This matters very, very much for anyone approaching fasting today, tomorrow, or whenever, largely inside a culture that already treats restriction and discipline as inherently virtuous regardless of their actual purpose. A fast focused entirely on personal achievement, disconnected from prayer and disconnected from any resulting compassion toward others, risks becoming precisely the empty practice prophet Isaiah confronted so directly, technically observed, spiritually hollow.
Practicing Fasting Honestly
For anyone considering fasting as a genuine spiritual practice rather than a wellness habit, a few honest questions will you to clarify the actual posture being brought into it.
What specifically is this fast asking God for, or surrendering to Him? A fast without a genuine question or surrender attached tends to drift quickly back toward simple restriction, since there is nothing else anchoring the practice to an actual relationship with God rather than to the body alone.
What will actually happen with the time and attention freed up by skipping a meal? Fasting that simply removes food while leaving every other habit and distraction untouched misses a significant part of its purpose. Because the time a meal would have occupied deserves to be filled with prayer, scripture, or quiet attention toward God, rather than simply redirected toward other tasks entirely unrelated to the fast’s actual purpose.
How will this fast be held if it becomes physically difficult in a way that raises real health concerns? The Bible does not glorify harm to the body for its own sake, and fasting was never meant to become reckless self-endangerment. A fast held with genuine wisdom includes real attention to physical limits, adjusting or ending the practice honestly if health genuinely requires it, without treating that adjustment as spiritual failure.
And afterward, what actually surfaced during the fast worth bringing honestly before God? Irritability revealed, dependence noticed, a specific need clarified, all of this deserves reflection once the fast ends, rather than being set aside the moment the next meal arrives and ordinary life resumes without a second thought given to what the emptiness actually revealed.

Conclusion
The woman who could not tell where her diet ended and her fasting began was not failing at either practice exactly. She had simply absorbed fasting into a broader cultural obsession with restriction and control, the same way faith itself so easily gets absorbed into a productivity system built for an entirely different purpose.
Fasting was never meant to prove what a person’s willpower could accomplish. My dearest readers, it was meant to reveal what a full life quietly hides, a genuine dependence on God that comfort and abundance make remarkably easy to forget. Practiced honestly, with real prayer and real surrender rather than mere restriction, fasting becomes something richer than a spiritual diet. It becomes a doorway into noticing, plainly and without distraction, exactly how much a person actually needs the God who meets them in the hunger.
