We have now reached the middle of Great Lent. By this point many people have settled into the rhythm of fasting. Certain foods have been set aside, meals have been adjusted, and the physical discipline has become familiar. But this is exactly the moment when an important question must be asked: What is fasting really for?

If fasting becomes only a change of diet, then we have missed its purpose. The Church never intended fasting to be merely an exercise of the body. It is primarily an exercise of the soul. Food is only the starting point. The deeper work happens in the heart.

The prophet Isaiah warned the people of Israel about this misunderstanding. They fasted, yet their behavior remained unchanged. Through the prophet, God asks:
“Is this the fast that I have chosen?” (Isaiah 58:5)

True fasting, God explains, is not simply abstaining from food while continuing to live with the same anger, injustice, and selfishness as before. Fasting must lead to transformation.

St. John Chrysostom speaks about this with striking clarity:

“Do you fast? Give me proof of it by your works.”

He then explains what that proof looks like. If you see a poor person, show mercy. If you see an enemy, be reconciled. If you see someone honored, do not envy him. Let not only the mouth fast from food, but let the eyes, the ears, the hands, and the tongue fast from sin. What good is it, he asks, to abstain from meat while we “bite and devour” one another with gossip, slander, and anger?

This is why fasting is a form of training. It teaches the soul that appetite is not the master.

Our world constantly trains us in the opposite direction. Every desire demands immediate satisfaction. Every discomfort must be removed. Every craving must be indulged. Comfort becomes the highest value. But as we reflected earlier in the article “The Cost of Comfort,” a life built around ease slowly weakens the will.

Fasting reverses that process.

When we deny ourselves something good and lawful, we strengthen the ability to resist what is harmful and sinful. When the body learns restraint, the soul learns freedom. Appetite loses its authority.

The Apostle Peter describes this growth as a progression of virtues:
“Make every effort to add to your faith goodness; and to goodness, knowledge; and to knowledge, self-control; and to self-control, perseverance; and to perseverance, godliness.” (2 Peter 1:5–6)

Notice the order. Faith must grow into self-control, and self-control must grow into perseverance. Fasting is one of the ways this training happens. It disciplines the will so that the Christian learns to choose what is right rather than simply what is desired.

This is why fasting cannot remain a practice for Lent alone. Great Lent is like a training camp. Just as soldiers train intensely before battle or athletes prepare before a major competition, the Church gives us these forty days to sharpen our discipline. But the purpose of training is not the camp itself. It is the life that follows.

Fasting is meant to train the whole person. It should make us more attentive in prayer, quicker to humility, and more generous in brotherly love. A true fast softens the heart toward the poor, restrains the tongue from gossip, calms anger, and teaches patience with those around us. It should lead us to reconcile with those we have wronged, to forgive those who have wronged us, and to guard our thoughts more carefully. When fasting begins to shape these things—our prayer, our speech, and our relationships—then it is doing its real work. The goal is not simply to endure a season without certain foods, but to form a life that is no longer ruled by appetite, pride, or comfort. Fasting teaches us to say no to ourselves so that we can say yes to God, and to live with the freedom of a soul that has learned discipline.

The habits we build during Lent are meant to continue throughout the year. Self-control, watchfulness, restraint, generosity, patience—these are not seasonal virtues. They are the marks of a mature Christian life.

Fasting, therefore, is not about proving how strong our body is. It is about forming a soul that is no longer ruled by appetite. When practiced correctly, fasting teaches us that food, comfort, and pleasure are good gifts—but they are not masters.

Christ is.
