Taylor Halverson: Why Do We Fast?


This article originally appeared on and is republished here with permission.

When I was a kid, I hated fast Sunday. It seemed like the slowest day of the entire month. Why would anyone call “fast” a day when we didn’t eat? That monthly day seemed to stretch until the Millennium. I felt that God must have found sound strange delight in causing such enduring suffering to my famishing stomach.

My mind could do nothing, it seemed, except think about all the foods that I craved. I would fantasize about consuming juicy cheeseburgers, devouring heapings of pizza, draining liters of root beer, and scarfing away a baker’s dozen of donuts.

My mental habits did not help me well-endure or experience the meaningfully and divine purposes of fasting.

Only years later with persistent effort did I come to understand in my heart, mind, and importantly, in my body, the why of fasting.

This understanding is underscored by the meaning of the word "fast." But before I explain the meaning of the word, let me briefly illustrate the concept.

Selective Denial Makes Us Stronger

There once was a young man who aspired to be a competitive swimmer. One of the things that he needed to develop in order to compete was deeper lung capacity and the ability to hold his breath underwater.

The struggle was real. There he was in the water exercising his body, his lungs screaming for air. And yet to get stronger, he needed to slowly build up his lung capacity by selectively denying himself air for short periods of time at first, and then over a period of days and weeks building up to denying himself air for longer periods of time.

He continued to exercise and practice deep breathing exercises. After many days, weeks, and months, the muscles in his body strengthened. His lung capacity grew. The efficiency of his breathing increased.

By denying himself, he gained more.

By saying "no," he got to "yes."

As his body strengthened, as his capacity matured, and as he grew and developed by selectively denying himself, he was able to successfully compete at a high level. But more importantly, because of his sacrifice, he became something more than what he had started as.

That is the essence of the fast. When we fast, we are denying ourselves for a time with the ultimate outcome that we are strengthened.

To Fast Is to Become Strong, Firm, Steadfast

When we hear the word fast, we often think of "quick," or "quickly." That was my teenage understanding. I thought that Fast Sunday was supposed to pass quickly by.

But that is not the original or core meaning of "fast."

The basic and fundamental meaning of "fast" is "strong."

Consider this. Someone who runs fast, or quickly, is a strong runner. When we fasten things together, we bind them strongly. A fastener makes things stronger.

Therefore, to fast is to become strong!

The word fast also means “to be fortified, to make firm, to pledge, to establish, to confirm, to make strong, to make solid, to hold firmly, to have firm control of oneself, to keep, and to observe” and in the far ancient past “a dwelling place.” Learn more about the origin and etymology of "fast" here.

As we join with others in a worldwide fast, let us remember that this is a beautiful invitation to strengthen our spirits, grow firm in our knowledge of God’s love, pledge ourselves to God and His service, and to be fortified.
