Fasting, biblically defined, is abstaining from food for spiritual benefit. For most people, fasting ranks right up there with walking barefoot on hot coals, chanting mantras into the night, or taking a bath in goat’s milk. As a child I recall telling my mother that I was “starving” when dinner was an hour late. But skipping dinner altogether? When you don’t even have the flu!?

Many people in our consumptive society lack the insight that sometimes it is better to deny yourself a good thing in order to attain something even better. That’s the case with fasting: by denying ourselves food, we experience a few hunger pangs and a bit of physical weakness in order to grow in intimacy with God and explore new vistas of his truth and grace.

The Purpose of Fasting

Fasting is a biblical practice, not a biblical command. If you have not fasted until now in your Christian life, don’t live in fear that you have been disobeying God. You haven’t.

For most Jews of Jesus’ day, fasting was a common practice, rooted not only in their Bible and commentaries but in their culture as well. The Pharisees fasted twice a week—on Wednesdays and Fridays. In the Sermon on the Mount, Jesus’ phrase “when you fast” (not “if you fast”) shows he assumed this was a regular activity. And though other religious groups criticized him and his disciples for not fasting enough, Jesus predicted that when he—the bridegroom—left the scene, his disciples would fast (Mt 9:15). This last example seems to imply that those of us following Jesus today will participate in the spiritual discipline of fasting.

Jesus felt no obligation to match the self-righteous intensity of the Pharisees when it came to fasting. He saw that their motive was to impress others—perhaps even God—with their display of spirituality. People usually respect such outward signs of commit ment, but God looks deeper. “Was it really for me that you fasted?” he asked the pious Jews of the period following the Babylonian captivity (Zec 7:5). The physical practice of fasting won’t make us more spiritual, but it can open doors that we’ve yet to enter in terms of knowing God and delighting in his presence. As we look now at the host of reasons why we should develop this biblical habit, let’s strike self-righteousness from the list.

Fasting yields insight and understanding from God. Are you confused about something in life? Do you need direction? Are you puzzled by a difficult part of Scripture? Fasting can position you to receive God’s answers to your questions.

Daniel was a man of tremendous influence in Babylon and King Nebuchadnezzar’s wisest counselor. Yet when the prophet read Jeremiah’s prophecy that the Israelites would be in captivity for 70 years (Jer 29:10), he was stumped. So in the ninth chapter of Daniel we find him fasting and asking God for understanding. While in the midst of his prayer, Daniel receives God’s hand-delivered message from the angel Gabriel. “As soon as you began to pray,” said Gabriel, “an answer was given, which I have come to tell you” (Da 9:23).

We can’t expect Gabriel to show up each time we skip lunch, but we can fast with a biblical expectation that God will give us the insight we need.

Fasting helps us master the desires of our flesh. There’s a snack room at my office where I can buy candy bars for only a quarter. Recently I found I had slipped into the habit of visiting the snack room every afternoon at around 2:00 for a little boost to my taste buds and my belly. I wasn’t hungry; lunch was only one hour past. I’d simply taught my body to enjoy that kick of fat and sugar every mid-afternoon. And though my waistline didn’t show the effects, I felt God put his finger on my sweet tooth. So I stopped my afternoon candy breaks. For a while I really missed them, my mind sending that “You’re starving!” message because my body wasn’t getting its food fix.

Candy bars are a minor obsession compared to something like cigarettes, alcohol, or inappropriate sexual excitement. But if through fasting you can learn to sub- due your craving for food, you can gain control over lots of other areas as well.

Paul was determined that nothing other than the gospel of Jesus Christ would master him (1Co 6:12). He disciplined his body so that it would be his slave (1Co 9:27). As fellow servants of Christ, we need to develop the same attitude. If God reveals that we have an undisciplined craving for anything—coffee, nicotine, Diet Coke, or candy bars—we need to show our flesh who is in charge. Fasting is an excellent place to start. This counts for any area of life that needs discipline: control over what goes into our mouths can lead to control over what comes out in the form of anger, gossip, or boasting.

Fasting humbles our souls. Just before the Israelites crossed the Jordan into the Promised Land, Moses reminded them of what they had learned in the wilderness: “Remember how the Lord your God led you all the way in the desert these forty years, to humble you and to test you...He humbled you, causing you to hunger and then feeding you with manna, which neither you nor your fathers 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” (Dt 8:2,3). But the Israelites quickly forgot. Once they entered Canaan, a land “flowing with milk and honey,” they strayed from their dependence on God.

When life is comfortable and we have everything we want—good food, a nice place to live, financial security—it’s easy to forget the One who has given us such blessings. We’re prone to say, as Moses warned the Israelites, “My power and the strength of my hands have produced this wealth for me” (Dt 8:17). Fasting is a great way to clear our minds of that delusion. Fasting takes away our sense of independence and lets us experience our powerlessness before the Lord.

In Psalm 35, David says, “[I] humbled myself with fasting” (v.13). When I fast, I feel weak. It sometimes feels like I’ve chosen a day of self-imposed sickness. I’ve never begun a period of fasting thinking, “Oh, this is great! No food for a whole day!” Sometimes I get headaches, and on fasts of more than a day I can get dizzy if I stand up too fast. Twenty four hours of fasting makes me weak and tired. But it’s a weakness that I highly value because it reminds me of my absolute dependence on God and his mercy. It is this heightened sense of dependence that I consider to be the most valuable result of fasting.

Fasting prepares us for challenging tasks. At different points in biblical history we find people fasting in anticipation of a significant challenge. Ezra was one of the leaders who brought the Jews back from Babylon to rebuild Jerusalem. Before setting out on the long, dangerous journey he called a corporate fast to ask God’s protection (Eze 8:21-23). Jesus launched his public ministry with a 40-day fast (Mt 4:1-3). This time also equipped him to face the incredibly attractive propositions of Satan. Paul and Barnabas received confirmation of their sense of call to apostolic ministry during a time of worship and fasting (Ac 13:2-3).

Are you facing a significant or difficult decision? Is there a crisis in your life? Do you need grace for the week of vacation you’ll be spending with non-Christian relatives? Whether the challenge is spiritual or secular, consider preparing yourself with a fast.

Fasting sensitizes us to poverty and injustice. The Jews in Isaiah’s day exhibited all the outward signs of righteousness. But God revealed through the prophet that their fasting and religious zeal was hypocritical. Why? Because it didn’t affect their hearts. “On the day of your fasting, you do as you please and exploit all your workers. Your fasting ends in quarreling and strife, and in striking each other with wicked fists” (Is 58:3,4).

Throughout Isaiah 58, God calls for a fast that goes beyond ceremony. “Is not this the kind of fasting I have chosen: to loose the chains of injustice and untie the cords of the yoke, to set the oppressed free and break every yoke?” (v.6) A fast should make us more aware of God and more aware of those around us. If we keep our eyes and hearts open, God will reveal human needs whereby the spiritual discipline of fasting can spill over into physical benefits as well.

Fasting aids us in intercession. The prophet Jeremiah recorded this promise from God: “Then you will call upon me and come and pray to me, and I will listen to you. You will seek me and find me when you seek me with all your heart” (Jer 29:12-13, emphasis added). Fasting is an expression of wholehearted zeal, as we find in the book of Joel: “‘Even now,’ declares the Lord, ‘return to me with all your heart, with fasting and weeping and mourning’” (Joel 2:12). This may be a reason why we don’t sense God’s help or direction in our trials. He’s looking for fervent searching—a searching that is greatly aided by fasting.

Fasting adds muscle to our spiritual warfare. When Jesus sought spiritual power to withstand the devil and accomplish God’s purpose, he fasted. The Bible describes countless individuals and even entire nations who gave up their food to change the course of history by fervent intercession.

Some Practical Guidelines

Types of fasts. Scripture indicates several different ways to fast:

The normal fast. When I first experimented with fasting, I thought I had to give up everything. I was into the second day when my aunt asked, “Are you drinking any water?” “No,” I answered, “I’m fasting.” She proceeded to set me straight and spare me from dehydration.

A normal fast excludes food but includes water. At the end of Jesus’ 40-day fast, Scripture says he was hungry (Mt 4:2). Had he not drunk water during that time, apart from supernatural intervention not indicated in the text, his body wouldn’t have made it. In Scripture, absolute fasts are a rare exception. Both Esther and Paul went three days without food or water (Est 4:16, Ac 9:9), but their situations were desperate. An absolute fast should be clearly directed by God and should never exceed three days.

The partial fast. After a particularly disturbing vision, Daniel spent three weeks on a “luxury free” diet. As he describes it, “I ate no choice food; no meat or wine touched my lips; and I used no lotions at all until the three weeks were over” (Da 10:3). If your work schedule is so demanding that you can’t cope without food, consider something along the lines of Daniel’s model. A juice fast, for example, is completely acceptable, though you should avoid anything high in refined sugar as well as citrus juices (unless they are fresh).

God doesn’t evaluate our fasting by the length or totality of our abstinence from food. He cares only for its effect on our hearts. If a partial fast works well with your schedule and accomplishes God’s purpose, don’t let anyone tell you it’s insufficient.

The corporate fast. It’s a little-known fact that Abraham Lincoln designated April 30, 1863 as “a day of national humiliation, fasting and prayer.” He did this at two other times during his presidency; before him, Presidents John Adams and James Madison had done the same. In each case the nation sought God’s help as it faced the prospect of war.

Corporate fasting results in multiplied power. Jesus said, “For where two or three come together in my name, there am I with them” (Mt 18:20). Churches and nations can expect an outpouring of God’s power and grace when they band together in properly motivated fasting and prayer. Throughout the Old and New Testaments we see God’s people feasting and fasting corporately, as noted above in the case of Paul and Barnabas in Acts 13.

Planning ahead. The main value of fasting lies not in its ability to impress God, but in the way it sensitizes us to him. Our hunger has no inherent benefit unless it brings us to our knees before God. So don’t fast just for the sake of fasting. Enter your fast with a strategy for how you will spend the time and what you hope to accomplish. This will reinforce your motivation and sharpen your concentration. Also, don’t make the mistake of gorging yourself before a fast—it just makes withdrawal from food all the more difficult. It’s best to make your last meal a light one, especially if you intend to fast longer than 24 hours.

If you have a medical condition like diabetes, check with your doctor before fasting. The same would apply for pregnant or nursing women.

The importance of prayer. Even if you can’t set aside time for concentrated prayer, fasting has value as a means of dedication and consecration to the Lord. However, I benefit most from fasting when I take time to make prayer a priority. At the very least, take the time you’d normally spend eating to feast on communication with your Father. Let’s take advantage of this time when our spiritual senses can be sharpest.

Working your way up. If you have never fasted, don’t think you need to begin with 40 days alone in the desert. A horrible first experience will make it hard for you to consider fasting again. Instead, consider the following progression:

24-hour juice fast. Begin in the evening (after dinner) by consecrating the time to God in prayer. During the following day, drink juice and pray in lieu of breakfast and lunch. Conclude by eating dinner.

24-hour water fast. Same as the above, but drink water instead of juice. You’ll find yourself weaker, but you should be able to miss two meals without any significant effect on your work.

36-hour water fast. By skipping your evening meal you can add 12 hours to your time of fasting. It doesn’t matter whether dinner is the first meal or the last meal you miss. The schedule isn’t important. Experiment to find what makes your times of fasting most fruitful.

Three-day water fast. I try to schedule this type of extended fast at a time in my calendar when God can do a complete spiritual check-up. Some may do this routinely; others may consider a three-day fast as intimidating as running a marathon. If you’re in that second category, this story may encourage you.

Years ago I had a friend who, after hearing that I was going on a three-day retreat to fast and pray, gave me a look of horror. His religious background made him suspect I was doing this out of some legalistic obligation. He found it nearly impossible to understand why anyone would choose to subject himself to such extended torture voluntarily.

I gave him the chance to find out when I invited him to join me. To our mutual surprise, he came along. And while I spent much of my time fighting headaches and aching muscles (for some reason it was a difficult fast for me), he tooled along as if nothing were wrong, barely feeling the effects.

Typical side effects. If you’re unwilling to experience some discomfort, you’re not properly prepared to fast. Disciplining our flesh has a price tag attached. But the benefit you’ll receive easily outweighs the symptoms that accompany fasting:

Headaches. This may be your body’s way of complaining about caffeine withdrawal, or perhaps you’re not drinking enough water.

Drowsiness. As your blood sugar levels drop, so does your energy. One time when I was fasting during an unseasonably warm late winter day I lay back in the grass of an open field to pray. I woke up an hour later. Though initially I felt guilty, I realized this was just part of the program. Fasting reminds me how weak I really am.
