The Principles of Biblical Fasting.
There are two main overriding principles related to prayer and fasting in the Bible.
First, biblical fasting is going without food. The noun translated “fast” or “a fasting” is tsom in the Hebrew and nesteia in the Greek language. It means the voluntary abstinence from food. The literal Hebrew translation would be “not to eat.” The literal Greek means “no food.”
I know people who say they go without television or movies, and they call these “fasting” times. I’m not opposed to that definition of fasting-fasting does imply that we are giving up one thing in order to replace it with something else, and in the Bible sense, specifically to replace it with prayer. But in the main, I believe fasting has to do with our abstaining from food. Second, biblical fasting is linked with serious seasons of prayer. The more seriously we approach prayer and fasting, the more serious the results we will experience.
I sometimes hear people say, “I’m giving up chocolate” and they regard this as a type of fasting. I think this is a rather frivolous approach. The first and foremost purpose of a biblical or spiritual fast is to get a breakthrough on a particular matter that one lifts up to the Lord in prayer. A spiritual fast involves our hearts and the way in which we relate to and trust God. It relates to discerning and receiving strength to follow through on what God might reveal to us about circumstances in our lives or a direction we are to take.
I am not against people fasting in order to lose weight. Many people fast to lose weight or maintain their weight.What I am opposed to is making the losing of weight your primary goal in a season of spiritual fasting and prayer. To have weight loss as a goal makes your fasting a diet plan, not a time of genuine fasting and prayer. If losing weight is your purpose in fasting, you will be missing out on the full reason for fasting, and you likely will be concerned only with what you don’t eat rather than with what you are led to pray.
Now there’s certainly an issue of food that is associated with many seasons of prayer and fasting, and let me quickly add this: control of eating is a valid reason to fast. The purpose is not the number of pounds you might lose during a fast, but rather, trusting God to help you regain mastery over food during a fast. Jesus said, “The spirit is . . . willing, but the flesh is weak” (Matt. 26:41). Fasting is a means of bringing the flesh into submission to the Lord so He can strengthen us in our mastery over our own selves. Fasting in the flesh makes us stronger to stand against the temptations of the flesh. Those temptations very often deal with food.
Abstaining from food is often God’s way of showing that His desire for us is that we regain mastery over all things associated with our flesh in order to subdue our flesh and elevate our emphasis on spiritual matters. God’s promise is to help us as we overcome the flesh and put all carnal temptations into subjection.
