A Commonsense Guide to Fasting by Kenneth E. Hagin
In all the Epistles—the books of the New Testament written to the Church—not one time is the Church told to fast. That doesn’t mean we should not. Mention is made of fasting, but no rules are laid down, nor is the Church even encouraged to fast. The reason is, fasting is to be done as the occasion arises. Fasting does not change God. He is the same before, during, and after you fast. But fasting will change you. It will help you keep the flesh under. It will help you become more sensitive to the Spirit of God.
