Fasting has been a common practice in every age and among every nation. Hagin gives long overdue insights from the Old and New Testaments into this subject. He explains that "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." Readers will discover the proper length of a fast, alternatives to the traditional view of fasting, and Hagin's own personal alternatives.
