Fasting is the most powerful spiritual discipline of all the Christian disciplines. Through fasting and prayer, the Holy Spirit can transform your life. Fasting is mentioned over 100 times in the Old and New Testaments, and has been practiced by almost every notable saint throughout history; yet it is practically unknown in our churches today. Even finding a guide on how to fast is difficult. With that in mind, Dr. George Crabb thoroughly explains the physical and spiritual benefits of fasting from a medical and biblical viewpoint. He explains how our current world needs Christians to fast, and the Satanic tendency of some modern Bible versions to remove fasting from the Christian’s vocabulary.
