"There's nothing magical about fasting" (James Packer). It is self-denial for spiritual reasons. We set our minds on God...and Him alone. Our spiritual hunger must be deep, our determination in intercession intense, and our spiritual warfare demanding. We can win great victories over the powers of darkness through fasting. Isaiah speaks of a proper fast (Isaiah 58:6-8), then he states, "...you will call and the Lord will answer; you will cry and He will say, 'Here I am.'" Fasting offers cleansing and opportune health to the human body. "Many physical and other problems would be solved if Christians would learn to fast in a practical and healthy way," Derek Prince.
