Donโt resist the suffering that accompanies fasting. It's a spiritual exercise that God honors. He promises to heap blessings on people who are hungry for Him. Fasting is primarily a spiritual practice to be closer in union with God, a recognition of our dependence on Him.The practice of fasting is essentially giving up food/drink/worldly activities for a period of time in order to better focus your thoughts and attention on God, by praying and reading the Bible.
