There is renewed power through prayer and fasting because we are reminded that ultimately we are dependent on God. Prayer and fasting humble us. This self-denial of our exaggerated physical appetite, for a period of time, allows us to wait in faith and to trust God’s mercy. Prayer and fasting are signs of our desire and hunger to seek God. And in seeking Him, we place less importance on our daily routines of finding food and momentary physical pleasures. Through prayer and fasting, we develop a passion for God that supersedes everything else. When this happens, spiritual power and energy begin to flow into us, allowing us to live above our circumstances and low self-expectations.
The Fathers of the church teach that the external fast is necessary from time to time for spiritual renewal. But the internal fast is necessary at all times.
Archbishop Frank Simon said: “There are three things, my brethren, by which faith stands firm, devotion remains constant, and virtue endures. They are prayer, fasting and mercy. Prayer knocks at the door; fasting obtains; mercy receives. Prayer, fasting and mercy- These three are one and they give life to each other.”
