Through His incarnation God gave us the model for a holy life and recalled us from our ancient fall. In addition to many other things. He taught us, feeble as we are, that we should fight against the demons with humility, fasting, prayer and watchfulness. For when, after His baptism. He went into the desert and the devil came up to Him as though He were merely a man, He began His spiritual warfare by fasting and won the battle by this means -though, being God, and God of gods. He had no need of any such means at all.
St. Hesychios the Priest
