By: St. Gregory Palamas
Sensual pleasure causes ungodliness as well as sin, but fasting and self-control result in the fear of God as well as virtue. Fasting must be accompanied by self-control. Why? Because eating our fill, even of humble foods, is a hindrance to the purifying mourning, godly sorrow and contrition in our souls, which bring about unswerving repentance leading to salvation. For without a contrite heart we cannot really lay hold of repentance. It is the restriction of self-indulgence, sleep and the senses according to God’s will that crushes our hearts and makes us mourn for our sins.
