Talking about gluttony on a food blog? I'm funny - right?!
"Self-indulgence is the enemy of gratitude, and self-discipline usually its friend and generator. That is why gluttony is a deadly sin. The early desert fathers believed that a person's appetites are linked: full stomachs and jaded palates take the edge from our hunger and thirst for righteousness. They spoil the appetite for God."
As found in Dr. Donald Whitney's book Spiritual Disciplines for the Christian Life (p 151)
