"God made us: invented us as a man invents an engine. A car is made to run on gasoline, and it would not run properly on anything else. Now God designed the human machine to run on Himself. He Himself is the fuel our spirits were designed to burn, or the food our spirits were designed to feed on. God cannot give us a happiness and peace apart from Himself, because it is not there. There is no such thing." (C. S. Lewis - Mere Christianity. Macmillan Publishing. 1978. pg. 54)
