In recognition of the 106th anniversary of the birth of C. S. Lewis, here is an exerpt from his classic, Mere Christianity. (For those of you who are fans of the band "Sixpence None the Richer", this is source of their name.)
"Every faculty you have, your power of thinking or of moving your limbs from moment to moment, is given to you by God. If you devoted every moment of your whole life exclusively to His service you could not give Him anything that was not in a sense His own already. So that when we talk of a man doing anything for God or giving anything to God, I will tell you what it is really like. It is like a small child going to its father and saying, 'Daddy, give me sixpence to buy you a birthday present.' Of course, the father does, and he is pleased with the child's present. It is all very nice and proper, but only an idiot would think that the father is sixpence to the good on the transaction. When a man has made these two discoveries, God can really get to work. It is after this that real life begins. The man is awake now."
