“The Christian is in a different position from other people who are trying to be good. They hope, by being good, to please God if there is one; or — if they think there is not — at least they hope to deserve approval from good men. But the Christian thinks any good he does comes from the Christ-life inside him. He does not think God will love us because we are good, but that God will make us good because He loves us; just as the roof of a greenhouse does not attract the sun because it is bright, but becomes bright because the sun shines on it.”
― C.S. Lewis, Mere Christianity

“In the same way a Christian is not a man who never goes wrong, but a man is enabled to repent and pick himself up and begin over again after each stumble--because the Christ-life is inside him, repairing him all the time, enabling him to repeat (in some degree) the kind of voluntary death which Christ Himself carried out." - Mere Christianity”
