[To have Faith in Christ] means, of course, trying to do all that He says. There would be no sense in saying you trusted a person if you would not take his advice. Thus if you have really handed yourself over to Him, it must follow that you are trying to obey Him. But trying in a new way, a less worried way. Not doing these things in order to be saved, but because He has begun to save you already. Not hoping to get to Heaven as a reward for your actions, but inevitably wanting to act in a certain way because a first faint gleam of Heaven is already inside you.
C. S. LewisThe notion that everyone would like Christianity to be true, and therefore all atheists are brave men who have accepted the defeat of all their deepest desires, is simply impudent nonsense.
C. S. LewisNow repentance is no fun at all. It is something much harder than merely eating humble pie. It means unlearning all the self-conceit and self-will that we have been training ourselves into for thousands of years. It means undergoing a kind of death. In fact, it needs a good man to repent. And here's the catch. Only a bad person needs to repent: only a good person can repent perfectly. The worse you are the more you need it and the less you can do it. The only person who could do it perfectly would be a perfect person - and he would not need it.
C. S. Lewis
