A man can eat his dinner without understanding exactly how food nourishes him. A man can accept what Christ has done without knowing how it works: indeed, he certainly would not know how it works until he has accepted it.
C. S. LewisThere is a difficulty about disagreeing with God. He is the source from which all your reasoning power comes: you could not be right and he wrong any more than a stream can rise higher than its own source. When you are arguing against Him you are arguing against the very power that makes you able to argue at all: it is like cutting off the branch you are sitting on.
C. S. LewisThe Christian life is simply a process of having your natural self changed into a Christ self, and that this process goes on very far inside. One's most private wishes, one's point of view, are the things that have to be changed.
C. S. LewisOur merriment must be of that kind (and it is, in fact, the merriest kind) which exists between people who have, from the outset, taken each other seriously - no flippancy, no superiority, no presumption. And our charity must be a real and costly love, with deep feeling for the sins in spite of which we love the sinner - no mere tolerance or indulgence which parodies love as flippancy parodies merriment.
C. S. Lewis
