“Don't let your happiness depend on something you may lose.” 

“In our adversity, God shouts to us.”

“Well, sir, if things are real, they’re there all the time." "Are they?" said the Professor; and Peter did not quite know what to say.”

“Spiteful words can hurt your feelings but silence breaks your heart.”

“He liked books if they were books of information and had pictures of grain elevators or of fat foreign children doing exercises in model schools.”

“You will never make a good impression on other people until you stop thinking about what sort of impression you are making. Even in literature and art, no man who bothers about originality will ever be original: whereas if you simply try to tell the truth (without caring twopence how often it has been told before) you will, nine times out of ten, become original without ever having noticed it... Give up yourself, and you will find your real self.”

“The great thing to remember is that though our feelings come and go God's love for us does not.” 

“Notice how we are perpetually surprised at Time. ('How time flies! Fancy John being grown-up and married! I can hardly believe it!') In heavens name, why? Unless, indeed, there is something in us which is not temporal.”

“If we insist on keeping Hell (or even earth) we shall not see Heaven: if we accept Heaven we shall not be able to retain even the smallest and most intimate souvenirs of Hell.”

“It is much easier to pray for a bore than to go visit him.”

“You can’t see anything properly while your eyes are blurred with tears. You can’t, in most things, get what you want if you want it too desperately: anyway, you can’t get the best out of it.”

“One word, Ma'am," he said, coming back from the fire; limping, because of the pain. "One word. All you've been saying is quite right, I shouldn't wonder. I'm a chap who always liked to know the worst and then put the best face I can on it. So I won't deny any of what you said. But there's one more thing to be said, even so. Suppose we have only dreamed, or made up, all those things-trees and grass and sun and moon and stars and Aslan himself. Suppose we have. Then all I can say is that, in that case, the made-up things seem a good deal more important than the real ones. Suppose this black pit of a kingdom of yours is the only world. Well, it strikes me as a pretty poor one. And that's a funny thing, when you come to think of it. We're just babies making up a game, if you're right. But four babies playing a game can make a play-world which licks your real world hollow. That's why I'm going to stand by the play world. I'm on Aslan's side even if there isn't any Aslan to lead it. I'm going to live as like a Narnian as I can even if there isn't any Narnia. So, thanking you kindly for our supper, if these two gentlemen and the young lady are ready, we're leaving your court at once and setting out in the dark to spend our lives looking for Overland. Not that our lives will be very long, I should think; but that's a small loss if the world's as dull a place as you say.”

“[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.”

“Love, in its own nature, demands the perfecting of the beloved.”

“This act [creation], as it is for God, must always remain totally inconceivable to man. For we--even our poets and musicians and inventors--never, in the ultimate sense make. We only build. We always have materials to build from. All we can know about the act of creation must be derived from what we can gather about the relation of the creatures to their Creator”
