“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.”

“There is no safe investment. To love at all is to be vulnerable. Love anything, and your heart will certainly be wrung and possibly be broken. If you want to make sure of keeping it intact, you must give your heart to no one, not even to an animal. Wrap it carefully round with hobbies and little luxuries; avoid all entanglements; lock it up safe in the casket or coffin of your selfishness. But in that casket – safe, dark, motionless, airless – it will change. It will not be broken; it will become unbreakable, impenetrable, irredeemable. The alternative to tragedy, or at least to the risk of tragedy, is damnation. The only place outside Heaven where you can be perfectly safe from all the dangers and perturbations of love is Hell.”

“Life is too deep for words, so don't try to describe it, just live it. Actually this quote doesn't sound like C.S. Lewis at all. Can anyone provide a source?”

“And as Jill gazed at its motionless bulk, she realized that she might as well have asked the whole mountain to move aside for her convenience.”

“God has not been trying an experiment on my faith or love in order to find out their quality. He knew it already. It was I who didn't. In this trial He makes us occupy the dock, the witness box, and the bench all at once. He always knew that my temple was a house of cards. His only way of making me realize the fact was to knock it down.”

“Perhaps the experience had been so complete that repetition would be vulgarity - like asking to hear the same symphony twice in a day.” 

“[S]omething inside us, the feeling of resentment, the feeling that wants to get one's own back, must be simply killed. I do not mean that anyone can decide this moment that he will never feel it anymore. That is not how things happen. I mean that every time it bobs its head up, day after day, year after year, all our lives long, we must hit it on the head. It is hard work, but the attempt is not impossible.”

“But who is Aslan? Do you know him?" "Well-he knows me," said Edmund. "He is the great Lion, the son of the Emperor-beyond-the-Sea, who saved me and saved Narnia.”

“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.”

“Once a king or queen of Narnia, always a king or queen of Narnia.”

“Don't use words too big for the subject. Don't say infinitely when you mean very; otherwise you'll have no word left when you want to talk about something really infinite.”

“The stamp of the Saint is that he can waive his own rights and obey the Lord Jesus.”

“Be confident small immortals. You are not the only voice that all things utter, nor is there eternal silence in the places where you cannot come.”

“Courage is not simply one of the virtues but the form of every virtue at the testing point, which means at the point of highest reality. ”

“We want not so much a Father but a grandfather in heaven, a God who said of anything we happened to like doing, 'What does it matter so long as they are contented?”
