“...My idea of God is a not divine idea. It has to be shattered from time to time. He shatters it Himself. He is the great iconoclast. Could we not almost say that this shattering is one of the marks of His presence?..”

“I do not think there is a demonstrative proof (like Euclid) of Christianity, nor of the existence of matter, nor of the good will and honesty of my best and oldest friends. I think all three are (except perhaps the second) far more probable than the alternatives. The case for Christianity in general is well given by Chesterton…As to why God doesn't make it demonstratively clear; are we sure that He is even interested in the kind of Theism which would be a compelled logical assent to a conclusive argument? Are we interested in it in personal matters? I demand from my friend trust in my good faith which is certain without demonstrative proof. It wouldn't be confidence at all if he waited for rigorous proof. Hang it all, the very fairy-tales embody the truth. Othello believed in Desdemona's innocence when it was proved: but that was too late. Lear believed in Cordelia's love when it was proved: but that was too late. 'His praise is lost who stays till all commend.' The magnanimity, the generosity which will trust on a reasonable probability, is required of us. But supposing one believed and was wrong after all? Why, then you would have paid the universe a compliment it doesn't deserve. Your error would even so be more interesting and important than the reality. And yet how could that be? How could an idiotic universe have produced creatures whose mere dreams are so much stronger, better, subtler than itself?”

“I’d rather be killed fighting for Narnia than grow old and stupid at home and perhaps go about in a bath-chair and then die in the end just the same.”

“Once very near the end I said, 'If you can -- if it is allowed -- come to me when I too am on my death bed.' 'Allowed!' she said. 'Heaven would have a job to hold me; and as for Hell, I'd break it into bits.”

“100 per cent of us die, and the percentage cannot be increased. ”

“I think all Christians would agree with me if I said that though Christianity seems at first to be all about morality, all about duties and rules and guilt and virtue, yet it leads you on, out of all that, into something beyond. One has a glimpse of a country where they do not talk of those things, except perhaps as a joke. Everyone there is filled full with what we should call goodness as a mirror is filled with light. But they do not call it goodness. They do not call it anything. They are not thinking of it. They are too busy looking at the source from which it comes. But this is near the stage where the road passes over the rim of our world. No one's eyes can see very far beyond that: lots of people's eyes can see further than mine.” 

“And he writhed inside at what seemed the cruelty and unfairness of the demand. He had not yet learned that if you do one good deed your reward usually is to do another and harder and better one.”

“Can a mortal ask questions which God finds unanswerable? Quite easily, I should think. All nonsense questions are unanswerable. How many hours are in a mile? Is yellow square or round? Probably half the questions we ask - half our great theological and metaphysical problems - are like that.”

“Though under earth, and throneless now I be Yet while I lived all earth was under me.”

“I am a product [...of] endless books. My father bought all the books he read and never got rid of any of them. There were books in the study, books in the drawing room, books in the cloakroom, books (two deep) in the great bookcase on the landing, books in a bedroom, books piled as high as my shoulder in the cistern attic, books of all kinds reflecting every transient stage of my parents' interest, books readable and unreadable, books suitable for a child and books most emphatically not. Nothing was forbidden me. In the seemingly endless rainy afternoons I took volume after volume from the shelves. I had always the same certainty of finding a book that was new to me as a man who walks into a field has of finding a new blade of grass.”

“If you asked twenty good men to-day what they thought the highest of the virtues, nineteen of them would reply, Unselfishness. But if you asked almost any of the great Christians of old he would have replied, Love - You see what has happened? A negative term has been substituted for a positive, and this is of more than philological importance.  The negative ideal of Unselfishness carries with it the suggestion not primarily of securing good things for others, but of going without them ourselves, as if our abstinence and not their happiness was the important point.”

“Welcome, Prince,' said Aslan. 'Do you feel yourself sufficient to take up the Kingship of Narnia?' I - I don't think I do, Sir,' said Caspian. 'I am only a kid.' Good,' said Aslan. 'If you had felt yourself sufficient, it would have been proof that you were not.”

“[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.”

“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?”

“Has this world been so kind to you that you should leave with regret? There are better things ahead than any we leave behind.”
