“Badness is only spoiled goodness.”

“You never know how much you really believe anything until its truth of falsehood becomes a matter of life and death to you. It is easy to say you believe a rope to be strong and sound as long as you are merely using it to cord a box. But suppose you had to hang by that rope over a precipice. Wouldn't you then first discover how much you really trusted it?”

“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”

“Look for the valleys, the green places, and fly through them. There will always be a way through.”

“Do not cite the Deep Magic to me, Witch. I was there when it was written.”

“Hell is a state of mind - ye never said a truer word. And every state of mind, left to itself, every shutting up of the creature within the dungeon of its own mind - is, in the end, Hell. But Heaven is not a state of mind. Heaven is reality itself. All that is fully real is Heavenly. For all that can be shaken will be shaken and only the unshakeable remains.”

“God created things which had free will. That means creatures which can go wrong or right. Some people think they can imagine a creature which was free but had no possibility of going wrong, but I can't. If a thing is free to be good it's also free to be bad. And free will is what has made evil possible. Why, then, did God give them free will? Because free will, though it makes evil possible, is also the only thing that makes possible any love or goodness or joy worth having. A world of automata -of creatures that worked like machines- would hardly be worth creating. The happiness which God designs for His higher creatures is the happiness of being freely, voluntarily united to Him and to each other in an ecstasy of love and delight compared with which the most rapturous love between a man and a woman on this earth is mere milk and water. And for that they've got to be free. Of course God knew what would happen if they used their freedom the wrong way: apparently, He thought it worth the risk. (...) If God thinks this state of war in the universe a price worth paying for free will -that is, for making a real world in which creatures can do real good or harm and something of real importance can happen, instead of a toy world which only moves when He pulls the strings- then we may take it it is worth paying.”

“The truest and most horrible claim made for modern transport is that it “annihilates space.” It does. It annihilates one of the most glorious gifts we have been given. It is a vile inflation which lowers the value of distance, so that a modern boy travels a hundred miles with less sense of liberation and pilgrimage and adventure than his grandfather got from traveling ten. Of course if a man hates space and wants it to be annihilated, that is another matter. Why not creep into his coffin at once? There is little enough space there.”

“We read to know we are not alone.”

“[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.”

“Do not dare not to dare.”

“In Science we have been reading only the notes to a poem; in Christianity we find the poem itself.”

“If you are a Christian you do not have to believe that all the other religions are simply wrong all through. If you are an atheist you do have to believe that the main point in all the religions of the whole world is simply one huge mistake.”

“As to...old composers like Schubert or Beethoven, I imagine that, while modern music expresses both feeling, thought and imagination, they expressed pure feeling. And you know all day sitting at work, eating, walking, etc., you have hundreds of feelings that can't be put into words. And that is why I think that in a sense music is the highest of the arts, because it really begins where the others leave off.” 

“When you argue 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.”
