“Christianity, if false, is of no importance, and if true, of infinite importance, the only thing it cannot be is moderately important.”

“Good and evil both increase at compound interest.”

“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.”

“As he rose to his feet he noticed that he was neither dripping nor panting for breath as anyone would expect after being under water. His clothes were perfectly dry. He was standing by the edge of a small pool—not more than ten feet from side to side in a wood. The trees grew close together and were so leafy that he could get no glimpse of the sky. All the light was green light that came through the leaves: but there must have been a very strong sun overhead, for this green daylight was bright and warm. It was the quietest wood you could possibly imagine. There were no birds, no insects, no animals, and no wind. You could almost feel the trees growing. The pool he had just got out of was not the only pool. There were dozens of others—a pool every few yards as far as his eyes could reach. You could almost feel the trees drinking the water up with their roots. This wood was very much alive.”

“The humans live in time but our Enemy (God) destines them for eternity.”

“Well, you know how it feels if you begin hoping for something that you want desperately badly; you almost fight against the hope because it is too good to be true; you've been disappointed so often before.”

“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. ”

“The settled happiness and security which we all desire, God withholds from us by the very nature of the world: but joy, pleasure, and merriment, He has scattered broadcast. We are never safe, but we have plenty of fun, and some ecstasy. It is not hard to see why. The security we crave would teach us to rest our hearts in this world and oppose an obstacle to our return to God: a few moments of happy love, a landscape, a symphony, a merry meeting with out friends, a bathe or a football match, have no such tendency. Our Father refreshes us on the journey with some pleasant inns, but will not encourage us to mistake them for home.”

“Enemy-occupied territory---that is what this world is. Christianity is the story of how the rightful king has landed, you might say landed in disguise, and is calling us to take part in a great campaign of sabotage.”

“Be not deceived, Wormwood, our cause is never more in jeopardy than when a human, no longer desiring but still intending to do our Enemy's will, looks round upon a universe in which every trace of Him seems to have vanished, and asks why he has been forsaken, and still obeys.”

“I am a product of long corridors, empty sunlit rooms, upstairs indoor silences, attics explored in solitude, distant noises of gurgling cisterns and pipes, and the noise of wind under the tiles. Also, of endless books.”

“All mortals tend to turn into the thing they are pretending to be. This is elementary”

“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 pain I feel now is the happiness I had before. That's the deal.”

“The love of knowledge is a kind of madness.”
