“If we consider the unblushing promises of reward … promised in the Gospels, it would seem that our Lord finds our desires not too strong, but too weak. We are half-hearted creatures, fooling about with drink and sex and ambition when infinite joy is offered us, like an ignorant child who wants to go on making mud pies in a slum because he cannot imagine what is meant by the offer of a holiday at sea. We are far too easily pleased.”

“The human heart is not unchanging (nay, changes almost out of recognition in the twinkling of an eye)...”

“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.”

“Here the whole world (stars, water, air, And field, and forest, as they were Reflected in a single mind) Like cast off clothes was left behind In ashes, yet with hopes that she, Re-born from holy poverty, In lenten lands, hereafter may Resume them on her Easter Day."

“God has no needs. Human love, as Plato teaches us, is the child of Poverty – of want or lack; it is caused by a real or supposed goal in its beloved which the lover needs and desires. But God's love, far from being caused by goodness in the object, causes all the goodness which the object has, loving it first into existence, and then into real, though derivative, lovability. God is Goodness. He can give good, but cannot need or get it. In that sense , His love is, as it were, bottomlessly selfless by very definition; it has everything to give, and nothing to receive.”

“The sin both of men and of angels, was rendered possible by the fact that God gave us free will.”

“Our experience is coloured through and through by books and plays and the cinema, and it takes patience and skill to disentangle the things we have really learned from life for ourselves.”

“The laws of the universe are never broken. Your mistake is to think that the little regularities we have observed on one planet for a few hundred years are the real unbreakable laws; whereas they are only the remote results which the true laws bring about more often than not; as a kind of accident.”

“A silly idea is current that good people do not know what temptation means. This is an obvious lie. Only those who try to resist temptation know how strong it is... A man who gives in to temptation after five minutes simply does not know what it would have been like an hour later. That is why bad people, in one sense, know very little about badness. They have lived a sheltered life by always giving in.”

“If conversion to Christianity makes no improvement in a man's outward actions – if he continues to be just a snobbish or spiteful or envious or ambitious as he was before – then I think we must suspect that his 'conversion' was largely imaginary; and after one's original conversion, every time one thinks one has made an advance, that is the test to apply. Fine feelings, new insights, greater interest in 'religion' mean nothing unless they make our actual behavior better; just as in an illness 'feeling better' is not much good if the thermometer shows that your temperature is still going up. In that sense the outer world is quite right to judge Christianity by its results. Christ told us to judge by results. A tree is known by its fruit; or, as we say, the proof of the pudding is in the eating. When we Christians behave badly, or fail to behave well, we are making Christianity unbelievable to the outside world. The war-time posters told us that Careless Talk costs Lives. It is equally true that Careless Lives cost Talk. Our careless lives set the outer world taking; and we give them grounds for talking in a way that throws doubt on the truth of Christianity itself.”

“Then two wonders happened at the same moment. One was that the voice was suddenly joined by other voices; more voices than you could possibly count. They were in harmony with it, but far higher up the scale: cold, tingling, silvery voices. The second wonder was that the blackness overhead, all at once, was blazing with stars. They didn’t come out gently one by one, as they do on a summer evening. One moment there had been nothing but darkness; next moment a thousand, thousand points of light leaped out – single stars, constellations, and planets, brighter and bigger than any in our world. There were no clouds. The new stars and the new voices began at exactly the same time. If you had seen and heard it, as Digory did, you would have felt quite certain that it was the stars themselves which were singing, and that it was the First Voice, the deep one, which had made them appear and made them sing.”

“Nothing is very strong: strong enough to steal away a man's best years not in sweet sins but in a dreary flickering of the mind over it knows not what and knows not why, in the gratification of curiosities so feeble that the man is only half aware of them, in drumming of fingers and kicking of heels, in whistling tunes that he does not like, or in the long, dim labyrinth of reveries that have not even lust or ambition to give them a relish, but which, once chance association has started them, the creature is took weak and fuddled to shake off.”

“Good and evil both increase at compound interest. That is why the little decisions you and I make every day are of such infinite importance. The smallest good act today is the capture of a strategic point from which, a few months later, you may be able to go on to victories you never dreamed of. An apparently trivial indulgence in lust or anger today is the loss of a ridge or railway line or bridgehead from which the enemy may launch an attack otherwise impossible.”

“If they won't write the kind of books we like to read we shall have to write them ourselves.”

“You can’t go on “seeing through” things forever. The whole point of seeing through something is to see something through it. To “see through” all things is the same as not to see.”
