“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.”

“I ended my first book with the words 'no answer.' I know now, Lord, why you utter no answer. You are yourself the answer. Before your face questions die away. What other answer would suffice? Only words, words; to be led out to battle against other words.”

“Crying is all right in its way while it lasts. But you have to stop sooner or later, and then you still have to decide what to do.”

“Friendship is the greatest of worldly goods. Certainly to me it is the chief happiness of life. If I had to give a piece of advice to a young man about a place to live, I think I should say, 'sacrifice almost everything to live where you can be near your friends.” 

“Mortal lovers must not try to remain at the first step; for lasting passion is the dream of a harlot and from it we wake in despair.”

“A proud man is always looking down on things and people; and, of course, as long as you are looking down, you cannot see something that is above you.”

“The sane would do no good if they made themselves mad to help madmen.”

“Don't shine so others can see you. Shine so that through you, others can see Him.”

“Suppose that the earthly lives she and I shared for a few years are in reality only the basis for, or prelude to, or earthly appearance of, two unimaginable, supercosmic, eternal somethings.”

“God can't give us peace and happiness apart from Himself because there is no such thing.”

“God is the only comfort, He is also the supreme terror: the thing we most need and the thing we most want to hide from. He is our only possible ally, and we have made ourselves His enemies. Some people talk as if meeting the gaze of absolute goodness would be fun. They need to think again. They are still only playing with religion. Goodness is either the great safety or the great danger - according to the way you react to it. And we have reacted the wrong way.”

“Thirst was made for water; inquiry for truth”

“You do not see as quite as well as you think.”

“When the author walks onto the stage, the play is over”

“All this is flashy rhetoric about loving you. I never had a selfless thought since I was born. I am mercenary and self-seeking through and through: I want God, you, all friends, merely to serve my turn. Peace, re-assurance, pleasure, are the goals I seek, I cannot crawl one inch outside my proper skin: I talk of love --a scholar's parrot may talk Greek-- But, self-imprisoned, always end where I begin. Only that now you have taught me (but how late) my lack. I see the chasm. And everything you are was making My heart into a bridge by which I might get back From exile, and grow man. And now the bridge is breaking. For this I bless you as the ruin falls. The pains You give me are more precious than all other gains.”
