“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.” 

“We never find out the strength of the evil impulse inside us until we try to fight it: and Christ, because he was the only man who never yielded to temptation, is also the only man who knows to the full what temptation means.”

“Give me all of you!!! I don’t want so much of your time, so much of your talents and money, and so much of your work. I want YOU!!! ALL OF YOU!! I have not come to torment or frustrate the natural man or woman, but to KILL IT! No half measures will do. I don’t want to only prune a branch here and a branch there; rather I want the whole tree out! Hand it over to me, the whole outfit, all of your desires, all of your wants and wishes and dreams. Turn them ALL over to me, give yourself to me and I will make of you a new self---in my image. Give me yourself and in exchange I will give you Myself. My will, shall become your will. My heart, shall become your heart.”

“All that is not eternal is eternally out of date.”

“One of the most cowardly things ordinary people do is to shut their eyes to facts.”

“Reason is the natural order of truth; but imagination is the organ of meaning.”

“I have said that she had no face; but that meant she had a thousand faces”

“I could never have gone far in any science because on the path of every science the lion Mathematics lies in wait for you.”

“I believe that many who find that "nothing happens" when they sit down, or kneel down, to a book of devotion, would find that the heart sings unbidden while they are working their way through a tough bit of theology with a pipe in their teeth and a pencil in their hand.”

“Above all, do not attempt to use science (I mean, the real sciences) as a defence against Christianity. They will positively encourage him to think about realities he can’t touch and see. ”

“The quest of the Inner Ring will break your hearts unless you break it. But if you break it, a surprising result will follow. If in your working hours you make the work your end, you will presently find yourself all unawares inside the only circle in your profession that really matters. You will be one of the sound craftsmen, and other sound craftsmen will know it. This group of craftsmen will by no means coincide with the Inner Ring or the Important People or the People in the Know. It will not shape that professional policy or work up that professional influence which fights for the profession as a whole against the public: nor will it lead to those periodic scandals and crises which the Inner Ring produces. But it will do those things which that profession exists to do and will in the long run be responsible for all the respect which that profession in fact enjoys and which the speeches and advertisements cannot maintain. And if in your spare time you consort simply with the people you like, you will again find that you have come unawares to a real inside: that you are indeed snug and safe at the center of something which, seen from without, would look exactly like an Inner Ring. But the difference is that its secrecy is accidental, and its exclusiveness a by-product, and no one was led thither by the lure of the esoteric: for it is only four or five people who like one another meeting to do things that they like. This is friendship. Aristotle placed it among the virtues. It causes perhaps half of all the happiness in the world, and no Inner Ring can ever have it.”

“Nothing you have not given away will ever really be yours.”

“All that we call human history--money, poverty, ambition, war, prostitution, classes, empires, slavery--[is] the long terrible story of man trying to find something other than God which will make him happy.”

“If they are wrong they need your prayers all the more; and if they are your enemies, then you are under orders to pray for them. That is one of the rules common to the whole house.” 

“You thought you were going to be made into a decent little cottage: but He is building a palace. He intends to come and live in it himself. (Quoted by C.S.Lewis in Mere Christianity)”
