Quotes from the Book

I am trying here to prevent anyone saying the really foolish thing that people often say about Him: I’m ready to accept Jesus as a great moral teacher, but I don’t accept his claim to be God. That is the one thing we must not say. A man who was merely a man and said the sort of things Jesus said would not be a great moral teacher. He would either be a lunatic — on the level with the man who says he is a poached egg — or else he would be the Devil of Hell. You must make your choice. Either this man was, and is, the Son of God, or else a madman or something worse. You can shut him up for a fool, you can spit at him and kill him as a demon or you can fall at his feet and call him Lord and God, but let us not come with any patronizing nonsense about his being a great human teacher. He has not left that open to us. He did not intend to.
Even in literature and art, no man who bothers about originality will ever be original: whereas if you simply try to tell the truth (without caring twopence how often it has been told before) you will, nine times out of ten, become original without ever having noticed it.
[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.
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.
My argument against God was that the universe seemed so cruel and unjust. But how had I got this idea of just and unjust? A man does not call a line crooked unless he has some idea of a straight line. What was I comparing this universe with when I called it unjust?
And out of that hopeless attempt has come nearly all that we call human history—money, poverty, ambition, war, prostitution, classes, empires, slavery—the long terrible story of man trying to find something other than God which will make him happy.
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.
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.
Nothing you have not given away will ever really be yours.
If I find in myself desires which nothing in this world can satisfy, the only logical explanation is that I was made for another world.
As long as you are proud you cannot know God. A proud man is always looking down on thing and people: and, of course, as long as you are looking down you cannot see something that is above you.
Your real, new self (which is Christ's and also yours, and yours just because it is His) will not come as long as you are looking for it. It will come when you are looking for Him. Does that sound strange? The same principle holds, you know, for more everyday matters. Even in social life, you will never make a good impression on other people until you stop thinking about what sort of impression you are making. Even in literature and art, no man who bothers about originality will ever be original whereas if you simply try to tell the truth (without caring twopence how often it has been told before) you will, nine times out of ten, become original without ever having noticed it. The principle runs through all life from top to bottom, Give up yourself, and you will find your real self. Lose your life and you will save it. Submit to death, death of your ambitions and favourite wishes every day and death of your whole body in the end submit with every fibre of your being, and you will find eternal life. Keep back nothing. Nothing that you have not given away will be really yours. Nothing in you that has not died will ever be raised from the dead. Look for yourself, and you will find in the long run only hatred, loneliness, despair, rage, ruin, and decay. But look for Christ and you will find Him, and with Him everything else thrown in.
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.
If the whole universe has no meaning, we should never have found out that it has no meaning: just as, if there were no light in the universe and therefore no creatures with eyes, we should never know it was dark. Dark would be without meaning.
Progress means getting nearer to the place you want to be. And if you have taken a wrong turning, then to go forward does not get you any nearer. If you are on the wrong road, progress means doing an about-turn and walking back to the right road; and in that case the man who turns back soonest is the most progressive man.
Everyone thinks forgiveness is a lovely idea until he has something to forgive.
Pride gets no pleasure out of having something, only out of having more of it than the next man... It is the comparison that makes you proud: the pleasure of being above the rest. Once the element of competition is gone, pride is gone.
It may be hard for an egg to turn into a bird: it would be a jolly sight harder for a bird to learn to fly while remaining an egg. We are like eggs at present. And you cannot go on indefinitely being just an ordinary, decent egg. We must be hatched or go bad.
Knowledge can last, principles can last, habits can last; but feelings come and go... But, of course, ceasing to be "in love" need not mean ceasing to love. Love in this second sense — love as distinct from "being in love" — is not merely a feeling. It is a deep unity, maintained by the will and deliberately strengthened by habit; reinforced by (in Christian marriage) the grace which both partners ask, and receive, from God... "Being in love" first moved them to promise fidelity: this quieter love enables them to keep the promise. It is on this love that the engine of marriage is run: being in love was the explosion that started it.
I remember Christian teachers telling me long ago that I must hate a bad man's actions but not hate the bad man: or, as they would say, hate the sin but not the sinner. ...I used to think this a silly, straw-splitting distinction: how could you hate what a man did and not hate the man? But years later it occurred to me that there was one man to whom I had been doing this all my life -- namely myself. However much I might dislike my own cowardice or conceit or greed, I went on loving myself. There had never been the slightest difficulty about it. In fact the very reason why I hated the things was that I loved the man. Just because I loved myself, I was sorry to find that I was the sort of man who did those things.
Faith, in the sense in which I am here using the word, is the art of holding on to things your reason has once accepted, in spite of your changing moods.
To what will you look for help if you will not look to that which is stronger than yourself?
Do not waste time bothering whether you ‘love’ your neighbor; act as if you did. As soon as we do this we find one of the great secrets. When you are behaving as if you loved someone, you will presently come to love him.
The Christian says, 'Creatures are not born with desires unless satisfaction for those desires exists. A baby feels hunger: well, there is such a thing as food. A duckling wants to swim: well, there is such a thing as water. Men feel sexual desire: well, there is such a thing as sex. If I find in myself a desire which no experience in this world can satisfy, the most probable explanation is that I was made for another world. If none of my earthly pleasures satisfy it, that does not prove that the universe is a fraud. Probably earthly pleasures were never meant to satisfy it, but only to arouse it, to suggest the real thing. If that is so, I must take care, on the one hand, never to despise, or to be unthankful for, these earthly blessings, and on the other, never to mistake them for the something else of which they are only a kind of copy, or echo, or mirage. I must keep alive in myself the desire for my true country, which I shall not find till after death; I must never let it get snowed under or turned aside; I must make it the main object of life to press on to that country and to help others to do the same.
God is no fonder of intellectual slackers than He is of any other slacker.
Now we cannot...discover our failure to keep God's law except by trying our very hardest (and then failing). Unless we really try, whatever we say there will always be at the back of our minds the idea that if we try harder next time we shall succeed in being completely good. Thus, in one sense, the road back to God is a road of moral effort, of trying harder and harder. But in another sense it is not trying that is ever going tobring us home. All this trying leads up to the vital moment at which you turn to God and say, "You must do this. I can't.
[Repentance] means unlearning all the self-conceit and self -will that we have been training ourselves into... It means killing part of yourself, under-going a kind of death.
The promise, made when I am in love and because I am in love, to be true to the beloved as long as I live, commits me to being true even if I cease to be in love. A promise must be about things that I can do, about actions: no one can promise to go on feeling in a certain way. He might as well promise to never have a headache or always to feel hungry.

About the book

Mere Christianity is a work of Christian apologetics by C.S. Lewis, first published in 1952. It was adapted from a series of talks Lewis delivered on BBC radio between 1941 and 1944, originally issued as three separate volumes: Broadcast Talks (1942), Christian Behaviour (1943), and Beyond Personality (1944). Lewis's aim was to explain and defend the beliefs common to nearly all Christians across denominations, deliberately setting aside the doctrinal disputes that divide particular churches.

The book unfolds in four parts. It opens with an argument from morality, in which Lewis points to a universal 'law of human nature'-a shared sense of right and wrong-as evidence pointing beyond the material world. He then lays out core Christian doctrine, including his well-known 'trilemma' about Jesus (that one must regard him as either liar, lunatic, or Lord), before turning to Christian ethics and the virtues, and finally to the Christian understanding of God and the transformed self.

Written in plain, accessible language for a general audience rather than for scholars, Mere Christianity has become one of the most widely read works of twentieth-century Christian apologetics. It has been credited with influencing many readers' faith and remains a staple of popular theology, valued for its clarity and its focus on the essentials that Lewis believed unite Christians.
