“The more you obey your conscience, the more your conscience will demand of you.”
Book IV, Chapter 8, "Is Christianity Hard or Easy?"
Mere Christianity (1952)
Mere Christianity is a theological book by C. S. Lewis, adapted from a series of BBC radio talks made between 1941 and 1944, while Lewis was at Oxford during the Second World War. Considered a classic of Christian apologetics, the transcripts of the broadcasts originally appeared in print as three separate pamphlets: The Case for Christianity , Christian Behaviour , and Beyond Personality . Lewis was invited to give the talks by James Welch, the BBC Director of Religious Broadcasting, who had read his 1940 book, The Problem of Pain.

Book II, Chapter 3, "The Shocking Alternative"
Mere Christianity (1952)
Context: 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 be either a lunatic—on a 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 patronising nonsense about His being a great human teacher. He has not left that open to us. He did not intend to.
Book III, Chapter 12, "Faith"
Mere Christianity (1952)
Context: There are two parodies of the truth which different sets of Christians have, in the past, been accused by other Christians of believing: perhaps they may make the truth clearer. One set were accused of saying, "Good actions are all that matters. The best good action is charity. The best kind of charity is giving money. The best thing to give money to is the Church. So hand us over ₤10,000 and we will see you through." The answer to that nonsense, of course, would be that good actions done for that motive, done with the idea that Heaven can be bought, would not be good actions at all, but only commercial speculations. The other set were accused of saying, "Faith is all that matters. Consequently, if you have faith, it doesn't matter what you do. Sin away, my lad, and have a good time and Christ will see that it makes no difference in the end." The answers to that nonsense is that, if what you call your "faith" in Christ does not involve taking the slightest notice of what he says, then it is not Faith at all—not faith or trust in Him, but only intellectual acceptance of some theory of Him.
Book III, Chapter 10, "Hope"
Mere Christianity (1952)
Context: If you read history you will find that the Christians who did most for the present world were just those who thought most of the next... It is since Christians have largely ceased to think of the other world that they have become so ineffective in this. Aim at Heaven and you will get earth "thrown in": aim at earth and you will get neither.
Book II, Chapter 4, "The Perfect Penitent"
Mere Christianity (1952)
Context: He [God] lends us a little of His reasoning powers and that is how we think: He puts a little of His love into us and that is how we love one another. When you teach a child writing, you hold its hand while it forms the letters: that is, it forms the letters because you are forming them. We love and reason because God loves and reasons and holds our hand while we do it.
“Now, to-day, this moment, is our chance to choose the right side.”
Book II, Chapter 5, "The Practical Conclusion"
Mere Christianity (1952)
Context: Now, to-day, this moment, is our chance to choose the right side. God is holding back to give us that chance. It will not last for ever. We must take it or leave it.
Book II, Chapter 4, "The Perfect Penitent"
Mere Christianity (1952)
Context: We are told that Christ was killed for us, that His death has washed out our sins, and that by dying He has disabled death itself. That is the formula. That is Christianity. That is what has to be believed. Any theories we build up as to how Christ's death did all this are, in my view, quite secondary: mere plans or diagrams to be left alone if they do not help us, and, if they do help us, not to be confused with the thing itself.
Book II, Chapter 3, "The Shocking Alternative"
Mere Christianity (1952)
Context: Among these Jews there suddenly turns up a man who goes about talking as if He was God. He claims to forgive sins. He says He has always existed. He says He is coming to judge the world at the end of time. Now let us get this clear. Among Pantheists, like the Indians, anyone might say that he was a part of God, or one with God: there would be nothing very odd about it. But this man, since He was a Jew, could not mean that kind of God. God, in their language, meant the Being outside of the world, who had made it and was infinitely different from anything else. And when you have grasped that, you will see that what this man said was, quite simply, the most shocking thing that has ever been uttered by human lips.
Book I, Chapter 5, "We Have Cause to Be Uneasy"
Mere Christianity (1952)
Context: We have two bits of evidence about the Somebody. One is the universe He has made. If we used that as our only clue, I think we should have to conclude that He was a great artist (for the universe is a very beautiful place), but also that He is quite merciless and no friend to man (for the universe is a very dangerous and terrifying place.)... The other bit of evidence is that Moral Law which He has put in our minds. And this is a better bit of evidence than the other, because it is inside information. You find out more about God from the Moral Law than from the universe in general just as you find out more about a man by listening to his conversation than by looking at a house he has built.
“Goodness is either the great safety or the great danger—according to the way you react to it.”
Book I, Chapter 5, "We Have Cause to Be Uneasy"
Mere Christianity (1952)
Context: 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.
Book II, Chapter 1, "The Rival Conceptions of God"
Mere Christianity (1952)
Context: 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?
Book III, Chapter 6, "Christian Marriage"
Mere Christianity (1952)
Context: Being in love is a good thing, but it is not the best thing. There are many things below it, but there are also things above it. You cannot make it the basis of a whole life. It is a noble feeling, but it is still a feeling... 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 marriages) 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.

Book IV, Chapter 4, "Good Infection"
Mere Christianity (1952)
Context: They [Christians] believe that the living, dynamic activity of love has been going on in God forever and has created everything else. And that, by the way, is perhaps the most important difference between Christianity and all other religions: that in Christianity God is not an impersonal thing nor a static thing—not even just one person—but a dynamic pulsating activity, a life, a kind of drama, almost, if you will not think me irreverent, a kind of dance … (The) pattern of this three-personal life is … the great fountain of energy and beauty spurting up at the very center of reality.
