“Anyone who says he knows God's intention is showing a lot of very human ego.”

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.
