C.S. Lewis' Masterpiece - Mere Christianity
Book 2 Chapter 1 Excerpt
For Christianity is a fighting religion. It thinks God made the world-that space and time, heat and cold, and all the colours and tastes, and all the animals and vegetables, are things that God "made up out of His head" as a man makes up a story. But it also thinks that a great many things have gone wrong with the world that God made and that God insists, and insists very loudly, on our putting them right again.

And, of course, that raises a very big question. If a good God made the world why has it gone wrong? And for many years I simply refused to listen to the Christian answers to this question, because I kept on feeling "whatever you say, and however clever your arguments are, isn't it much simpler and easier to say that the world was not made by any intelligent power? Aren't all your arguments simply a complicated attempt to avoid the obvious?" But then that threw me back into another difficulty.

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? If the whole show was bad and senseless from A to Z, so to speak, why did I, who was supposed to be part of the show, find myself in such violent reaction against it? A man feels wet when he falls into water, because man is not a water animal: a fish would not feel wet.
