The Problem of Pain – C.S. Lewis.

C. S. Lewis was a man of great insight and understanding. He was one of those rare men who can make great mysteries intelligable. Here's one of my favourite quotes:

"God whispers to us in our pleasures, speaks in our conscience, but shouts in our pains: it is His megaphone to rouse a deaf world."

(C.S. Lewis, The Problem of Pain, Centenary Press, 1940, 81.)
