Why must humanity suffer? In this elegant and thoughtful work, C. S. Lewis questions the pain and suffering that occur everyday and how this contrasts with the notion of a God that is both omnipotent and good. An answer to this critical theological problem is found within these pages. "If God is good and all-powerful, why does he allow his creatures to suffer pain?" And what about the suffering of animals, who neither deserve pain nor can be improved by it? The greatest Christian thinker of our time sets out to disentangle these knotty issues. With his signature wealth of compassion and insight, C. S. Lewis offers answers to these crucial questions and shares his hope and wisdom to help heal a world hungering for a true understanding of human nature. - Cover.
"We can ignore even pleasure. But pain insists upon being attended to. 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."
Of course, there's hundreds of more writings on this, but Lewis is always an easy place to start.
I also recommend his book The Problem of Pain, which talks about man's long history of belief in the supernatural, despite the outlandishness of the idea.
C. S. Lewis was an atheist until his early 30s. He taught at Oxford and then Cambridge, during the first half of the 20th century.
