The Problem of Pain, by C.S. Lewis

This book is a thorough discussion of why pain exists in a world created by a benevolent God. I always enjoy reading C.S. Lewis's books because of his clear presentation of complex ideas and straightforward readable writing style. This book was no exception. It is an intellectual approach to the subject, so it would be a great choice for someone mulling dispassionately over the problem of reconciling the existence of pain with that of God, but perhaps not so much for someone who is looking for consolation because they are actually going through hard times.
