In this provocative book, Lewis describes our lives like a photo negative, turning our whites to blacks, and our blacks to whites. A senior devil gives advice to a junior devil, and in so doing gives us a different slant on our everyday sins. A must read, but we recommend it for older students and adults.
Something that Lewis brings out in a subtle undertone in this book is that demons can't understand God's pure, unselfish love for us humans. They are mystified about what He could possibly gain for Himself for all his trouble with us pathetic mortals...
"The truth is, I slipped by mere carelessness into saying that the Enemy really loves the humans. That, of course, is an impossibility. He is one being, they are distinct from Him. Their good cannot be His. All His talk about Love must be a disguise for something else—He must have some real motive for creating them and taking so much trouble about them."
