My church book group read this, and it definitely helped to be able to discuss it as we went along. C.S. Lewis built a firm foundation for all his arguments and painted some great word pictures as analogy for spiritual concepts.....but he took far too many words to get there. Obviously, a writer of his caliber doesn't need my input, but several chapters seemed unnecessarily drawn out--probably to fit their original radio talk format. Like eating your vegetables as a kid, reading this may not have been my first choice, but I have to admit it was probably good for me.
