This book was thought provoking in many ways. The way the Lewis weaved much of the imagery of scripture throughout and how he treats sci-fi like a stepping stone to what God could be doing in Revelation is brilliant. Sometimes I wonder if it borders on heresy, but for the most part I think he keeps it pretty tame and it's easy to envision a heaven like this that God (Maleldil) is divinely and justly orchestrating. It's a bit heady in the last chapter, but overall I really enjoyed the book.
