It has a very Libertarian view of God; basically, it asked the question “are we really ‘free’ if we don’t AT LEAST have three options to choose from? A ‘For’ or ‘ against’ simple binary choice are not enough, ‘neutral’ should also be an option”, seems to be the underlying moral of the story, in my estimation.

I wonder what Chesterton, for whom the book is dedicated, would have made of that.
