I can't seem to find my copy of the book right now, having recently moved, it's somewhere among the books in my shelves, but... can't find it. The sentence in question is near the end of one of the chapters in the first half of the book. The second half of the book seems to assume the first half of the book is a given and is consequently a complete waste of time, being built upon a false premise.

The only people who think this is a reasonable book are people who are already Christians.
