At the time, I liked the Revelation Climax book. Because when It came out, I placed a ton of them in field service. I had just started pioneering and thought I was informing the whole community about what was approaching within the next ten years or so.......I have since re-read it and found so many holes and absurdity in it, that I'm embarassed I bothered placing it with all of those nice people.
I do agree, the Greatest Man book is very good and fairly accurate and balanced. I remember studying the Commentary on the Letter of James when I was young, but I was too young to really remember what it said.
