First, I will admit that I did not read the entire book. But, still, when the author is saying that his opinion is fact, that can't be a good start. If it would have been more historical, I could have enjoyed it better. But I don't need to read about this guy's religious views to remind me that I can be an instrument in God's hands.
There wasn't even a chapter on Ruth! Furthermore, in the first chapter on Eve, he basically pounds it into the reader's head that Eve was a big sinner and she messed up life for the rest of us. That's definitely not something I agree with.
