I once heard it recommended that, because there are so many books to read, you only give a book 50 pages to get your attention. If it fails to do so by then, move on. (It was even suggested that if you're over 50, subtract your age from 100, and that's how many pages you should give it. For example, if you are 75, only give a book 25 pages to get your attention.)
With that said, I gave this book 100 pages, and it didn't quite cut it. Mainly, I feel that after reading Josh McDowell's Last Christian Generation this book has nothing new to add to the conversation. While McDowell's work at least proposed a new(ish) solution – process – this work seems to have nothing novel to propose. Love the sinner not the sin; truth is absolute; the battles of the 60s aren't over; etc.
Really, it's not a bad book if you haven't read anything on the issue. I just didn't get anything new from encountering it.
