A few cautions. First, this is not a scholarly work; it is written for laypeople. This is a pastoral work. If you're looking for something very meaty, this won't be it. But you will walk away with a cursory understanding of various perspectives.
Second, if you're looking for someone to tell you the "right" theory, you'll be disappointed. While I could guess at Rinne's personal views, he only tips his and one topic, and he expressly states it's the view he personally subscribes to at the moment.
Third, if you're passionate about your theories, Rinne will not call you out as wrong or validate your views. He is really just trying to highlight the various views and bring understanding to all, regardless of their views.
This quick read is worthy of your attention. If your small group is looking for a resource to spur discussion, this (along with the other Questions Christians Ask works) would be a great place to start.
Note: I received a review copy of the book from the publisher. I was required to provide an honest, not necessarily favorable, review, and the opinions expressed are mine.
