Kevin DeYoung gives a good, balanced review of this book here.
Here is an excerpt:
Ah yes, another book on the emergent church. I admit I both really wanted to read this book and really didn’t. The wanting is because, as you may know, I too wrote a book on the emerging church. So naturally I was curious what another author–one with blurbs from the likes of Mark Driscoll, Tim Keller, Rob Bell, Scot McKnight, and Tony Jones–had to say about the movement.
But a big part of me didn’t want to read the book. Believe it or not, I don’t live for controversy and I don’t wake up in the morning hoping to jump back into emergenty thoughts. I spent a year of my life researching and writing about the emergent church and then another year teaching and doing interviews about it. That was enough for me. Besides, perhaps I’m naive, but I think most people can now see the emergent movement for what it is. There are enough resources out there now for people to make up their minds and decide whether this is a healthy reform movement or a conversation pushing the boundaries of evangelical faith and sometimes jumping the bounds of orthodoxy itself.
