I had an email conversation with Greg a year ago about The Shack, Paul Young, Jacques Ellul, and Theodicy. He seemed very intrigued with the book but by his review it seems that he has just recently got around to reading it.

I encourage anyone that hasn't read it to read it. I am just so thrilled by the conversation that is happening around the message in this book and it's good to now have Greg a part of that conversation.
