Greg's book should be here really soon and it looks well worth grabbing a copy. Pastors: This would be really useful to put in the hands of your church members.
A couple of questions for Greg:
1. Why did you write the book?
2. Can you summarize (briefly) what are the major challenges to the gospel today?
3. Who should read the book?
4. You wrote a chapter on the Cross being at the center....why? Isn't that obvious to most Christians?
