This is one of the best at getting into the mind of the radically unchurched.
On the downside, this book (like most on the subject) takes a narrative approach to each chapter. Some chapters have useful take-away summaries. What I would have liked but did not find in the chapters were:
1. Discussion or review questions at the end of each chapter
2. Application exercise(s) at the end of each chapter
So, in my view, this book fell short on providing clear, easy to adopt "how to" ways to build effective relationship evangelism habits.
A promising new book that I may use is Evangelism Outside The Box (Rick Richardson, 2000).
Older books that have worked well for me in teaching others are: (roughly in order of preference): Power Evangelism (John Wimber, 1992), Witnessing Without Fear (Bill Bright, 1987), Out of the Salt Shaker (Rebecca Pippert).
