This book is a summary of Jerram Barrs' approach to evangelism and outreach--largely a summary of one of the best classes I had in seminary. A great approach to reaching out with the grace of God to the unbelieving.
Jerram taught this material to us in several classes at Covenant Theological Seminary in the early 1990s.
However, that material only occupies a small section towards the end. It is very valuable.
Unfortunately, the bulk of the volume seems given to polemics against other Evangelicals. I think the author would have "caught more flies with honey than with vinegar" if he'd followed his own advice in writing this volume. I fear that it will turn off a large percentage of the very people that need to read that important end section.
