This book (2006) is a big improvement on Ray Comfort's Hell's Best Kept Secret (1989). I will say at the start that this book, and I suppose his training program (on DVDs) would make a person into a witness for Christ. I do thank the Lord for that, as Paul was grateful for anyone who preached the Gospel, even insincerely (see Phil. 1:12-18; not that Comfort is insincere). Having said that, the previous book has made me wary of Comfort. Here are some of the problems with that first book, which I reviewed here on the BB: obsessing on the Law without defining it (the Decalogue? the OT? What?), his Charismatic beliefs (he recommended tongues), his poor hermeneutics (allegorical interpretation), his failure to define and emphasize the Gospel (for him the Law always comes first), and so forth. These are the things I'll be looking for in this book.
