My entire life, countless people have walked up to me and passed out Jesus literature, and then walked away, thinking they had done something good (rather, made themselves feel good). I currently live in the buckle of the bible belt, and experience hit-and-runs of this type all of the time. While, this example is simplistic, it is to make a point...
Most of the Christians I've encountered in my life time have intelligence and common sense, yet they continue to miss the boat when it comes to evangelism. While their intentions may be good...the road to hell is paved with good intentions.
Simpson's wisdom and intelligence leap out from every page of this well-written book. It is a must read for mature and new Christians alike, and I look forward to his next book!
