This is a neat little book, coming in at right at 100 pages. In each chapter, Bruce highlights one of Paul's friends, co-workers, or hosts: Ananias of Damascus, Barnabas, Silas, Timothy, Luke, Priscilla & Aquilla, Apollos, Titus, Onesimus, Mark, and two chapters on names where less information is known. It was originally written as a series of articles in The Harvester. Not overly academic, this slim volume is very accessible to the lay-person, tying together threads from Acts and Paul's letters, it gives a clearer understanding of who some of these people where than may otherwise gleaned from a casual reading of the New Testament.
I greatly enjoy Bruce's writing style and the fact that he is a conservative scholar. The only reason I give it three stars is that I usually reserve higher praise for more in-depth works. In the future I look forward to reading more of Bruce's writings.
