Frederick Fyvie Bruce FBA was a Biblical scholar who supported the historical reliability of the New Testament. His first book, The New Testament Documents: Are They Reliable? (1943), was voted by the American evangelical periodical Christianity Today in 2006 as one of the top 50 books "which had shaped evangelicals".
An older book I read several years ago and found it to be excellent reading for those who want to grow young converts. He deals with passages in 1 Thess to explain and discuss Paul's method in Thessalonica. Good book, short read.
