This was a helpful summary of the New Testament's reliability. It is historically consistent with outside documents (Josephus tells the same story we find in Acts 12:20-23, for instance). Even where other writings are hostile or indifferent to Christianity, they do not refute the NT's claims. Bruce examines why some books weren't included in Scripture and others were disputed. He considers the Gospel differences helpfully, and Paul and Luke's Acts, also. He shows there are far more NT texts closer to the original writing than we have for most other major works (Caesar, Socrates, etc.), the historicity of which we do not question.
All this in 120 pages! Highly recommended, especially for seminary students and any Christian who is struggling with doubts about the faith once delivered to the saints.
