Here's a different approach. What are your big 5 commentaries on the four Gospels and Acts? I want your #1 commentary for each book: Matthew, Mark, Luke, John, Acts. That will be a total of 5 books. If you could only have one on each book, which would it be? What's the first one a seminary student should have on his shelf? Go!
