Darrell Bock, the professor of New Testament at Dallas Theological Seminary, is now blogging over at bible.org (a most edifying site that I frequent often).
He has written many commentaries and books that grace my shelves in my office. He also wrote the best book on "The Da Vinci Code," in my opinion. His massive two-volume commentary on Luke from the Baker Exegetical Commentary line is superb.
Visit him often. You'll be better for it.
