Dr. Akin is the president of Southeastern, the seminary I am attending. He has been preaching through the book of Titus during chapel, and I must say he is as fine a Bible expositor as I have ever heard. Based on his messages, I decided to pick up a copy of a commentary he wrote on the books of 1st, 2nd, and 3rd John (it's part of the New American Commentary (NAC) series). The campus bookstore had it on sale for $20, which is a good deal. Maybe I'll get a chance to study through it this summer.
