One of my very favorite living pastor-theologians is D.A. Carson. He is an unusual combination of a world-class biblical scholar,a very wise and insightful apostolic-type leader who approaches things with a pastor's perspective and heart. I have benefited tremendously from his books, sermons and his devotional, "For the Love of God".
I highly recommend listening to some of the 200 or so of his sermons on the Gospel Coalition site. Check out the D.A, Carson sermon archive here and enjoy!
