When I was in graduate school at BJU, among my favorite classes was Systematic Theology by Robert Bell.
Dr. Bell was an excellent teacher and I enjoyed his class tremendously. He did a great job of bringing the subject to life and for such an important subject, that is vital. I remember him talking about theology being the queen of the sciences and the idea that sciences usually had labs and suggesting that we eat a bunch of lemons to see what it means to have our "teeth set on edge" (see Jer. 31:29-30).
In addition to Systematic Theology, one of the other classes that Dr. Bell taught was Advanced OT Theology.
BJU Press has recently released a new book by Dr. Bell on this subject entitled, "Theological Messages of the Old Testament Books". The book's list price - and Amazon's price is $39.95. It is currently ON SALE at the BJU Campus Store for $23.97. (It is about a 500 page book according to Andy Naselli, which is where I heard about its release - thanks Andy.)
From the blub at Amazon.com, we read the following:
In The Theological Messages of the Old Testament Books, Robert D. Bell suggests strategies for understanding and preaching every book of the Old Testament. Following the method for biblical theology outlined in his introduction, Bell bases each study firmly on the actual text rather than on imposed theological categories. Students will find the tools they need to understand the text of each Old Testament book on its own terms. Pastors will find resources for preaching sermons or series on a book's themes, characters, or overall message. Sample sermons and scores of tables included.
While you are at the BJU Campus bookstore, you can also find some currently good deals on a couple of other books worth picking up if you do not already own them.
Dr. Michael P. V. Barrett's book Complete in Him: A Guide to Understanding and Enjoying the Gospel (recently back in print) is also available for $11.89, Robert Vincent's Gospel Primer is available for $7.67 and Colin Marshall and Tony Payne's book that has gotten considerable attention lately, The Trellis and the Vine is available for $10.49. (I have read some good reviews of some of these and I am looking forward to reading them.)
