JBC sees the same God in the OT and the NT, and that comes clear in his commentaries. His prose makes books I didnt really enjoy before come alive- and while I disagree with some of his conclusions (ie, God doesnt like music in worship services, as he points out in the Pslams, but has a time with in the David history books (the Samuels)). His commentary on Job is excellent, because where hes NOT sure, he gives a few interpretations and leaves it to the reader to decide.But what I like most is how he blends our NT God into the OT seamlessly.
(Wish he werent so tough on the Catholics, but whatevs.)
