New Testament Biblical Theology lecture series on iTunes, which seems to be the lecture series upon which his New Testament Biblical Theology: The Unfolding of the Old Testament In the New was based.

It’s a strongly exegetical treatment, and he emphasizes the “inaugurated” components of the Old Testament’s “last days” all throughout the New Testament. Beale stresses that Christ has a “back story” that extends all through the entire sweep of the Old Testament back to Adam, what he calls “the Old Testament background”.
