OT Biblical Theology
From the evangelical preacher's point of view, biblical theology involves the quest for the big picture, or the overview of biblical revelation. It is of the nature of biblical theology that it tells a story rather than sets out timeless principles in abstraction. It does contain many timeless principles, but not in abstract. They are given in an historical context of progressive revelation. If we allow the Bible to tell its own story, we find a coherent and meaningful whole.
