This course provides a broad overview of the supernatural worldview of the biblical writers across the Old and New Testaments. Elements of this course include: (1) what the writers thought about the reality of spiritual entities loyal to, and in rebellion against, the God of Israel; (2) how the intersection (positive and negative) of spirit beings in the human realm propels the meta-narrative of biblical theology; and (3) how the engagement of the spiritual and human realm impacts other areas of biblical theology. The purpose of this course is to demonstrate the necessity and reward of interpreting biblical content in light of the writers’ ancient cultural, religious, and intellectual frame of reference.
