WATCH: Demons: Why the Bible’s Darkest Battles Were Never Fully Told — Part 1 | Michael Heiser

Spiritual warfare in the Old Testament has deeper roots than often acknowledged, extending beyond New Testament concepts. Key Old Testament passages include Genesis 3, where the serpent is a supernatural rebel opposing God’s will, Isaiah 14 and Ezekiel 28, which depict the fall of rebellious divine beings, and Genesis 6, which describes “the sons of God” (likely fallen angels) interbreeding with human women, spreading forbidden knowledge that escalates human depravity.

Daniel 10 reveals ongoing cosmic battles between divine princes representing nations, with Michael as Israel’s protector opposing other supernatural rulers. Deuteronomy 32:8-9 and Psalm 82 further depict a “cosmic geography,” where nations are governed by spiritual beings under divine judgment.

The Old Testament also shows how idolatry is linked to these fallen beings, who hold power behind pagan gods, and how land and divine presence are connected, as seen in stories like Naaman’s recognition of Yahweh through Israel’s land. Israel was meant as a holy example to the nations, but it failed, leaving a world fragmented and under the rule of lesser gods until the Messiah arrives to restore all things, addressing the multiple layers of rebellion and spiritual conflict introduced in the Old Testament.
