Book Review: "The Unseen Realm" by Michael S. Heiser

Summary of "The Unseen Realm: Recovering the Supernatural" by Michael S. Heiser

What if the Bible isn’t just a book about God and humans, but also about an entire unseen world teeming with divine beings, cosmic battles, and a hierarchy of supernatural forces? In The Unseen Realm, biblical scholar Michael S. Heiser invites readers to look beyond the conventional, domesticated view of scripture and step into a supernatural paradigm—one that, he argues, was completely natural to the original authors and readers of the Bible.

At the heart of Heiser’s argument is the concept of the divine council, a heavenly assembly of gods (elohim) under the authority of Yahweh. He traces this concept throughout the Old Testament, particularly in passages like Psalm 82, where God presides over other divine beings, rebuking them for their injustice. This idea challenges traditional monotheistic interpretations, but Heiser clarifies that while many elohim exist, only one—Yahweh—is supreme, eternal, and uncreated.

From Eden to Babel, Heiser reinterprets familiar stories through this supernatural lens. The serpent in Genesis 3? Not just a talking snake, but a divine rebel seeking to undermine God’s rule. The Tower of Babel? Not just a failed architectural project, but a cosmic rebellion that led God to disinherit the nations, handing them over to lesser gods while reserving Israel for Himself. This moment, according to Heiser, sets up a spiritual conflict that runs through the entire biblical narrative.

Heiser also reexamines key biblical figures. Abraham’s calling, for instance, isn’t just a random divine selection but a strategic move to reclaim the nations. Moses’ confrontations with Pharaoh aren’t just about political liberation but spiritual warfare against Egypt’s gods. Even Israel’s conquest of Canaan takes on new meaning: the targeted destruction of Nephilim-descended tribes—hybrid offspring of divine beings and humans from Genesis 6, who were part of an ancient supernatural rebellion.

When we arrive at the New Testament, Jesus emerges as the ultimate agent of cosmic restoration. His ministry isn’t just about moral teaching or personal salvation—it’s a direct challenge to the powers of darkness. The demons He exorcises? Representatives of the fallen divine beings from Babel. His crucifixion? A deception against these powers, leading them to orchestrate their own downfall. His resurrection? The ultimate victory that reclaims authority over the nations.

Heiser’s work is deeply rooted in ancient Near Eastern culture, linguistic analysis, and Second Temple Jewish literature. He argues that modern Christianity has largely stripped the Bible of its supernatural worldview, replacing it with a sterile, rationalistic interpretation. By recovering this lost perspective, he claims, we can better understand the Bible as its original audience did.

Throughout The Unseen Realm, Heiser presents an exhilarating, sometimes unsettling vision of scripture—one where spiritual beings are active players in God’s plan, where cosmic conflicts shape human history, and where the Bible’s supernatural elements are meant to be taken seriously. Whether one agrees with every point or not, the book challenges readers to rethink what they thought they knew about the unseen world of the Bible.
