Who were the "sons of God"? Who were the Nephilim? Where do angels fit into the supernatural hierarchy? Why did God find it necessary to have the Israelites destroy the populations of entire cities-man, woman, and child? What relation does Jesus bear to the rest of the supernatural world? Dr. Michael S. Heiser tackles these questions and many more in his books Supernatural and The Unseen Realm.

If you’ve ever wondered why the Bible mentions giants, divine councils, and spiritual warfare but your Sunday school lessons glossed over them, Dr. Michael S. Heiser’s work will change how you read Scripture forever. These two companion books—Supernatural and The Unseen Realm—present fifteen years of scholarly research into what the Bible actually says about the supernatural world, stripped of theological sanitizing and tradition-based explanations.

Dr. Heiser, a Scholar-in-Residence at Faithlife Corporation, tackles the passages most Bible studies skip: Who were the Nephilim? What did ancient Israelites understand about the “sons of God”? Why did God command the destruction of entire Canaanite cities? How does Jesus fit into the supernatural hierarchy? Instead of explaining away these difficult texts, Heiser illuminates them using the same ancient Near Eastern context the original writers and readers would have understood. You’ll discover a coherent biblical worldview of the unseen realm that’s been hiding in plain sight all along.

Who Is This For?

Supernatural is written for everyday readers who want accessible insights without academic jargon—perfect for personal study or small groups. The Unseen Realm dives deeper with extensive documentation and complex analysis, making it ideal for pastors, seminary students, and serious Bible scholars who want the full academic treatment. Both books cover the same revolutionary material at different depths, so you can choose based on your background and goals.

Bottom Line

These books don’t add anything to Scripture—they remove the filters that have kept you from seeing what’s already there. If you’re ready to understand the Bible’s supernatural worldview as ancient readers did, and you’re not afraid of having your theological assumptions challenged, this is essential reading. Fair warning: you won’t read Genesis, Psalms, or the Gospels the same way again.

  • Dr. Michael S. Heiser, a Scholar-in-Residence at Faithlife Corporation, presents fifteen years of research on what the Bible really says about the unseen world of the supernatural-unfiltered by tradition or by theological presuppositions. “People shouldn’t be protected from the Bible,” Dr. Michael S. Heiser says, but theological systems often do just that, by “explaining away” difficult or troublesome passages of Scripture because their literal meaning doesn’t fit into our tidy systems.
  • Who were the “sons of God”? Who were the Nephilim? Where do angels fit into the supernatural hierarchy? Why did God find it necessary to have the Israelites destroy the populations of entire cities-man, woman, and child? What relation does Jesus bear to the rest of the supernatural world? Dr. Michael S. Heiser tackles these questions and many more in his books Supernatural and The Unseen Realm.
  • In both books, Dr. Michael S. Heiser shines a light on the supernatural world-not a new light, but rather the same light the original, ancient readers-and writers-of Scripture would have seen it in.
  • After reading these books, you won’t be able to read the Bible in the same way again.
  • Supernatural, What the Bible Teaches about the Unseen World-and Why it Matters presents this approach to reading and understanding scripture for the person in the pew. The Unseen Realm covers the same material but at a deeper, complex, and highly documented way, for pastors, the seminarian, or serious students of the Bible.
