New edition of a bestseller (over 175k copies sold) that features more content from Michael S. Heiser

If it’s weird, it’s important.

To celebrate its tenth anniversary, The Unseen Realm Expanded Edition features a deluxe hardcover format and new content from Heiser never before available in print, further unveiling the unseen realm.

Talking snakes. Giants. A heavenly council. Imprisoned spirits. Your Bible is filled with strange things, but what do they mean and why do they matter? In The Unseen Realm, Michael Heiser unveils the supernatural worldview of the Bible. Heiser shows how understanding the Bible’s ancient context reveals surprises hiding in plain sight. By reading the Bible with the mindset of an ancient Israelite, you will learn new things about God, yourself, and the world. You may never read your Bible the same way again.

“How was it possible that I had never seen that before? Dr. Heiser’s survey of the complex reality of the supernatural world as the Scriptures portray it covers a subject that is strangely sidestepped.”

―John Goldingay, David Allan Hubbard Professor of Old Testament, School of Theology,  Fuller Theological Seminary 

“There is a world referred to in the Scripture that is quite unseen, but also quite present and active. The Unseen Realm seeks to unmask this world.”

―Darrell L. Bock, Executive Director of Cultural Engagement and Senior Research Professor of New Testament Studies, Dallas Theological Seminary
