Michael Heiser has done a great service to all who want to understand the biblical theology of demons, the supernatural powers in rebellion against God. He gives a detailed exploration of the biblical materials as well as the best of the literature of ancient Jewish writers. He correctly believes that we must read the biblical accounts in the context of their ancient worldview. Reviewing all this material, helpfully gathered into this book, will challenge most everyone's understanding of demons. His work is controversial so he brings the work of those who differ with him into his discussions. The study will correct widely-held errors in modern demonology and make us more faithful followers of the One who has won the decisive victory over the Devil. -Gerry Breshears, Professor of Theology, Western Seminary, Portland

This book brings clarity and coherence to what the Bible is and is not trying to tell us about the nature and origins of spiritual evil. Reading Heiser's work has a way of exposing just how much we have unconsciously rewritten the Bible to fit our modern sensibilities, and how we've muddled the Biblical storyline by underestimating the themes explored in this book. Get ready for many lightbulb moments, and for a whole new appreciation of biblical texts you thought you already understood. This book is highly recommended! -- Tim Mackie, co-creator of The Bible Project
