Investigating the meanings and uses of "spiritus" in a variety of early modern disciplines and fields - natural philosophy, theology, music, literature and the visual arts - this book revisits the ambivalent history of a central ancient concept in a period of crisis and change.

The truth about demons is far stranger—and even more fascinating—than what's commonly believed. Are demons real? Are they red creatures with goatees holding pitchforks and sitting on people's shoulders while whispering bad things? Did a third of the angels really rebel with Satan? Are demons and "principalities and powers" just terms for the same entities, or are they different members of the kingdom of darkness? Is the world a chaotic mess because of what happened in Eden, or is there more to the story of evil? What people believed about evil spiritual forces in ancient biblical times is often very different than what people have been led to believe about them today. And this ancient worldview is missing from most attempts to treat the topic. In Demons, Michael Heiser debunks popular presuppositions about the very real powers of darkness. Rather than traditions, stories, speculations, or myths, Demons is grounded in what ancient people of both the Old and New Testament eras believed about evil spiritual forces and in what the Bible actually says. You'll come away with a sound, biblical understanding of demons, supernatural rebellion, evil spirits, and spiritual warfare.

In The Unseen Realm, Dr. Michael Heiser examines the ancient context of Scripture, explaining how its supernatural worldview can help us grow in our understanding of God. He illuminates intriguing and amazing passages of the Bible that have been hiding in plain sight. You'll find yourself engaged in an enthusiastic pursuit of the truth, resulting in a new appreciation for God's Word. Why wasn't Eve surprised when the serpent spoke to her? How did descendants of the Nephilim survive the flood? Why did Jacob fuse Yahweh and his Angel together in his prayer? Who are the assembly of divine beings that God presides over? In what way do those beings participate in God's decisions? Why do Peter and Jude promote belief in imprisoned spirits? Why does Paul describe evil spirits in terms of geographical rulership? Who are the "glorious ones" that even angels dare not rebuke? After reading this book, you may never read your Bible the same way again. Endorsements "There is a world referred to in the Scripture that is quite unseen, but also quite present and active. Michael Heiser's The Unseen Realm seeks to unmask this world. Heiser shows how important it is to understand this world and appreciate how its contribution helps to make sense of Scripture. The book is clear and well done, treating many ideas and themes that often go unseen themselves. With this book, such themes will no longer be neglected, so read it and discover a new realm for reflection about what Scripture teaches." --Darrell L. Bock, Executive Director for Cultural Engagement, Senior Research Professor of New Testament Studies, Howard G. Hendricks Center for Christian Leadership and Cultural Engagement "'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. No one is going to agree with everything in his book, but the subject deserves careful study, and so does this book." --John Goldingay, David Allan Hubbard Professor of Old Testament, School of Theology, Fuller Theological Seminary "This is a 'big' book in the best sense of the term. It is big in its scope and in its depth of analysis. Michael Heiser is a scholar who knows Scripture intimately in its ancient cultural context. All--scholars, clergy, and laypeople--who read this profound and accessible book will grow in their understanding of both the Old and New Testaments, particularly as their eyes are opened to the Bible's 'unseen world.'" --Tremper Longman III, Robert H. Gundry Professor of Biblical Studies, Westmont College
