In Angels and Demons, Michael Heiser debunks popular presuppositions about God’s supernatural servants and the very real powers of darkness. Rather than traditions, stories, speculations, or myths, these books are grounded in what ancient people of both the Old and New Testament eras believed about spiritual forces and in what the Bible actually says.
What people believed about good and evil spiritual forces in ancient biblical times is 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.
