Angels is not guided by traditions, stories, speculations, or myths about angels. Heiser's study is grounded in the terms the Bible itself uses to describe members of God's heavenly host. He examines the terms in their biblical context while drawing on insights from the wider context of the ancient Near Eastern world. The Bible's view on heavenly beings begins with Old Testament terms but then moves into literature from the Second Temple period—Jewish writings from around the 5th century BC to the 1st century AD. This literature from the time between the Old Testament and the New Testament influenced the New Testament writers in significant ways. With that important background established, the book focuses on what the New Testament tells us about God's holy ones. Finally, the book reflects on common misconceptions about angels and addresses why the topic is still important and relevant for Christians today.
