Well written book from a biblical context concerning what the scriptures say about spiritual warfare. The book exposes non-biblical theories of spiritual warfare that have arisen over the past 50 years in the church. Powlison goes back to the basics of biblical interpretation: consider the text within its context. What do the scriptures say? Much of the modern view of Satan and his demons has been sensationalized and become "main-stream" truth with many Christians. I wish this book was still in print or available in a digital format.
