Warren Wiersbe is one of the best authors in Christendom. This book is not just information but also impartation. It's so important that the believer is not ignorant to the devices of satan. This book equips us to be strong in our pursuit of Christ and enables us to resist the wiles of the devil.
I have been in the exorcism/sanctification and purification work for over 17 years now. There is much that is learned out in the field, but learning from others via book form also lends powerful and trust-building insights into this work. Also recommended for the Deliverance book shelf. The Power of Divine: A Healer's Guide - Tapping into the Miracle by Tiffany Snow, and A Comprehensive Guide to Deliverance and Inner Healing by John Loren Sandford, Mark Sandford. We need to stand side by side, in Love and Faith as we battle the Fine Fight. Learn all the machinations, and Go Forth!
