I have been researching for a new book to be published in 2013. Lots of varying perspectives on the topic. I'm quite surprised at the amount of books which propogate unbiblical methods of dealing with the enemy. Seems as though Satan himself is in the book writing/publishing business! However, I have read numerous solid books and have found several authors that I enjoy.
I am totally recommending Spiritual Warfare and The Christian Soldierby D.Martin Lloyd-Jones, Spiritual Warfare by Jerry Rankin and The Invisible War by Donald Grey Barnhouse. If one had these books in their library, I believe that one would be well read on the topic..
