I liked this book, it sheds much light on demonic operations. The schemes of the devil, as well as the attributes of evil spirits and their way of attack is exposed.
I read this book twice, one time after the other. It is a difficult book to read, one that takes time because of the nature of the subject.
I agree with at least 85% of it, however it does not shed a favorable light on those Christians who manifest speaking in tounges, prophecy, etc.
The author is very conservative and that is o.k. but Charasmatic readers may find a tidbit of the author's analysis offensive.
Surely, as Christians we can look over those things we don't agree with, in order to learn more about the subject matter at hand.
