Writing a book on demonology is a risky business, because you will always find enough “enemies” as well as “friends.” To one of the most sensitive, thus often avoided, theological question, the author’s answer is an affirmative “yes,” that believers can have an unclean spirit. Now this is good enough to turn many people off. However, not so fast.
Even if many (including myself) have a fundamental disagreement to the author’s belief/thesis, this book contains an exhaustive amount of valuable information, especially two long lists of potential objections: logical (24 items, ch. 5) and biblical (56 items, ch. 6). He responded to each one of them. For me, even these lists alone provide valuable information as they are gathered in one place for the first time, and would make a copy of this book worthy. Also uniquely valuable is the History of Exorcism (ch. 10), again perhaps the very first in this magnitude.
This book is also quite different from many popularly know third wave authors who propose many “how-to” stuff. Nor is the book fadded with plenty of stories. This volume mainly deals with biblical, theological and historical arguments to support the author’s thesis.
It is expected that the author comes from a predetermined firm conclusion, thus, making his arguments consistently one-sided, obviously leaving no room for any valid counterarguments. But this is how a good book is written (although it will be the readers to decide on this, not me): to call for a serious dialog, discussion and debate, and even a response to the same “objections” from a radically different perspective of beliefs.
Do not let the academic qualification of the author fool you. The author has only a B.A., his serious and diligent work can shame many graduate and post-graduate degree holders who have never taken time to make a serious contribution like this.
This book sermons a loud call for an equally serious and exhaustive response.
