This book turns my whole perspective about demons around. It is an excellent book. I recommend this for every Christians.
The only negative is that Prince hold a view that demons are embodied pre-Adamic race and not fallen Angels. Though he does have his point there because the Bible did not make clear enough where demons come from. However, he did point out that most Christians do believe that demons are fallen angels. Either way this does not have any negativity on the deliverance ministry.
The positive note is that Prince really protray well of the basic for readers to prepare and understand deliverance from demons. I recommend this for all Christian readers. Still be extremely careful about reading on deliverance.
