This book was an enormous help to me. It showed me that I didn't have to worry all the time that I was letting my standing with God slip somehow, just because the emotional displays I saw in the charismatic church were not a reality for me. I'm really a pretty staid individual, and that's alright. The exposure of the doctrinal problems the movement suffered from was a real eye-opener, too, especially the link between Kenneth Hagin and E.W. Kenyon, the New Thought trancendentalist. Highly recommended.
