This book was a clear and concise study on the phenomenon of speaking in tongues. The author clearly did his research, and this is written in a very loving way. However, that does not negate the message of the book--speaking of tongues, as in the charismatic movement is in error. The scriptures that the modern charismatic movement use to justify their beliefs are analyzed within the context of the ENTIRE Bible and shown to clearly be in error. This book was very informative and cleared up my ideas on the charismatic movement.
