This book discusses the gross misrepresentation of "speaking in tongues" that many Pentecostals and Charismatics tout as proof of "baptism of fire". Not only that but it goes in depth about the role of such "signs and wonders" during the apostilic age. Most importantly it discusses the need for the supremacy of Scripture as the standard by which we judge something as "of God" or "not of God". Great read for those who have watched in curiosity as someone began running up and down the church building babbling gibberish.
