I had a Pentecostal schoolfriend who attended an AOG church. My apologies to any Pentecostals here, but I feel they are more of a cult than the Watchtower. They definitely employ the BITE system.
I feel my schoolfriend was the consummate cult leader. He had me believing that they abounded in signs and miracles and that he witnessed fantastic happenings. That, along with the chararisma and emotional appeal, seduced me into joining him for a few months. He had me "speaking in tongues" and so forth. He kept telling me, "Don't think, just believe."
In retrospect, I believe he may have been a compulsive liar who made up stories on the spot and actually believed them himself. There were no signs or miracles. Speaking in tongues was a sham…and according to Steve Hassan, a thought-stopping technique.
I understand the need to fellowship with others who believe in Christ, but caution is definitely in order. Proceed with eyes wide open. Don't be seduced by emotional control or chararismatic leaders.
