I have seen many pentecostals seek an experience rather than what the Bible really teaches.I believe in tongues some say because I experienced it.Some pentecostal preachers and teachers tell their congregations how to speak in tongues by word or tracts.If its of God the Spirit will get that tongue to flowing but sadly its not that way.

Many cults speak in tongues and it sounds just like some mainline pentecostals speaking .Kenneth copeland was caught praising satan in english between speaking in tongues and yep copeland looks like a demon.
