My wife happened across this video on another site, and we both watched intently at the seeming insanity taking place.
Kenneth Hagin (1917-2003) is the Pentecostal preacher in the video. What on earth causes people to act this way? Of course, believers will say that what causes this is not of this earth, but is the holy spirit™. I think they’re all more than a little bit nuts, to be honest about it.
[I had to replace the video with another showing the original plus some added content. The original video owner’s account no longer exists.]
