To be honest, I see no other way to dismiss it.
Faking? How can you fake becoming as white as a ghost and breaking out in sweat and the producing an unnatural male voice? Do the voodoo people fake what they do? Doesn't seem like it to me. But if you prefer to think it was faked that is your right to an opinion.
Identical?
Peter acted identical to the people in the King Kong film excerpt that he added the furiously rolling around on the ground?
Please show me where Peter became drenched in sweat, began suddenly trembling, dropped to the ground, started rolling on the floor, making garbled sounds, showed only the white of his eyes, and acted like those people in the King Kong film.
BTW
It isn't only one person. They began behaving that way in church. Go on the internet and you can see them doing the same things during their meetings. What would a psychiatrist say about that behavior? Better yet, what would Jesus say?
