You may think that the examples that I have linked to are extreme and represent only a small fringe of Pentecostal Churches. While there may be some Pentecostal Churches that are more laid back that these, two facts remain: one, most Pentecostal Churches either behave this way or see this behavior as a powerful move of God's Spirit working in His people. Two, even the small number of Pentecostals that do not like this behavior know that they have no basis for judging it to be wrong because of their theology. Once you open the door to extra biblical revelation, and the mystical view of feelings, impressions, emotions, and proceed along those lines, you cannot judge what others experience. How could you?
Pentecostals are completely obsessed with dreams, visions, prophecies, God speaking to them, healings, miracles and such. This thinking occupies most of their focus. If Hays is unaware of this, then it means he doesn't know a lot of Pentecostals. Most is not all, I realize. But I have been around Pentecostals for years over a broad geographical range. To deny this is to display one's ignorance of the Pentecostal community.
