Peter and Paul went into trances in Acts. In the garden, then Jesus said, "I AM" the troops fell down.
Is it wrong to pray for someone with a short leg. It's not the most impressive healing, since you could pull shoes or slide legs or pull a leg or something like that. But why would it be wrong to pray for a short or long leg? And if it gets healed, should we label it a trick?
Who do you have in mind who does that?
Seems to be common with some 'prosperity' folks. Belief in healing extends a lot further than the 'prosperity gospel' movement.
Who in the Charismatic movement tells people to throw away their pills? Even Benny Hinn says not to do stuff like that, and says to go get checked out at the doctor. There are some individuals who do that. I knew one guy, a young guy at the time, who had back problems and a drug and drinking problem, and a heavy prescription. He had repented, and then he was praying about his back. He did that. He got rid of his pills. I think he threw them in the trash. After he did that, he said his back pain stopped. But preachers who pray for healing, in my experience, don't generally tell people to through their pills away.
They may have done that more in the faith-cure movement, among some of the Holiness churches, and in certain types of churches in the early Pentecostal movement. The Pentecostal Holiness churches used to be against going to doctors. The Congregational Holiness split off from it partly over believing it was okay to go to doctors. Of course, when the faith cure movement was going on and even into the early Pentecostal movement, going to a doctor was taking your life in your hands. In the 1800's, doctors finally stopped delivering babies and treating wounds with bacteria on their hands after they touched the last patient. But even in the early 1900's, they give out cocaine and opium based products, which you could also buy in all kinds of tonics back then.
Nowadays, Pentecostal Holiness people will go to the doctor. And in the Pentecostal and Charismatic movements, not telling people to throw out their meds is the normal stance on the issue. The unbeliever in the video who convinced the scuba instructor to do false prophecy and fake healings believed a stereotype.
