I will note that Mark 16:9-20 is not considered canonical by most conservative Bible scholars, and that is where you got the verses from.

Additionally, your rhetoric is just ordinary, Pentecostal/charismatic nonsense.
I would just as soon go to a witch doctor as a charismatic/Pentecostal service.
I wouldn't do either, but it's basically on the same level.
By the way, I asked a charismatic friend of mine for a good example of a faith healer. He is a reasonably intelligent guy. He recommended me to this guy, Bob Larson.
He charges 295 to exorcise demons from people on Skype.
Is that the best you guys can do?
LOL
He submits potential demoniacs to a long questionairre to ascertain whether they have a demon. Then he proceeds to have people hold them down and presses the Bible against their forehead, and commands the demon (s) to come out.
Now, where in the world did you find Jesus submitting potential demoniacs to a questionairre?
Are we really to take guys like this as credible?
