Should We Do Different “Things” to Necks, Spines, Arms, Pelvises and Legs Depending on the Condition?

Nothing in Scripture supports this idea.  You should be very wary of any teaching that is not backed up with Scripture.  I’m quite aware of the peculiar teaching alluded to by the question.  We don’t see any verse that says, “And Bar-Andrew, the son of Andrew, came to Jesus with the flu, and Jesus did The Arm Thing and then The Neck Thing to him and healed him.  Then Pheobe, the daughter of Ralph, came to Jesus with a bladder infection, and Jesus did The Pelvic Thing and The Leg Thing to her and told her she was healed.”

Everything you need to know to do healing ministry is in the Bible.  You do not need any other book – including this one – to be thoroughly equipped for every good work (2 Timothy 3:16-17).  Other books are useful only to the extent that they teach you the Word and how to apply it.

One danger healing evangelists can get into is trying to make the particular way that God uses them the standard for the entire Body of Christ.  One minister said he felt power bounce between his hands if someone had a demon.  Do we make that the standard – see if power bounces between your hands to see if a demon is present?  God might actually show you the demon.  But that doesn’t mean that everyone else has to actually see demons.

Someone who flows in the word of knowledge might try to teach someone else that you get up there and allow the Holy Spirit to use you by supernaturally calling out healings in the audience.  God uses some people in the word of knowledge, but someone else might simply lay hands on people and have gifts of healings and the working of miracles flow through his hands.  God likes variety.  No two ministers will be able to minister in exactly the same way.  God did not create you to be a copy of anyone else, so you should not attempt to be a copy of someone else.

If you’re comfortable having God use you while doing “things” to people based on a huge list of memorized conditions with corresponding “thing” combinations, don’t let me stop you if it works for you.  But don’t think that such lengthy memorization is necessary to minister healing, because no one in Scripture did the “thing” thing, and plenty of miraculous healings were done other ways.
