I voted "for" healing ministries, but as that term may mean any number of things, I thought I should explain.
It seems to me we should be in favor of people being healed. That is why we go to doctors after all. And Jesus miraculously healed a lot of people, so healing surely can't be wrong by default. It's also worth noting that Jesus was accused of being occult in his healing practices, and that some of the things he did (spitting on blind eyes, sticking finders in deaf ears, etc.) are more like the sorts of things shamen do than what good Jewish boys ought to be doing. The outward appearance of Jesus' healing work had more in common with back-street magicians than with doctors or priests.
I don't see any reason healing needs to happen in a "healing meeting," and if Craig Keener's excellent two volume work,
Miracles: The Credibility of the New Testament Accounts, is any indication, most miraculous healings
don't happen in those meetings; they happen in the relative anonymity of peoples regular daily lives.
I have a friend who had a large benign tumor on her ovary. Because of the size of the tumor and the risk of it twisting and causing incredible pain resulting in an emergency operation, the doctor wanted to proactively operate and remove the ovary along with the tumor. At a home bible study, someone told my friend they "didn't want to freak her out but they thought they had the gift of healing." They prayed for her and the next time the doctor scanned the tumor it was gone. It seems to me the person who prayed for my firnd might have a healing ministry, but it's nothing like what most of us picture when we hear those words.
If Jesus miraculously heals multiple people through the faithful obedience of a person who quietly lays hands on the sick without seeking any fame or fortune, I think that's fantastic. So yes, in that context, I am absolutely in favor of healing ministries.
