When I hear the word healing, I think of it in medical terms. I think of doctors who diagnose sickness, treat injuries, research diseases, and work to prevent the onset of pain and illness. I think of state-of-the-art cardiac units and Doctors Without Borders. I think of amoxicillin (despite the fact that it gives me hives).
When I hear the phrase Christian healing, however, my mind switches channels to the worst of what religious broadcasting has to offer. A lot of hucksters out there dangle the promise of miraculous cures to those who would just summon the faith to buy them. There is never a lack of suffering in this world, and with the right balance of illusion and charisma, con artists can make big bucks by exploiting it.
