Yes, but they are extremely rare. Instantly restoring muscle tissue to the lame, instantly restoring sight to the blind, spontaneous replacement of body parts, and raising the dead from their coffins. Now those are miracle healings. And for those who claim that miracle healings are not for our day, I tend to agree for all practical purposes. I would love to witness a miracle healing first hand, but I am reconciled to the likelihood that I never will.
Most healings take place by the ordinary function of our bodies.
Medical healing is commonly used where natural healing is difficult or impossible. Miracle healing is possible, but exceedingly rare. I bring it up as the last topic for discussion because I want to fashion a definition by first describing what it is not. Natural, medical, and psychosomatic healing might be involved in instances of divine healing, but the purpose is much broader. Divine healing does not take place in order to make the individual feel better.
