They want to go to an alternative healer and in one session have their illness cured. Of course, they spent months and months going to medical doctors and weren't healed. Spiritual healing is not more miraculous. But it's not hocus-pocus. I would be happy to not be needed anymore because people could do it for themselves.
Surgery can remove a tumor but it is the body that heals.
The body heals the surgical wound. Without that healing, a person would die of the surgical wound. The same is true with medicine. There are no magical answers in medicine, either. Medicine has many wonderful things to offer.
