Faith healing is based on the idea that some people - and some places have the unique power to cure disease and heal injuries.
Faith healers have a unique advantage over doctors who practice conventional medicine.
The patient may be cured or may show some improvement after meeting with a faith healer. The benefit could occur through the natural progression of the illness or through the poorly understood experience of spontaneous remission. Then, the healer typically declares that the patient failed to have the faith necessary for the healing process to work. Faith healers do not usually claim responsibility for failure. Revivalist preachers, who are seen on paid television programs or travelling from city to city, provide the best known type of faith healing.
