This article has attempted to show the relevance of faith and prayer to the healing arts. Whilst its frame of reference differs from that of the medical scientist, its application is not incompatible with conventional medical practice. It springs from a belief that all healing ultimately resides with God, who acts through divinely appointed laws to energize the natural healing processes of the body. Through faith and prayer, attunement is possible with God resulting in an energy flow to the patient. This belief is supported by scientific evidence. Faith healing supports the concept of 'healing of the whole person', and challenges the medical scientist and practitioner to develop a greater awareness of the 'unknown factors' working in recoveries of patients beyond normal medical expectation.
