Healing and deliverance is a two person affair. The LORD works through one of his servants to heal another. In the New Testament, the disciples actually have trouble with one spirit for lack of faith; Jesus promptly rebukes them. Responsibility also lies with the person receiving healing and deliverance. The faith of the sick and maimed is required to work such a miracle. When Jesus was in Nazareth, few believed on Him. It is no coincidence that He did few miracles there.
