Acts 3:16

16. But Peter does not stop short with this climax, terminating in the resurrection from the dead. He proceeds to prove his present power and glory by the facts which were then filling them with amazement. (16) "And his name, through faith in his name, has made this man strong, whom ye see and know. Even the faith which is through him, has given him this perfect soundness in the presence of you all." In this verse, there is one of those repetitions common with extemporaneous speakers, and designed to express more guardedly a thought already uttered. Perhaps the formula employed by Peter in the act of healing, "In the name of Jesus of Nazareth, rise up and walk," suggested to him the phraseology, "his name, through faith in his name, has made this man strong." But lest the superstitious audience might imagine that there was some charm in the mere name of Jesus, a mistake which was afterwards made by certain Jews in Ephesus, he adds, "The faith which is through him has given him this perfect soundness." The faith was not that of the cripple; for it is clear, from the description, that he had no faith. When Peter said to him, "Look on us," the man looked up, expecting to receive alms. And even when Peter told him, in the name of Jesus, to rise up and walk, he did not attempt to move till Peter "took him by the right hand, and lifted him up." He exhibited no faith, either in Jesus, or in Peter's healing power, till after he found himself able to stand and walk. We must locate the faith, therefore, in the apostles; and in this we are sustained by the fact that the exercise of miraculous power, by those in possession of spiritual gifts, was always dependent upon their faith; Peter was empowered to walk upon water; but, when his faith wavered, he began to sink, and Jesus said, "O thou of little faith, wherefore didst thou doubt?" Nine of the apostles, once, having failed to cast out a demon, asked Jesus, "Why could we not cast him out?" He replied, "Because of your unbelief." In answer to their prayers, also, many miracles were wrought, but it was only "the prayer of faith" which could heal the sick.

It must be here observed that faith was necessary to the exercise of spiritual gifts, already imparted, and that no faith, however strong, ever enabled the uninspired to work miracles. The notion, therefore, which has existed in some minds, from time to time, ever since the apostolic period, that if our faith were strong enough, we, too, could work miracles, has as little foundation in scripture as it has in experiment.
