Peter said to the lame man "'in the name of Jesus Christ the Nazarene--walk!'" (Ac 3:6). "On the basis of faith in His name, it is the name of Jesus" (:16) that healed. It is "the faith that comes through Him" (:16) . . . according to Jesus' authority by means of the method of faith. Peter stated "by this name the man stands here" (4:10). The rulers had asked, "'By what power, or in what name, have you done this?'" (:7). Remember that Jesus had said ""Whatever you ask in My name, that will I do'" (Jn 14:13). Peter then said, "'What I do have I give to you'" (Ac 3:6). It was a "'noteworthy miracle'" (4:16).
The rulers wanted to know by what power or name the man had been healed. "God anointed Him with the Holy Spirit and with power" (Ac 10:38). To the "twelve disciples he gave authority . . . to heal every kind of disease" (Mt 10:1). "God was with Him" (Ac 10:38). Peter said, "'Aeneas, Jesus Christ heals you'" (9:34). "Immediately he got up" (:34) "Immediately the man became well" (Jn 5:9). "It is God who is at work in you" (Php 2:13) by the "Spirit of life in Christ Jesus" (Ro 8:2) that "dwells in you" (:11). You are "the temple of God" (1Co 3:16) and "He who raised up Jesus Christ from the dead will also give life to your mortal bodies through His Spirit who dwells in you" (Ro 8:11).
