Acts 3:16

The proclamation portion of Peter’s sermon expounds "the name of Jesus" (cf. Acts 3:6). The "name" of Jesus summarizes everything about Him here as elsewhere in Scripture. Peter attributed the beggar’s healing to the power of Jesus and to the man’s trust in what he knew about Jesus. Jesus had given him faith. If the beggar had had no confidence in the deity and divine power of Jesus, he would not have responded to Peter’s invitation to walk (Acts 3:6). His response demonstrated his faith. Undoubtedly this man had seen and heard Jesus when He was in the temple. Jesus had given him "perfect health."

"The Christian knows that so long as he thinks of what I can do and what I can be, there can be nothing but failure and frustration and fear; but when he thinks of ’not I, but Christ in me’ there can be nothing but peace and power." [Note: Barclay, p. 31.]
