Acts 3:6 But Peter said, Silver and gold I do not possess, but what I have, this I give to you: In the name of Jesus Christ the Nazarene rise up and walk. (8) And leaping up and about, he stood and began to walk, and he entered with them into the temple, walking and leaping and praising God. (12) And when Peter saw this, he replied to the people, Men of Israel, why are you marveling at this?... (13) The God of Abraham and Isaac and Jacob, the God of our fathers, has glorified His Servant Jesus, whom you delivered up and denied in the presence of Pilate, when he had decided to release Him. (16) And upon faith in His name, His name has made this man strong....
Peter and John did a miracle, and the people paid their attention to it. But in his speaking Peter turned the attention of the people from the miracle to a Person, to the Lord Jesus. Although Peter and John had performed a miracle, Peter did not talk about the miracle.
Instead, he used the miracle as a basis to turn his audience to Christ. He turned the people's attention from the healing to the Healer. Peter's message was based on the miracle of the healing of the lame man.
However, it was not Peter's burden to talk about divine healing. Rather, his burden was to propagate Christ. He was burdened to speak forth Christ, to speak out Christ.
Peter's burden was to speak Christ directly into others so they may become Christ's propagation to be His living members in order that Christ may have a Body on earth. First, Peter said to the lame man, "In the name of Jesus Christ the Nazarene-walk!" Then in his message he went on to say, "By faith in His name, His name has made this man strong, whom you behold and know"(v.
16). Therefore, Peter did not preach divine healing or miracles; he preached the Person of the Lord Jesus Christ.
