“Then Peter said, Silver and gold have I none; but such as I have give I thee: In the name of Jesus Christ of Nazareth rise up and walk. And he took him by the right hand, and lifted him up: and immediately his feet and ankle bones received strength. And he leaping up stood, and walked, and entered with them into the temple, walking, and leaping, and praising God.” Acts 3:6-8 (KJV)
Peter and John, the apostles of Jesus Christ were going into the temple at the time of prayer, and there was a lame; a crippled man, at the gate begging for money, in order that he might live.
Too many times emphasis is put on the miracle, rather than the Giver of the grace of the miracle. In this case, as in the case of all true miracles the Giver is God in and through His Son Jesus; and in the above situation through the Holy Spirit in Peter and John.
The greatest miracle that has happened to me is the day Jesus became my Lord and Savior as He gave me grace to believe that His Son Jesus died on the cross for my sins, was buried, and arose bodily from that grave. He lives today.
That is the message of this event in Acts. Jesus is alive. He is being preached to His own people, and some are receiving the gospel of Christ as the Spirit of God opens their blinded eyes, and heals their lame feet.
Note the words of Peter as he preaches…
Ye are the children of the prophets, and of the covenant which God made with our fathers, saying unto Abraham, And in thy seed shall all the kindreds of the earth be blessed. Unto you first God, having raised up his Son Jesus, sent Him to bless you, in turning away every one of you from his iniquities.” Acts 3:25-26
