Acts 3:13
The God of Abraham, and of Isaac, and of Jacob, the God of our fathers, hath glorified his Son Jesus; whom ye delivered up, and denied him in the presence of Pilate, when he was determined to let him go. The God of Abraham, and of Isaac, and of Jacob, the God of our fathers, hath glorified his Son Jesus; whom ye delivered up, and denied him in the presence of Pilate, when he was determined to let him go.
Peter spoke to the men of Israel at the temple to explain why healing power still worked through Jesus after his death, when the priests expected miracles to cease and the people wondered how a man lame from birth was made strong. He directly charged his hearers with handing Jesus over and disowning him before Pilate when Pilate was resolved to release him. The God of Abraham and of Isaac and of Jacob, the God of their fathers, glorified His Son Jesus. That glorifying meant God raised Jesus from the dead and exalted him, vindicating him against his rejection so that as risen and ascended his work went on. The strength given to the lame man came not from the apostles' own power or holiness but from Jesus himself, received through faith in his name and merits.
Peter's Temple Address
Peter spoke to the men of Israel to explain why miracles continued after Jesus was crucified. The priests had expected miracles to cease with His death, while the people wondered where His followers got power to heal the man lame from birth. He denied that the cure came by the disciples' own power or holiness.
At the temple gate the cripple had hoped to be healed by Jesus but found that Jesus had been put to death. Yet healing still came afterward through Jesus' name.
The address directly accuses the hearers of delivering up Jesus and denying Him in the presence of Pilate. Pilate was determined and resolved to let Him go and release Him, but they denied Him before Pilate even then. It places responsibility for His rejection on them, charging them with rejecting, crucifying, killing, and murdering the Son of God. Whom they rejected and crucified, God raised from the dead.
God Glorified His Son
The God of Abraham and of Isaac and of Jacob, the God of the fathers worshiped by Israel, glorified His Son Jesus. That God is the God worshiped by Abraham, Isaac, Jacob, and Israel, and He glorified Jesus as His Son, as the Son of the infinite God. His glorifying of Jesus means He raised Jesus from the dead, exalted Him, and vindicated Him in contrast to His rejection by men. As thus risen and ascended, Jesus was proved exalted, and His work continued afterward.
It was Jesus, not the apostles' own power or holiness, who was the source of the miracle-working power that made the lame man strong. That healing was done through faith in His name and through His merits, and the power of that name was received through faith in Jesus whom God raised from the dead. After the resurrection and ascension the disciples bore bold witness to Him as the Son of God. That bold testimony was given through the Holy Spirit, reflected His words and works, proclaimed His resurrection, and carried forward His teaching and the proclamation that He was risen and ascended and the source of the power by which they healed.
His suffering fulfilled what God had foretold through the prophets. He had been rejected and crucified in part because His purity and holiness rebuked selfishness and corruption.
