13 The God of Abraham, Isaac and Jacob, the God of our fathers, has glorified his servant Jesus. You handed him over to be killed, and you disowned him before Pilate,though he had decided to let him go. 14 You disowned the Holy and Righteous Oneand asked that a murderer be released to you. 15 You killed the author of life, but God raised him from the dead. We are witnesses of this. 16 By faith in the name of Jesus, this man whom you see and know was made strong. It is Jesus’ name and the faith that comes through him that has completely healed him, as you can all see.
Peter said, God’s purpose to performing those miracles was to show Christ’s glory. Therefore anyone who gives glory to anyone other than Christ for miracles is opposing God’s decrees.
Peter mentioned “the God of Abraham, Isaac and Jacob” in order to show the people that he intended to lead them on from the old way of worshiping the true God, which they had received from their fathers.
Peter denied that he was introducing a new religion in order to draw the people away from the Law and the Prophets.
Peter said that our faith cannot come to Christ unless it is based on Christ. Unless our faith looks to Christ, we have no faith in God. Faith brought about this healing, and they would be accused of ingratitude if they did not acknowledge that faith.
