The God of our forefathers raised up Jesus, whom you seized and killed by hanging him on a tree. God exalted him to his right hand as Leader and Savior, to give repentance to Israel and forgiveness of sins. Acts 5.30-31
Before the Sanhedrin, the high Jewish court, Peter and the other apostles answered, for the second time, for preaching about Jesus. With courage and truth, they made clear the great acts of God, in spite of the actions of the council.
They were doing what Peter, many years later, would affirm to be the church’s mission: “proclaim the might acts” of God, 1 Pet 2.9 NRSV.
The focus of God’s work is the resurrection and exaltation of Christ. In the resurrection, God declared that Christ’s death was effective for all humanity. In his exaltation, God established him as Leader and Savior, whom all ought to follow and to whom all must submit. There would be no salvation without abandoning other gods (including one’s own opinion) and turning to Jesus.
Salvation contains several aspects or facets, but Peter, from what he makes evident in his first letter, thinks of it more in the future, “ready to be revealed in the last time” 1 Pet 1.5. He thinks especially of its eternal result.
Luke, the author of Acts, holds a special interest in repentance as a condition of forgiveness, Lk 24.47. What God did is for all, but few are will to seek it. Still, to all the Good News is offered, even to the Sanhedrin.
Praise be to the Lord for your great acts in Christ.
