"The shape of the narrative in the closing chapters of Acts is also most instructive. A quick comparison with Luke's gospel reveals a close parallel: Paul, like Jesus, goes on a long journey, ending up being tried before both Jews and Romans. The equivalent of the crucifixion, however, is not Paul's own death. Luke has no intention of making Paul a second redeemer, dying for the sins of the world. The crucifixion narrative in the gospel is echoed by the storm and shipwreck in Acts; the resurrection, by the safe arrival of Paul and his party in Rome, leading to the open and unhindered proclamation of the kingdom of Israel's god, the god now revealed in the risen Lord Jesus. The gospel of Jesus advances by the same means as Jesus himself had done; the cross and resurrection are stamped upon the life of the church that bears witness to them. But the work of the church derives from that of Jesus, and is not merely parallel to it."
