The gospel was preached in Acts 2:22-24. The conclusion in verse 36, the agonizing question in v. 37 and then the graphic answer, showing the tie between the death, burial and resurrection of Jesus and the necessary response by the inquirers. The commands and promises in Acts 2:38 do not stand in isolation. Jesus is the centre and circumference of our obedience to the gospel. The sacrifice of Jesus, and that alone, gives meaning and satisfaction to the sermon and promises of Peter.
