After Pentecost, Peter's sermons are all thesame and there's not an "I" in any of them. "This Jesus whom you crucified," Peter preaches again and again, "God raised Him from the dead.Repent and believe."Peter believes that the sheer miraculous gratuity of God's call- the very fact that God calls people like him or...you- is the only corroboration we require that Jesus Chris is not dead.
