Incorruption means blessing

Paul proclaims to his Jewish audience that the gospel which he preaches is the fulfillment of the promise made to the fathers. That promise is the bodily resurrection of Christ prophesied of in Psalm 2:7 which was fulfilled through God raising Jesus from the dead. Expounding the meaning and significance of this fulfilled promise, Paul explains that Christ's resurrection was unto incorruption and that means that the holy and sure blessings of David (Isaiah 55:3) are now available to everyone who believes in Jesus.
