On this Resurrection Sunday, we examine the very first preaching of the resurrection of Jesus as the Messiah which took place on Pentecost day in Acts 2. In that sermon, Simon Peter powerfully demonstrates the resurrection of Jesus as the Christ from the four testimonies of God, Scripture, witnesses, and the Holy Spirit. Most astonishingly, Peter extends the living testimony of the Holy Spirit well beyond his own audience in Jerusalem in that setting, to all whom the Lord will call to Himself (v 39). Peter concludes his sermon with the call of the gospel unto repentance, baptism, forgiveness of sins, and the Holy Spirit.
