Peter, the disciple who denies that he even knew Jesus at his trial, now on the day of Pentecost (Acts 2) gives a fiery defense for the resurrection of Jesus. The people who had been in Jerusalem at the time of Jesus’ crucifixion knew what had happened, but Peter summarized it for them. Jesus performed mighty deeds and wonders and yet he was delivered up, with a plan that was part of God’s foreknowledge, killed and then God raised him up from the throes of death because it was impossible for death to hold him.
He then turns the argument by saying, you can go to David’s tomb and you will find his bones. In fact, anyone who has died and been buried you will find their bones, but you will never find the bones of Jesus because he died, but three days later he was resurrected. His tomb was empty. He wasn’t taken by grave robbers. The guards who were responsible for making sure that stealing his body didn’t happen; told the religious leaders that the resurrection did happen and they were bribed to keep silent.
It wasn’t just enough to say the Jesus was resurrected, he was seen alive with a physical body and physical wounds that they could see and touch. He ate with them. He taught them and encouraged them. This gave them boldness to tell what happened. The eye witness accounts started the church that goes on to this very day. We believe in the resurrected Jesus because of the eye witness accounts of the disciples and those who saw him. We believe.
