“We are witnesses of everything he did in the country of the Jews and in Jerusalem. They killed him by hanging him on a cross, but God raised him from the dead on the third day and caused him to be seen. He was not seen by all the people, but by witnesses whom God had already chosen — by us who ate and drank with him after he rose from the dead. He commanded us to preach to the people and to testify that he is the one whom God appointed as judge of the living and the dead. All the prophets testify about him that everyone who believes in him receives forgiveness of sins through his name.” (Acts 10:39-43)
Peter’s testimony to the household of Cornelius echoes the apostolic witness recorded elsewhere in Acts. I think in particular of Peter in Acts 2 and Paul in Acts 13. Here is what I hear in these proclamations.
The resurrection of Jesus is a promise and a sign. It is a promise of a future resurrection of all humanity — the wicked and the righteous. It is also a sign that Jesus of Nazareth was and is the Son of God, the messiah, Christ. He is the one who will judge the living and the dead at the end of the present age. He is also the one through whom we receive forgiveness for our sins.
In the witness of the Book of Acts, those who receive this teaching receive the gift of the Holy Spirit. This is a present gift offering us peace, joy, and power to trample down sin. The Holy Spirit gathers us into a body and teaches, nurtures, and disciplines us.
As Christians, we are called to live by the Spirit and in accord with the will of God, so that at the resurrection we will be found to have worthily run the race set before us. In our ears, the Lord will say, “Well done, my good and faithful servant.”
This is, I hope, a fair summary of the apostolic preaching recorded in Acts. If it is, I wonder how it is heard today. I wonder how well it accords with what we preach and teach.
