What did Peter say in Acts 15 about God choosing him to reach the Gentiles?

Les explains that Peter wakes up in Acts 15 a long time after the earlier event and recalls that a good while ago God made choice among the Jewish believers that the Gentiles by his mouth should hear the Word of the Gospel and believe. After Peter's explanation, the multitude kept silence and gave audience to Barnabas and Paul, who declared what miracles and wonders God had wrought among the Gentiles. James, who was moderating the meeting, then said that Simeon or Peter had declared how God at the first, at the house of Cornelius, visited the Gentiles to take out of them a people for His name. Les identifies that people as the church, which is His body, being formed for over 1900 years by predominantly Gentiles called out from paganism and becoming members of the Body of Christ. Les also notes that when this began, the Jews became envious and opposed it everywhere Paul went, and God put blindness upon the nation, though He still deals with the Jew nationally and personally.
