Peter retells his account to argumentative Jewish believers, of the Lord telling him to open the doors of the Gospel message to the Gentiles, as well as to the Jews. Jewish believers start to obey this new mission, by the power of the Lord's Spirit working within them. Agabus gives a prophetic warning by the Holy Spirit that there was a great famine coming upon the entire Roman world, and to send relief to their brothers and sisters in Christ who were in need there. Here at Antioch, the believers were first called Christians.
