Full of the Holy Spirit and faith to preach Gospel

Acts 11:19-30
Those who had been scattered by the persecution in connection with Stephen traveled as far as Phoenicia, Cyprus and Antioch, telling the message only to Jews. however, men from Cyprus and Cyrene, went to Antioch and began to speak to Greeks also.
The church at Jerusalem sent Barnabas to Antioch. He was a good man, full of the Holy Spirit and faith and a great number of people were brought to the Lord.
Then Barnabas went to Tarsus to look for Saul, he brought him to Antioch. So for the whole year Barnabas and Saul taught great number of people. The disciples were called Christians first at Antioch.
It was said that a severe famine would spread over the entire Roman world, The disciple decided to provide help for the brothers living in Judea. They sending their gift to the elders by Barnabas and Saul.
Things are moving in the north, at Antioch, third largest city in the world, busy commercial centre and capital of the Roman province of Syria.
The warm response of the Greeks to the Christian message leads the Jerusalem church to dispatch Barnabas to Antioch. He in turn tracks Saul down at his home city of Tarsus. And the stage is set for the next great advance.
