Then they passed through Pisidia and came to Pamphylia. And when they had spoken the word in Perga, they went down to Attalia, and from there they sailed to Antioch, where they had been commended to the grace of God for the work that they had fulfilled. And when they arrived and gathered the church together, they declared all that God had done with them, and how he had opened a door of faith to the Gentiles. And they remained no little time with the disciples. (Acts 14:24-28)
In their report back to the church in Syrian Antioch Paul and Barnabas tell them what things God had done through them. They said this correctly, because none of us can make disciples; the conversion of persons is a spiritual work which only God’s Holy Spirit can do.
So, notice how the church leaders had been praying, how God had answered their prayer, and how Paul and Barnabas went in obedience to God after the further prayer and fasting of all of them (see Acts 13 verses 1-3).
