24 Then they passed through Pisidia and came to Pamphylia. 25 And when they had spoken the word in Perga, they went down to Attalia, 26 and from there they sailed to Antioch, where they had been commended to the grace of God for the work that they had fulfilled. 27 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. 28 And they remained no little time with the disciples. (Acts 14:24-28 (ESV)
So the first mission trip is over. Paul has been gone at least one winter and two summers. Now he is back in Antioch. Now he and Barnabus are doing what all missionaries do. They are telling the home congregation how the trip went, sharing the successes and failures.
They stay no little time with the disciples. I love the understatement here. Paul stays for some time. It is needed. Time for reflection, recovery, time to come to grips with what he has learned. Those who are sent to teach learn more than they teach as a rule. He has learned what to expect from the gentiles as he preaches the gospel. He has learned what to expect from his compatriots. Sometimes this sort of thing is necessary. Paul had success on his mission trip, but we learn from our failures more than our successes. He will build on what he has learned as he gets back to it shortly.
