Acts 14:21-23

When they had preached the gospel to that city and had made many disciples, they returned to Lystra and to Iconium and to Antioch, strengthening the souls of the disciples, encouraging them to continue in the faith, and saying that through many tribulations we must enter the kingdom of God. And when they had appointed elders for them in every church, with prayer and fasting they committed them to the Lord in whom they had believed.
