Acts 14:21-23

And when they had preached the gospel to that city and made many disciples, they returned to Lystra, Iconium, and Antioch, strengthening the souls of the disciples, exhorting them to continue in the faith, and saying, “We must through many tribulations enter the kingdom of God.” So when they had appointed elders in every church, and prayed with fasting, they commended them to the Lord in whom they had believed.
