Acts 14:21-22

After preaching the wonderful news of the gospel there and winning a large number of followers to Jesus, they retraced their steps and revisited Lystra, Iconium, and Antioch. At each place they went, they strengthened the lives of the believers and encouraged them to go deeper in their faith. And they taught them, “It is necessary for us to enter into the realm of God’s kingdom, because that’s the only way we will endure our many trials and persecutions.”
