After they had proclaimed the good news to that city and had made many disciples, they returned to Lystra, then on to Iconium and Antioch. There they strengthened the souls of the disciples and encouraged them to continue in the faith, saying, ‘It is through many persecutions that we must enter the kingdom of God.’ And after they had appointed elders for them in each church, with prayer and fasting they entrusted them to the Lord in whom they had come to believe.
Then they passed through Pisidia and came to Pamphylia. When they had spoken the word in Perga, they went down to Attalia. From there they sailed back to Antioch, where they had been commended to the grace of God for the work that they had completed. When they arrived, they called the church together and related all that God had done with them, and how he had opened a door of faith for the Gentiles. And they stayed there with the disciples for some time.
Acts 14:21-28 (NRSV)
...whenever you face trials of any kind, consider it nothing but joy, because you know that the testing of your faith produces endurance; and let endurance have its full effect, so that you may be mature and complete, lacking in nothing.
If any of you is lacking in wisdom, ask God, who gives to all generously and ungrudgingly, and it will be given you. But ask in faith, never doubting, for the one who doubts is like a wave of the sea, driven and tossed by the wind; for the doubter, being double-minded and unstable in every way, must not expect to receive anything from the Lord. (James 1:2-8 [NRSV])
