Timothy was well thought of by the believers in Lystra and Iconium,
so Paul wanted him to join them on their journey. In deference to the Jews of the area, he arranged for Timothy to be circumcised before they left, for everyone knew that his father was a Greek.
Then they went from town to town, explaining the decision regarding the commandments that were to be obeyed, as decided by the apostles and elders in Jerusalem.
So the churches were strengthened in their faith and grew daily in numbers.
Next Paul and Silas traveled through the area of Phrygia and Galatia, because the Holy Spirit had told them not to go into the province of Asia at that time.
Then coming to the borders of Mysia, they headed for the province of Bithynia, but again the Spirit of Jesus did not let them go.
So instead, they went on through Mysia to the city of Troas.
That night Paul had a vision. He saw a man from Macedonia in northern Greece, pleading with him, "Come over here and help us."
So we decided to leave for Macedonia at once, for we could only conclude that God was calling us to preach the Good News there.
