Paul has a dream
6 Paul and his friends wanted to go to the region of Asia to speak God's message. But the Holy Spirit stopped them from doing this. So they travelled through the regions called Phrygia and Galatia. 7 Then they arrived at the edge of the region called Mysia. They wanted to go from there into the region called Bithynia. But the Holy Spirit of Jesus stopped them from going there too. 8 So they went quickly through Mysia, and they arrived at the city called Troas, on the coast.
9 During that night, Paul had a dream. In the dream, he saw a man from the region called Macedonia. The man stood there and he said to Paul, ‘Please, please come across the sea to Macedonia and help us.’ 10 After Paul's dream, the next morning we immediately prepared ourselves for the journey to Macedonia. We decided that God was telling us to go there. He wanted us to tell the people there the good news about Jesus.
16:10'We' is used here so it seems that Luke met Paul, Silas and Timothy in Troas.
