After Paul had seen the vision, they got ready at once to leave for Macedonia

Acts 16:1-15
Timothy joins Paul and Silas, they traveled from town to town, delivered the decisions reached by the apostles and elders in Jerusalem for the people to obey, So the churches were strengthened in the faith and grew daily in numbers.
Paul's vision of the man of Macedonia.
When they traveled throughout the region of Phrygia and Galatia, having been kept by the Holy Spirit from preaching the word in the province of Asia. When they came to the border of Mysia, they tried to enter Bithynia, but the Spirit of Jesus would not allow them to. After Paul had seen the vision, they got ready at once to leave for Macedonia.
Lydus' conversion in Philippi.
The decision to circumcise Timothy was taken in order to regularize his position as a Jew, not in order to secure his salvation. Pail had a special affection for his loyal, though timid, companion and successor. He came to regard his almost as his own son.
At Troas, close to ancient Troy. Luke joins the party for the first time, and Paul receives his call to cross to Europe. It is tempting to think that Luke was the man in Paul's dream.
In each place he visited, Paul normally went first to the synagogue. At Philippi there was simply a group of women, meeting for prayer. So the church at Philippi, whose loving, faithful support and unfailing concern would bring Paul such joy begins with the response of Lydia, a local businesswoman.
Why?
A man with mission have to abandon one and choose another one. We can't choose both. We have to take responsibility to our decision and our life. If there is not vision, can do what you want.
Jesus said your time is easy we may go anywhere at anytime.（ 約7:6 耶穌就對他們說：我的時候還沒有到；你們的時候常是方便的） John7:6 Then Jesus said unto them, My time is not yet come: but your time is alway ready.
