Acts 16:8

and they, passing by Mysia, came down to Troas.

The zeal of Paul knew neither weariness nor rest; he was ever active for his Lord. As he traveled through the cities where congregations had been founded through his own efforts or those of disciples that had become missionaries, he and his companions delivered to them all the resolutions which had been fixed by the apostles and elders in Jerusalem. All the congregations were admonished to observe these decrees, although they were directed only to the congregations in Syria and Cilicia. Uniformity of practice, especially in such important matters, is to be recommended very highly for churches of the same confession. In this way the congregations everywhere were established in the faith; the encouraging admonitions of the apostle and his companions strengthened their faith. And a second result of the visitation was that the churches increased in numbers day by day. Thus Paul made the rounds of the congregations in this entire district, which was racially Phrygian, but administratively Galatic: Iconium, Antioch, and all the stations that were connected with these cities, He may even have extended his labors into North Galatia, though recent investigations seem to oppose this assumption. Many congregations sprang into existence under his labors in Galatia, 1 Corinthians 16:1, and he was always united with these disciples by the ties of a fervent love. Having carried out his missionary labors to the extent which he had intended in this province, Paul planned next to visit the province of Asia, a maritime province in southwestern Asia Minor, on the Aegean Sea. But he was hindered, prevented, from speaking the Word in this province by the Holy Spirit. This was done either by an inner revelation or by a prophetic intimation which permitted of no misunderstanding. So they journeyed to Mysia, into the borders of this province, west of Phrygia, and there made the attempt to turn northward into Bithynia, a province on the Black Sea. But again the Spirit of Jesus intervened and hindered them. Note: The Holy Spirit is the Spirit of Jesus Christ, Romans 8:9, as well as the Spirit of the Father, Matthew 10:20. Nothing now remained for them to do but to travel due west to Troas, a seaport on the Aegean, opposite Greece. It is the Lord that directs and governs the course of the Gospel on earth. All the matters and circumstances are arranged by Him in such a way as to serve the Gospel according to His will.
