(12) After leaving Ephesus, I traveled to the city of Troas to proclaim the gospel (good news) of Christ. When I arrived, I discovered that the Lord had opened a wide door for my ministry, (13) but I still had no peace in my spirit because I did not find my brother Titus there, as he had not yet come from Corinth. So I said goodbye to the Troas church and took a boat across the Aegean Sea to the Roman province of Macedonia (see Acts 20:1).
