“Now when I came to Troas for the gospel of Christ and when a door was opened for me in the Lord, I had no rest for my spirit, not finding Titus my brother; but taking my leave of them, I went on to Macedonia.”
(2 Cor. 2:12-13)
This is Paul telling the Corinthians Christians that his love for them was all-consuming. In this section (2 Cor. 2:12-17) e explains why he had previously used such a severe tone in his prior letter to the Corinthians – a letter not included in the canon of Scripture. But instead of writing a series of reproofs to the church (as they deserved), instead he gave several statements that explain his all-consuming love of genuine gospel ministry.
In Troas there was an open door – likely, the start of a church. But Paul passed over the city so he could meet Titus on his way back from Corinth with news. Had the Corinthians repented, or were they headed for apostolic discipline?
Here’s Paul point – a genuine man of the gospel cannot just move in and plant the gospel with another people and leave those he has ministered to before – without awful grief of heart.
