Paul does not lose heart even in the midst of sufferings and conflicts for he knows that as a minister of the New Covenant his success is guaranteed!
In 2 Corinthians Chapter 3 we find the he glorious ministry of the Spirit is Paul’s confidence and reason for his boldness. Paul’s legitimacy is based on his being a minister of the New Covenant.
The Corinthians are Paul’s proof of God’s hand on his ministry. They are impressed on Paul’s heart and mind. They cannot question his legitimacy without bringing into question their own.
This passage gives us a snapshot of Paul’s heart after he had written the severe letter to the Corinthian Church. He is anxiously waiting for Titus who delivered the letter praying for a good report.
Way too often we seek to terminate relationships (the source of pain/disputes) too quickly thinking that is easier. Confrontation is never fun, but it is a sign of love and obedience.
