2 Corinthians 7:5-9

When we arrived in Macedonia, there was no rest for us. We faced conflict from every direction, with battles on the outside and fear on the inside. But God, who encourages those who are discouraged, encouraged us by the arrival of Titus. His presence was a joy, but so was the news he brought of the encouragement he received from you. When he told us how much you long to see me, and how sorry you are for what happened, and how loyal you are to me, I was filled with joy! I am not sorry that I sent that severe letter to you, though I was sorry at first, for I know it was painful to you for a little while. Now I am glad I sent it, not because it hurt you, but because the pain caused you to repent and change your ways. It was the kind of sorrow God wants his people to have, so you were not harmed by us in any way.
