2 Corinthians 7:8-9; 2 Corinthians 7:12-13

8 If my letter made you uncomfortable, I'm not sorry. But since my letter did make you uncomfortable for a while, I was sorry. 9 But I'm happy now, not because I made you uncomfortable, but because the distress I caused you has led you to change the way you think and act. You were distressed in a godly way, so we haven't done you any harm.
12 So, when I wrote to you, I didn't write because of the man who did the wrong or the man who was hurt by it. Rather, I wrote because I wanted you to show your devotion to us in God's sight. 13 This is what has comforted us. In addition to being comforted, we were especially pleased to see how happy Titus was. All of you had put his mind at ease.
