2 Corinthians 7:8-9

8For aeven if I made you grieve with my letter, I do not regret it—though bI did regret it, for I see that that letter grieved you, though only for a while. 9As it is, I rejoice, not because you were grieved, but cbecause you were grieved into repenting. For you felt a godly grief, so that you suffered no loss through us.
