2 Corinthians 7:8-9

I know I distressed you greatly with my letter. Although I felt awful at the time, I don’t feel at all bad now that I see how it turned out. The letter upset you, but only for a while. Now I’m glad—not that you were upset, but that you were jarred into turning things around. You let the distress bring you to God, not drive you from him. The result was all gain, no loss.
