2 Corinthians 7:8-9 NRS

8 For even if I made you sorry with my letter, I do not regret it (though I did regret it, for I see that I grieved you with that letter, though only briefly).
9 Now I rejoice, not because you were grieved, but because your grief led to repentance; for you felt a godly grief, so that you were not harmed in any way by us.
