2 Corinthians 7:8-10

New Revised Standard Version, Anglicised

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. ¹⁰ For godly grief produces a repentance that leads to salvation and brings no regret, but worldly grief produces death.
