2 Corinthians 7:8-12 New Revised Standard Version Catholic Edition (NRSVCE)
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. 11 For see what earnestness this godly grief has produced in you, what eagerness to clear yourselves, what indignation, what alarm, what longing, what zeal, what punishment! At every point you have proved yourselves guiltless in the matter. 12 So although I wrote to you, it was not on account of the one who did the wrong, nor on account of the one who was wronged, but in order that your zeal for us might be made known to you before God.
