2 Corinthians 7:9-11
English Standard Version
10For godly grief produces a repentance that leads to salvation without regret, whereas worldly grief produces death.
11For see what earnestness this godly grief has produced in you, but also what eagerness to clear yourselves, what indignation, what fear, what longing, what zeal, what punishment! At every point you have proved yourselves innocent in the matter.
