2 Corinthians 7:10-12

God designed us to feel remorse over sin in order to produce repentance that leads to victory. This leaves us with no regrets. But the sorrow of the world works death. Can’t you see the good fruit that has come, as God intended, because of your remorse over sin? Now you are eager to do what is right! Look at the indignation you experienced over what happened and how alarmed you became. What holy longing it awakened, what passion for God, and how ready you were to bring justice to the offender. Your response has proved that you are free of blame in this matter. So I wrote you not simply to correct the one who did the wrong or on the behalf of the one who was wronged, but to help you realize in God’s sight how loyal you are to us.
