2 Corinthians 7:7-10

7And not by his coming only, but by the consolation with which he was comforted in you, when he told us your earnest desire, your mourning, your fervent mind toward me; so that I rejoiced the more. 8For though I made you sorry with a letter, I do not repent, though I did repent: for I perceive that the same epistle hath made you sorry, though it was but for a season. 9Now I rejoice, not that ye were made sorry, but that ye sorrowed to repentance: for ye were made sorry after a godly manner, that ye might suffer loss through us in nothing.1 10For godly sorrow worketh repentance to salvation not to be repented of: but the sorrow of the world worketh death.
