2 Corinthians 7:8-10

For though I made you sorry with my epistle, I do not regret it: though I did regret it (for I see that that epistle made you sorry, though but for a season), I now rejoice, not that ye were made sorry, but that ye were made sorry unto repentance; for ye were made sorry after a godly sort, that ye might suffer loss by us in nothing. For godly sorrow worketh repentance unto salvation, a repentance which bringeth no regret: but the sorrow of the world worketh death.
