For the kind of sorrow God wants us to experience leads us away from sin and results in salvation. There’s no regret for that kind of sorrow. But worldly sorrow, which lacks repentance, results in spiritual death.
For the sorrow that is according to the will of God produces a repentance without regret, leading to salvation, but the sorrow of the world produces death.
Keep his statutes and his commandments, which I am commanding you today for your own well-being and that of your descendants after you, so that you may long remain in the land that the Lord your God is giving you for all time.
