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.
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.
Or do you not know that your body is a temple of the Holy Spirit within you, whom you have from God, and that you are not your own? For you have been bought for a price: therefore glorify God in your body.
