For godly sorrow works repentance to salvation not to be regretted: but the sorrow of the world works death.
All Commentaries on 2 Corinthians 7:10 Go To 2 Corinthians 7
John Chrysostom
AD 407
However, I marvel how God, who from the beginning gave humanity pain, which came from sin, abolishes his decision with one resolution and expels the judgment with the sentence. And hear how. Sin produced pain, and through pain sin is annihilated. Pay attention carefully. God threatens the woman. He brings upon her the punishment for her disobedience, and he tells her: “You shall bring forth children in pain.” And he showed pain as the harvest of sin. However, oh, how munificent he is! That which he gave for punishment he changed to salvation. Sin gave birth to pain; pain destroys sin. Just as a worm that is born by a tree consumes the very same tree, likewise pain, which is born by sin, kills sin when it is supplied by repentance. For this reason Paul says: “Godly pain produces a repentance that leads to salvation and brings no regret.” Pain is good for those who repent sincerely; the sorrow, matching the sin, suits those who sin… . Mourn for the sin so you may not lament for the punishment. Apologize to the judge before you come to the court. Or do you not know that all who want to sin flatter the judge, not when the case is being tried but before they enter the court, or through friends, or through guardians, or through another way they coax the judge? The same with God: you cannot persuade the Judge during the time of the tribunal. It is possible for you to plead with the Judge before the time of judgment. .
