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
'Therefore,' he says, 'though I did regret before I saw the fruit and the gain, how great they were I do not regret now .' For such a thing is godly sorrow. And then he philosophizes about it, showing that sorrow is not in all cases a grievous thing, but when it is worldly. And what is worldly? If you be in sorrow for money, for reputation, for him that is departed, all these are worldly. Wherefore also they work death. For he that is in sorrow for reputation's sake feels envy and is driven oftentimes to perish: such sorrow was that which Cain sorrowed, such Esau. By this worldly sorrow then he means that which is to the harm of those that sorrow. For only in respect to sins is sorrow a profitable thing; as is evident in this way. He that sorrowes for loss of wealth repairs not that damage; he that sorrowes for one deceased raises not the dead to life again; he that sorrowes for a sickness, not only is not made well but even aggravates the disease: he that sorrowes for sins, he alone attains some advantage from his sorrow, for he makes his sins wane and disappear. For since the medicine has been prepared for this thing, in this case only is it potent and displays its profitableness; and in the other cases is even injurious. 'And yet Cain,' says one, 'sorrowed because he was not accepted with God.' It was not for this, but because he saw his brother glorious in honor ; for had he grieved for this, it behooved him to emulate and rejoice with him; but, as it was, grieving, he showed that his was a worldly sorrow. But not so did David, nor Peter, nor any of the righteous. Wherefore they were accepted, when grieving either over their own sins or those of others. And yet what is more oppressive than sorrow? Still when it is after a godly sort, it is better than the joy in the world. For this indeed ends in nothing; but that works repentance unto salvation, a salvation that brings no regret. For what is admirable in it is this that one who had thus sorrowed would never repent, while this is a special characteristic of worldly sorrow. For what is more regretted than a true born son? And what is a heavier grief than a death of this sort? But yet those fathers who in the height of their grief endure nobody and who wildly beat themselves, after a time repent because they have grieved immoderately; as having thereby nothing benefitted themselves, but even added to their affliction. But not such as this is godly sorrow; but it possesses two advantages, that of not being condemned in that a man grieves for, and that this sorrow ends in salvation; of both which that is deprived. For they both sorrow unto harm and after they have sorrowed vehemently condemn themselves, bringing forth this greatest token of having done it unto harm. But godly sorrow is the reverse [of this]: wherefore also he said, works repentance unto salvation, a repentance that brings no regret. For no one will condemn himself if he have sorrowed for sin, if he have mourned and afflicted himself. Which also when the blessed Paul has said he needs not to adduce from other sources the proof of what he said, nor to bring forward those in the old histories who sorrowed, but he adduces the Corinthians themselves; and furnishes his proof from what they had done; that along with praises he might both instruct them and the rather win them to himself.
