8 For though my letter gave you pain, I have no regret for it now, though I had before; for I see that the letter gave you pain, but only for a time.
9 Now I am glad, not that you had sorrow, but that your sorrow was the cause of a change of heart; for yours was a holy sorrow so that you might undergo no loss by us in anything.
10 For the sorrow which God gives is the cause of salvation through a change of heart, in which there is no reason for grief: but the sorrow of the world is a cause of death.
11 For you see what care was produced in you by this very sorrow of yours before God, what clearing of yourselves, what wrath against sin, what fear, what desire, what serious purpose, what punishment. In everything you have made it clear that you are free from sin in this business.
12 So though I sent you a letter, it was not only because of the man who did the wrong, or because of him to whom the wrong was done, but so that your true care for us might be made clear in the eyes of God.
