2 Corinthians 7:7-10

7and not only by his coming, but also by the encouragement with which he was encouraged by you, as he told us of your longing, your mourning, and your deep concern for me—so that I rejoiced still more.

8For even if I grieved you with my letter, I do not regret it—though I did regret it, for I see that my letter grieved you, but just for a while.

9Now I rejoice, not that you were grieved, but that you were grieved to the point of repentance. For you were grieved according to God’s will, so that you might in no way suffer loss from us.

10For the grief that God wills brings a repentance that leads to salvation, leaving no regret. But the world’s grief brings death.
