2 Corinthians 7:8-9; 2 Corinthians 7:12-13
For even if I made you sorry with my letter, I do not regret it (though I did regret it, for I see that I grieved you with that letter, though only briefly).
Now I rejoice, not because you were grieved, but because your grief led to repentance; for you felt a godly grief, so that you were not harmed in any way by us.
So although I wrote to you, it was not on account of the one who did the wrong, nor on account of the one who was wronged, but in order that your zeal for us might be made known to you before God.
In this we find comfort. In addition to our own consolation, we rejoiced still more at the joy of Titus, because his mind has been set at rest by all of you.
