2 Corinthians 7:8-10

Even if my letter made you sorrowful, I don’t regret sending it (even though I felt awful for a moment when I heard how it grieved you). Now I’m overjoyed—not because I made you sad, but because your grief led you to a deep repentance. You experienced godly sorrow, and as God intended, it brought about gain for you, not loss, so that no harm has been done by us. God designed us to feel remorse over sin in order to produce repentance that leads to victory. This leaves us with no regrets. But the sorrow of the world works death.
