2 Corinthians 7:7-11

We were comforted, not only by his coming but also by the comfort you gave him. Titus told us about your wish to see me and that you are very sorry for what you did. He also told me about your great care for me, and when I heard this, I was much happier. Even if my letter made you sad, I am not sorry I wrote it. At first I was sorry, because it made you sad, but you were sad only for a short time. Now I am happy, not because you were made sad, but because your sorrow made you change your lives. You became sad in the way God wanted you to, so you were not hurt by us in any way. The kind of sorrow God wants makes people change their hearts and lives. This leads to salvation, and you cannot be sorry for that. But the kind of sorrow the world has brings death. See what this sorrow—the sorrow God wanted you to have—has done to you: It has made you very serious. It made you want to restore yourselves. It made you angry and afraid. It made you want to see me. It made you care. It made you want to do the right thing. In every way you have regained your innocence.
