2 Corinthians 7:9-11

9So now I am happy, but not because my letter made you sad. No, I am happy because it made you turn away from wrong things. You became sad as God wanted you to be sad. So, when the letter made you sad, we did not really hurt you.

10People need to become sad in the way that God wants. When they are sad like that, it causes them to turn away from wrong things. Then God saves them from their sins. They will never be sorry about that! But when people become sad in the way that the world wants, it does not help them. They do not turn to God and they die in their spirits.

11You became sad in the way that God wanted. And see what good results that has brought! It has made you work hard to do good things. You want to show people that you do what is right. You are angry against sin. You want to obey God. You want to make things right again. You want to please God. You want to punish anyone who does wrong things. In all these ways, you have shown that you are right. You have done everything that was necessary in this matter.
