2 Corinthians 7:6-9

7:6 But God, who encourages the downhearted, encouraged us by the arrival of Titus. 7:7 We were encouraged not only by his arrival, but also by the encouragement you gave him, as he reported to us your longing, your mourning, your deep concern for me, so that I rejoiced more than ever. 7:8 For even if I made you sad by my letter, I do not regret having written it (even though I did regret it, for I see that my letter made you sad, though only for a short time). 7:9 Now I rejoice, not because you were made sad, but because you were made sad to the point of repentance. For you were made sad as God intended, so that you were not harmed in any way by us.
