2 Corinthians 7:11-12

7:11 For see what this very thing, this sadness as God intended, has produced in you: what eagerness, what defense of yourselves, what indignation, what alarm, what longing, what deep concern, what punishment! In everything you have proved yourselves to be innocent in this matter. 7:12 So then, even though I wrote to you, it was not on account of the one who did wrong, or on account of the one who was wronged, but to reveal to you your eagerness on our behalf before God.
