2 Corinthians 7:7; 2 Corinthians 7:11

7 and not only by his coming, but also by the comfort with which he was comforted in you, as he reported to us your longing, your mourning, your zeal for me; so that I rejoiced even more.

11 For behold what earnestness this very thing, this godly sorrow, has produced in you: what vindication of yourselves, what indignation, what fear, what longing, what zeal, what avenging of wrong! In everything you demonstrated yourselves to be innocent in the matter.
