2 Corinthians 7:9-11

9Now I rejoice, not that ye have been grieved, but that ye have been grieved to repentance; for ye have been grieved according to 1God, that in nothing ye might be injured by us.

10For grief according to 2God works repentance to salvation, never to be regretted; but the grief of the world works death.

11For, behold, this same thing, your being grieved according to 3God, how much diligence it wrought in you, but [what] excusing [of yourselves], but [what] indignation, but [what] fear, but [what] ardent desire, but [what] zeal, but [what] vengeance: in every way ye have proved yourselves to be pure in the matter.
