2 Corinthians 7:10-13

For godly sorrow worketh repentance unto salvation, a repentance which bringeth no regret: but the sorrow of the world worketh death. For behold, this selfsame thing, that ye were made sorry after a godly sort, what earnest care it wrought in you, yea what clearing of yourselves, yea what indignation, yea what fear, yea what longing, yea what zeal, yea what avenging! In everything ye approved yourselves to be pure in the matter. So although I wrote unto you, I wrote not for his cause that did the wrong, nor for his cause that suffered the wrong, but that your earnest care for us might be made manifest unto you in the sight of God. Therefore we have been comforted: and in our comfort we joyed the more exceedingly for the joy of Titus, because his spirit hath been refreshed by you all.
