2 Corinthians 7:10-13

For [godly] sorrow that is in accord with the will of God produces a repentance without regret, leading to salvation; but worldly sorrow [the hopeless sorrow of those who do not believe] produces death. For [you can look back and] see what an earnestness and authentic concern this godly sorrow has produced in you: what vindication of yourselves [against charges that you tolerate sin], what indignation [at sin], what fear [of offending God], what longing [for righteousness and justice], what passion [to do what is right], what readiness to punish [those who sin and those who tolerate sin]! At every point you have proved yourselves to be innocent in the matter. So even though I wrote to you [as I did], it was not for the sake of the offender nor for the sake of the one offended, but in order to make evident to you before God how earnestly you do care for us [and your willingness to accept our authority]. It is for this reason that we are comforted and encouraged. A nd in addition to our comfort, we were especially delighted at the joy of Titus, because you have refreshed his spirit.
