'Godly Sorrow' in the Bible

Now I rejoice, not in your grief, but because the grief led to repentance; for you sorrowed with a godly sorrow, which prevented you from receiving injury from us in any respect.

For godly sorrow worketh repentance to salvation not to be repented of: but the sorrow of the world worketh 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.
