Now I rejoice, not that you were made sorry, but that
your sorrow led to repentance. For you were made sorry in a godly manner,
that you might suffer loss from us in nothing. For godly sorrow produces repentance leading to
salvation, not to be regretted; but the sorrow of the world produces death. For observe this very thing, that you sorrowed in a godly manner: What
diligence it produced in you, what clearing of yourselves, what indignation, what
fear, what vehement desire, what zeal, what vindication! In all things you proved yourselves to be clear in this matter.
2 Corinthians 7:9-11
