The Apostle Paul writing to the Corinthians:
For though I caused you sorrow by my letter, I do not regret it; though I did regret it—for I see that that letter caused you sorrow, though only for a while – I now rejoice, not that you were made sorrowful, but that you were made sorrowful to the point of repentance; for you were made sorrowful according to the will of God, so that you might not suffer loss in anything through us.
For the sorrow* that is according to the will of God produces a repentance without regret, leading to salvation, but the sorrow* of the world produces death. For behold what earnestness this very thing, this godly sorrow*, has produced in you: what vindication of yourselves, what indignation, what fear, what longing, what zeal, what avenging of wrong! In everything you demonstrated yourselves to be innocent in the matter.
II Corinthians 7:8-11
*Sorrow – grief, pain, heaviness of mind.
