Godly grief produces repentance that leads to salvation

Scripture reference

2 Corinthians 7:9–11 (ASV)

9I now rejoice, not that ye were made sorry, but that ye were made sorry unto repentance; for ye were made sorry after a godly sort, that ye might suffer loss by us in nothing. 10For godly sorrow worketh repentance unto salvation, a repentance which bringeth no regret: but the sorrow of the world worketh death. 11For 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.
