'Approved' in the Bible

For 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.

For not he that commendeth himself is approved, but whom the Lord commendeth.

Now we pray to God that ye do no evil; not that we may appear approved, but that ye may do that which is honorable, though we be as reprobate.
