Colossians 3:14, 23-25

and above all these things put on love, which is the bond of perfectness.

whatsoever ye do, work heartily, as unto the Lord, and not unto men; knowing that from the Lord ye shall receive the recompense of the inheritance: ye serve the Lord Christ. For he that doeth wrong shall receive again for the wrong that he hath done: and there is no respect of persons.
