Colossians 3:22-24

22Servants, obey in all things them that are your masters according to the flesh; not with eye-service, as men-pleasers, but in singleness of heart, fearing the Lord: 23whatsoever ye do, work heartily, as unto the Lord, and not unto men; 24knowing that from the Lord ye shall receive the recompense of the inheritance: ye serve the Lord Christ.
