Colossians 3:22 - 3:24
22 Slaves, in all things obey those who are your masters according to the flesh, not with eyeservice, as men-pleasers, but with integrity of heart, fearing the Lord. 23 Whatever you do, do your work heartily, as for the Lord rather than for men, 24 knowing that from the Lord you will receive the reward of the inheritance. Serve the Lord Christ.
