``Slaves, obey your earthly masters with deep respect and fear. Serve them sincerely as you would serve Christ. Work hard, but not just to please your masters when they are watching. As slaves of Christ, do the will of God with all your heart. Work with enthusiasm, as though you were working for the Lord rather than for people. Remember that the Lord will reward each one of us for the good we do, whether we are slaves or free.``
