Slaves, obey your earthly masters in everything you do. Try to please them all the time, not just when they are watching you. Serve them sincerely because of your reverent fear of the Lord.
Work willingly at whatever you do, as though you were working for the Lord rather than for people.
Remember that the Lord will give you an inheritance as your reward, and that the Master you are serving is Christ.
References for Colossians 3:24
But if you do what is wrong, you will be paid back for the wrong you have done. For God has no favorites.
