Slaves, obey your earthly masters in everything; and do it, not only when their eye is on you and to win their favor, but with sincerity of heart and reverence for the Lord. Whatever you do, work at it with all your heart, as working for the Lord, not for men, since you know that you will receive an inheritance from the Lord as a reward. It is the Lord Christ you are serving.
In our society today, we often have different outfits that we wear for work, at home, going out in public, etc. but the new clothes of a Christian are the same no matter where you are. In this passage, we see that this goes for our workplace as well as our home. When we realize that we work for Jesus and not for men, it can change our attitude and we will be the best workers that we can. Many will go to work and labor when someone is standing over them and watching but not work once they are not being monitored. As Christians, we know that God is always watching and knows all so we should be the same whether a supervisor is watching or not.
