Eph 6:5-8

Slaves and Masters 5Slaves, obey your earthly masters with fear and trembling, in singleness of heart, as you obey Christ;6not only while being watched, and in order to please them, but as slaves of Christ, doing the will of God from the heart.7Render service with enthusiasm, as to the Lord and not to men and women,8knowing that whatever good we do, we will receive the same again from the Lord, whether we are slaves or free.
