Ephesians 6:5-8

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