Ephesians 6:5-9

5Slaves, be obedient to those who are your earthly masters, with respect for authority, and with a sincere heart [seeking to please them], as [service] to Christ—

6not in the way of eye-service [working only when someone is watching you and only] to please men, but as slaves of Christ, doing the will of God from your heart;

7rendering service with goodwill, as to the Lord, and not [only] to men,

8knowing that whatever good thing each one does, he will receive this back from the Lord, whether [he is] slave or free.

9You masters, do the same [showing goodwill] toward them, and give up threatening and abusive words, knowing that [He who is] both their true Master and yours is in heaven, and that there is no partiality with Him [regardless of one’s earthly status].
