Ephesians 6:5-8

Slaves, obey your human masters with fear and trembling, in the sincerity of your heart, as to Christ. Don’t work only while being watched, in order to please men, but as slaves of Christ, do God’s will from your heart. Serve with a good attitude, as to the Lord and not to men, knowing that whatever good each one does, slave or free, he will receive this back from the Lord.
