Ephesians 6:5-8

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