Ephesians 6:5-8

6:5 Slaves, obey your human masters with fear and trembling, in the sincerity of your heart as to Christ, 6:6 not like those who do their work only when someone is watching – as people-pleasers – but as slaves of Christ doing the will of God from the heart. 6:7 Obey with enthusiasm, as though serving the Lord and not people, 6:8 because you know that each person, whether slave or free, if he does something good, this will be rewarded by the Lord.
