Ephesians 6:7

slaving with good-will from your heart, as for the Lord and not for men;

Because whether you are eating or whether you are drinking, you are to do it all for the glory of God.

Slaves, be obedient to those who are your earthly masters, with reverence and humility, in singleness of heart as if to Christ himself;

And whatever you do, do it heartily as for the Lord, and not for men.
