"Whatever you do, work heartily, as for the Lord and not for men."
Whatever your task may be, work from the soul. Put in your very best effort. It is something done for the Lord, not for your earthly masters. God has put you there, so put every effort as if you are working for Him.
Do your best. Work from the heart for your real Master, for God. Be confident that you’ll get paid in full when you come into your inheritance. Keep in mind always that the ultimate Master you’re serving is Christ.
