Ephesians 6:5-9 MSG

5 Servants, respectfully obey your earthly masters but always with an eye to obeying the real master, Christ.
6 Don't just do what you have to do to get by, but work heartily, as Christ's servants doing what God wants you to do.
7 And work with a smile on your face, always keeping in mind that no matter who happens to be giving the orders, you're really serving God.
8 Good work will get you good pay from the Master, regardless of whether you are slave or free.
9 Masters, it's the same with you. No abuse, please, and no threats. You and your servants are both under the same Master in heaven. He makes no distinction between you and them.
