Ephesians 6:5-9

5 Servants, be obedient to them that are your masters according to the flesh, with fear and trembling, in singleness of your heart, as to Christ;

6 Not with eye-service, as men pleasers; but as the servants of Christ, doing the will of God from the heart;

7 With good will doing service, as to the Lord, and not to men:

8 Knowing that whatever good thing any man does, the same shall he receive of the Lord, whether he be bond or free.

9 And, you masters, do the same things to them, forbearing threatening: knowing that your Master also is in heaven; neither is there respect of persons with him.
