Ephesians 6:
5 Servants, be obedient to them that are your masters according to the flesh, with fear and trembling, in singleness of your heart, as unto Christ;
6 Not with eyeservice, as menpleasers; 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 whatsoever good thing any man doeth, the same shall he receive of the Lord, whether he be bond or free.
9 And, ye masters, do the same things unto them, forbearing threatening: knowing that your Master also is in heaven; neither is there respect of persons with him.
Eph.6:5-9
