Letter to the Ephesians

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

not in the way of service only when eyes are on you, as men-pleasers; but as servants of Christ, doing the will of God from the heart;

with good will doing service, as to the Lord, and not to men;

knowing that whatever good thing each one does, he will receive the same again from the Lord, whether he is bound or free.
