Ephesians 6:1

Children, obey your parents in the Lord
The persons whose duty this is, "children", are such of every sex, male and female, and of every age, and of every state and condition; and though the true, legitimate, and immediate offspring of men may be chiefly respected, yet not exclusive of spurious children, and adopted ones, and of children-in-law; and the persons to whom obedience from them is due, are not only real and immediate parents, both father and mother, but such who are in the room of parents, as step-fathers, step-mothers, guardians, nurses and all who are in the ascending line, as grandfathers, grandmothers to these, children should be subject and obedient in all things lawful, just, and good; in everything that is not sinful and unlawful, by the word of God; and in things indifferent, as much as in them lies, and even in things which are difficult to perform: and this obedience should be hearty and sincere, and not merely verbal, and in show and appearance, nor mercenary; and should be joined with gratitude and thankfulness for past favours: and it should be "in the Lord"; which may be considered either as a limitation of the obedience, that it should be in things that are agreeable to the mind and will of the Lord; or as an argument to it, because it is the command of the Lord, and is wellpleasing in his sight, and makes for his glory, and therefore should be done for his sake:

for this is right;
it appears to be right by the light of nature, by which the very Heathens have taught it; and it is equitable from reason that so it should be; and it is just by the law of God, which commands nothing but what is holy, just, and good.
