8 Owe no one anything except to love one another, for he who loves another has fulfilled the law. 9 For the commandments, "You shall not commit adultery," "You shall not murder," "You shall not steal," "You shall not bear false witness," "You shall not covet," and if there is any other commandment, are all summed up in this saying, namely, "You shall love your neighbor as yourself."
Matthew Henry's Commentary on Romans 13:8-9
Commentary on Romans 13:8-10
(Read Romans 13:8-10)
Christians must avoid useless expense, and be careful not to contract any debts they have not the power to discharge. They are also to stand aloof from all venturesome speculations and rash engagements, and whatever may expose them to the danger of not rendering to all their due. Do not keep in any one's debt. Give every one his own. Do not spend that on yourselves, which you owe to others. But many who are very sensible of the trouble, think little of the sin, of being in debt. Love to others includes all the duties of the second table. The last five of the ten commandments are all summed up in this royal law, Thou shalt love thy neighbour as thyself; with the same sincerity that thou lovest thyself, though not in the same measure and degree. He that loves his neighbour as himself, will desire the welfare of his neighbour. On this is built that golden rule, of doing as we would be done by. Love is a living, active principle of obedience to the whole law. Let us not only avoid injuries to the persons, connexions, property, and characters of men; but do no kind or degree of evil to any man, and study to be useful in every station of life.
