Romans 13:8-10 set forth the obligation of a love which embraces all men, and comprehends all duties to them. The Apostle has just been laying down the general exhortation, Pay every man his due,' and applying it especially to the Christian's relation to civic rulers. He repeats it in a negative form, and bases on it the obligation of loving every man. That love is further represented as the sum and substance of the law. Thus Paul brings together two thoughts which are often dealt with as mutually exclusive,--namely, love and law. He does not talk sentimentalisms about the beauty of charity and the like, but lays it down, as a hard and fast rule,' that we are bound to love every man with whom we come in contact; or, as the Greek has it, the other.'
That is the first plain truth taught here. Love is not an emotion which we may indulge or not, as we please. It is not to select its objects according to our estimate of their lovableness or goodness. But we are bound to love, and that all round, without distinction of beautiful or ugly, good or bad. A hard saying; who can hear it?' Every man is our creditor for that debt. He does not get his due from us unless he gets love. Note, further, that the debt of love is never discharged. After all payments it still remains owing. There is no paying in full of all demands, and, as Bengel says, it is an undying debt. We are apt to weary of expending love, especially on unworthy recipients, and to think that we have wiped off all claims, and it may often be true that our obligations to others compel us to cease helping one; but if we laid Paul's words to heart, our patience would be longer-breathed, and we should not be so soon ready to shut hearts and purses against even unthankful suitors.
Further, Paul here teaches us that this debt (debitum, duty') of love includes all duties. It is the fulfilling of the law, inasmuch as it will secure the conduct which the law prescribes. The Mosaic law itself indicates this, since it recapitulates the various command-merits of the second table, in the one precept of love to our neighbour (Lev. 19:18). Law enjoins but has no power to get its injunctions executed. Love enables and inclines to do all that law prescribes, and to avoid all that it prohibits. The multiplicity of duties is melted into unity; and that unity, when it comes into act, unfolds into whatsoever things are lovely and of good report. Love is the mother tincture which, variously diluted and manipulated, yields all potent and fragrant draughts. It is the white light which the prism of daily life resolves into its component colours.
But Paul seems to limit the action of love here to negative doing no ill. That is simply because the commandments are mostly negative, and that they are is a sad token of the lovelessness natural to us all. But do we love ourselves only negatively, or are we satisfied with doing ourselves no harm? That stringent pattern of love to others not only prescribes degree, but manner. It teaches that true love to men is not weak indulgence, but must sometimes chastise, and thwart, and always must seek their good, and not merely their gratification.
Whoever will honestly seek to apply that negative precept of working no ill to others, will find it positive enough. We harm men when we fail to help them.
If we can do them a kindness, and do it not, we do them ill. Non-activity for good is activity for evil. Surely, nothing can be plainer than the bearing of this teaching on the Christian duty as to intoxicants. If by using these a Christian puts a stumbling-block in the way of a weak will, then he is working ill to his neighbour, and that argues absence of love, and that is dishonest, shirking payment of a plain debt.
