Romans VerseQuest Commentary Essay 89: Love Is the Fulfilling of the Law

Key Passage: Romans 13:8–10

Introduction

Romans 13:8–10 says, “Owe no man any thing, but to love one another: for he that loveth another hath fulfilled the law. For this, Thou shalt not commit adultery, Thou shalt not kill, Thou shalt not steal, Thou shalt not bear false witness, Thou shalt not covet; and if there be any other commandment, it is briefly comprehended in this saying, namely, Thou shalt love thy neighbour as thyself. Love worketh no ill to his neighbour: therefore love is the fulfilling of the law.” Paul has just dealt with the believer’s responsibilities in civil society: tribute, custom, fear, and honour are to be rendered where they are legitimately due. Now he moves from debts that can be paid to one debt that never disappears while we walk among other people. A tax can be paid. A bill can be settled. A loan can reach a zero balance. But the Christian never reaches the point where he can say, “I have loved that man enough; I owe him nothing more.” Love remains the continuing debt of grace.

This passage also demolishes two opposite errors that have troubled Christians for centuries: legalism and lawlessness. Legalism drags the believer back beneath the Mosaic law as though Christ had not finished the work of redemption and justification still waited on human performance. Lawlessness runs in the opposite direction and says that because the believer is under grace, moral conduct no longer matters. Paul shuts both doors. The Church Age believer is not justified by keeping the law, is not maintained in salvation by keeping the law, and is not placed back under Israel’s covenant at Sinai. Romans has already declared, “ye are not under the law, but under grace.” Yet the same apostle now quotes moral commandments and shows that love produces conduct consistent with their righteous purpose. Grace did not save the adulterer so he could commit adultery more comfortably. Grace did not justify the thief so he could steal with eternal security in his pocket. Grace saves the sinner and then teaches him how a redeemed man ought to walk.

The key is Paul’s statement, “Love worketh no ill to his neighbour.” Biblical love is not sentimental fog. It has moral content. It refuses adultery because adultery wrongs another. It refuses murder because murder destroys another. It refuses theft because theft takes what belongs to another. It refuses false witness because lying injures another. It refuses covetousness because coveting looks at another man’s blessings with a thief already forming in the heart. The law can identify those sins, forbid those sins, and pronounce them wrong, but the law cannot produce divine love in Adam’s fallen nature. Grace can. The Holy Ghost can. The new man can walk in it. Legalism can hang a sign saying, “Do not steal the fruit.” Grace changes the tree so different fruit grows. That is why love fulfills what legalism can command but never create.

1. Owe No Man Any Thing

Paul begins, “Owe no man any thing.” The immediate context has just said, “Render therefore to all their dues.” The believer is to be a man who takes obligations seriously. Christianity does not sanctify irresponsibility. If something is legitimately owed, the Christian should not treat payment as an optional spiritual exercise. He should not build a reputation for dodging obligations, breaking promises, leaving others to carry his responsibilities, and then cover the mess with religious vocabulary. A man may quote Romans all afternoon, but if everybody in town has to chase him to get what he promised them, his commentary is being contradicted by his checkbook.

The principle reaches beyond money into Christian integrity. The believer should not live as though other people exist to finance his appetites, absorb his irresponsibility, or clean up his unfinished business. Scripture repeatedly emphasizes honest dealing. Romans 12:17 has already commanded, “Provide things honest in the sight of all men.” Romans 13:7 said, “Render therefore to all their dues.” Paul is building a Christian life that is responsible before God and credible before men. Grace does not produce freeloaders. Grace teaches a man that his word matters, his obligations matter, and the testimony of Jesus Christ should not be dragged through the mud because he refuses to behave honestly.

This does not mean Scripture forbids every legitimate financial arrangement involving future payment. The emphasis is that the believer should not wrongfully withhold what is due or live carelessly under obligations he refuses to honor. The Bible repeatedly recognizes lending, borrowing, repayment, and debt as realities, while warning against bondage and dishonesty. Paul’s concern is righteous conduct. Do not make a lifestyle out of owing everybody while paying nobody. Do not enjoy the benefit and despise the obligation. The Christian should be the sort of man whose earthly accounts reflect the honesty of his heavenly profession. A saved soul with crooked dealings is a terrible advertisement for straight doctrine.

2. The Debt That Never Disappears

Paul adds the great exception: “but to love one another.” There is a debt the believer never finishes paying. Love remains due. You may have loved yesterday, but today still presents another obligation. You may have served someone last month, forgiven someone last year, helped a brother ten years ago, and sacrificed greatly for your family, but none of that produces a certificate announcing that your account with Christian charity has permanently closed. Love does not accumulate retirement credits. As long as there is a neighbour before you, there remains an opportunity and obligation to walk in love.

This is because Christian love flows from what God has already done for the believer. Romans 5:8 says, “But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us.” First John 4:19 says, “We love him, because he first loved us.” The believer is not generating love out of Adam’s natural goodness, because Adam does not have enough natural goodness to fill a thimble once Scripture has finished examining him. The Christian loves because he has become the recipient of divine mercy. He has been forgiven, justified, reconciled, accepted, indwelt, and secured in Christ. Grace fills the reservoir before it tells the believer to pour.

The debt of love therefore cannot be reduced to pleasant feelings. Sometimes love feels warm; sometimes love requires doing right when feelings are dragging their feet fifty yards behind obedience. Love tells the truth. Love forgives. Love gives. Love refuses to defraud. Love exercises patience. Love warns when warning is necessary. Love serves when service is inconvenient. Love can say no to sin because biblical love is not afraid of being misunderstood by people who define love as unconditional approval. The Christian debt is not to make everybody happy. It is to treat others according to the love and righteousness of God. That debt remains until the believer leaves this present world.

3. He That Loveth Another Hath Fulfilled the Law

Paul says, “for he that loveth another hath fulfilled the law.” That statement must be read in its doctrinal setting or somebody will immediately drag the Christian back to Sinai and start rebuilding a covenant God never made with the Church. Romans 6:14 says plainly, “for ye are not under the law, but under grace.” Romans 7 explains the believer’s deliverance from the law in relation to righteousness and fruit-bearing. Romans 10:4 says, “For Christ is the end of the law for righteousness to every one that believeth.” Paul is not reversing eleven chapters of doctrine in one sentence. He is showing what grace-produced love accomplishes toward another person.

To fulfill the law here is not to obtain justification by performing the Mosaic code. It is to produce the righteous treatment of one’s neighbour that the moral commandments demanded. The law says, “Thou shalt not steal.” Love says, “I will not take what belongs to my neighbour because I seek his good.” The law says, “Thou shalt not bear false witness.” Love says, “I will not destroy my neighbour with lies.” The law says, “Thou shalt not commit adultery.” Love says, “I will not violate another person’s marriage, body, home, or trust.” The external command and the inward motive meet in righteous conduct, but the source is entirely different.

That distinction is where legalism loses its teeth. The law can command a man not to steal, but it cannot make a thief generous. It can command him not to kill, but it cannot make him love his enemy. It can condemn covetousness, but it cannot make him rejoice when another man is blessed. The law is holy, just, and good, but fallen flesh is the problem. Romans 8:3 speaks of “what the law could not do, in that it was weak through the flesh.” Grace deals with the sinner through Christ, gives him the Spirit, renews the mind, and produces something external regulation never could. Sinai can post the speed limit. It cannot install a new engine.

4. Thou Shalt Not Commit Adultery, Kill, or Steal

Paul begins naming commandments: “Thou shalt not commit adultery, Thou shalt not kill, Thou shalt not steal.” Notice that grace has not suddenly decided adultery, murder, and theft are harmless because the believer is no longer under the Mosaic covenant. That ought to be obvious, but sin has a remarkable ability to become stupid when it wants permission. Paul is writing directly to Church Age believers and uses these commandments to demonstrate the moral shape of love. Love does not injure another person through sexual betrayal, violence, or theft. Grace does not erase morality; it produces righteousness on a better foundation.

Adultery violates love because it takes what God has joined and introduces treachery into the covenant of marriage. It wrongs spouses, families, children, consciences, and bodies. The world may rename adultery an affair, indiscretion, personal journey, or complicated relationship, but a softer label does not make the knife less sharp. Biblical love refuses to use another human being as an instrument of lust. First Corinthians 13:5 says charity “seeketh not her own.” Adultery is lust seeking its own at somebody else’s expense. It is selfishness dressed for romance, and Scripture is not impressed by the wardrobe.

Murder and theft likewise work ill toward the neighbour. Murder attacks his life; theft attacks what rightly belongs to him. The principles extend beyond the final outward acts. Hatred, cruelty, fraud, cheating, exploitation, and deliberate injury all contradict the love Paul is describing. A Christian cannot sing about loving Jesus while deliberately cheating his neighbour and expect heaven to applaud the harmony. Grace brings conduct into the light. Love respects life. Love respects another man’s marriage. Love respects another man’s property. A gospel that leaves a man comfortable in the deliberate destruction of his neighbour has not been understood, no matter how loudly he says “grace.”

5. False Witness and Covetousness

Paul continues, “Thou shalt not bear false witness, Thou shalt not covet.” False witness concerns the tongue, testimony, reputation, and truth. A lie can injure another person without touching his body or property. It can destroy trust, damage reputation, divide friendships, poison churches, ruin businesses, and turn families against one another. The tongue is small enough to hide behind the teeth and powerful enough to burn down a life. James calls it “a fire, a world of iniquity.” Love therefore refuses to weaponize falsehood against the neighbour.

False witness also includes the half-truth, selective retelling, malicious exaggeration, and convenient omission designed to make another person look worse than the facts warrant. Religious people can become masters of this because gossip sounds more respectable when introduced with, “We really need to pray for him.” By the time the prayer request reaches the sixth person, the fellow needs a lawyer more than an intercessor. Love without dissimulation refuses that game. It tells the truth because truth belongs to God and the neighbour’s reputation is not a chew toy for the tongue.

Covetousness goes even deeper because it exposes the heart before the hand commits the outward offense. “Thou shalt not covet” deals with desire. A man can avoid adultery outwardly while coveting another man’s wife. He can avoid theft while coveting another man’s possessions. He can never murder anyone while resenting another man’s success enough to wish him ruined. Covetousness is the thief still sitting in the planning room. Love shuts down the meeting. It learns contentment, rejoices in another person’s good, and refuses to make another man’s blessing an accusation against God. Grace reaches where the policeman cannot—the desires behind the locked door of the heart.

6. Thou Shalt Love Thy Neighbour as Thyself

Paul says, “and if there be any other commandment, it is briefly comprehended in this saying, namely, Thou shalt love thy neighbour as thyself.” The commandments governing conduct toward others are gathered into this principle. “Briefly comprehended” does not mean abolished, trivialized, or emptied of moral content. It means summarized. Love is the governing principle that produces the kind of conduct those commandments require. A man who genuinely loves his neighbour will not need somebody standing beside him every hour reminding him not to rob, murder, defraud, slander, or seduce him. Love has already closed those doors from the inside.

“Thy neighbour” also prevents Christian love from becoming a private club reserved for people who are easy to like. The neighbour is another human being placed within the sphere of our conduct and responsibility. The Lord Jesus made that painfully clear when He told of the Samaritan who helped the wounded man while religious men passed by. Love asks what good can be done, not whether the person belongs to the right social circle, denomination, class, nationality, or personality type. The flesh loves selective charity because selective charity is cheaper. Biblical love keeps walking until it finds the wounded man.

“As thyself” assumes the ordinary human instinct of self-preservation and uses it as the measure of practical concern. Men naturally feed themselves, protect themselves, seek shelter, defend their interests, and attend to their own needs. Paul says turn that practical concern outward. Consider what your actions do to the other man. Would you want your marriage violated? Your property stolen? Your reputation lied about? Your success resented? Your body harmed? Your need ignored? Then do not work that ill toward another. Love takes self out of the center without pretending self does not exist. It teaches the believer to see his neighbour as somebody whose welfare matters before God.

Conclusion

Romans 13:8–10 leaves the believer with a debt that can never be stamped PAID IN FULL during this earthly walk: “Owe no man any thing, but to love one another.” Paul has just told the Christian to render tribute, custom, fear, and honour where they are due; now he moves beyond debts that can be settled to the continuing obligation of love. The believer does not love his neighbour in order to be justified, stay justified, or earn eternal life. Romans settled justification long before Paul reached chapter 13. We are “justified freely by his grace through the redemption that is in Christ Jesus,” and “being justified by faith, we have peace with God through our Lord Jesus Christ.” Love is therefore not the price of salvation but the fruit of salvation working itself out toward other people. Grace does not leave a man morally bankrupt after paying his eternal debt. It creates in him a new obligation—not to earn God’s favor, but to treat his neighbour according to the righteousness of the God who has already shown him mercy.

That is why Paul can name the commandments against adultery, killing, stealing, false witness, and coveting and then say, “if there be any other commandment, it is briefly comprehended in this saying, namely, Thou shalt love thy neighbour as thyself.” Grace has not made adultery acceptable, murder harmless, theft Christian liberty, lying a personality trait, or covetousness a respectable ambition. The believer is not under the Mosaic law as Israel was under that covenant, and he certainly is not keeping commandments to establish his own righteousness before God. But neither has grace turned holiness into an antique from Sinai. The righteousness toward one’s neighbour that the law commanded is produced in the believer through love. Legalism can stand over a man with a list and say, “Do not steal from him.” Grace goes deeper and teaches him to love the man enough that he does not want to steal from him. The law can identify the crooked branch; grace changes what kind of fruit grows on the tree. Legalism can demand righteousness from the flesh, but it cannot manufacture the love that fulfills it.

Paul therefore closes the argument with a sentence simple enough for a child to understand and deep enough to expose a lifetime of religious pretense: “Love worketh no ill to his neighbour: therefore love is the fulfilling of the law.” Biblical love does not injure the neighbour and then hide behind grace. It does not commit adultery against him, steal from him, lie about him, covet what belongs to him, destroy him with the tongue, cheat him in business, or excuse selfishness with spiritual vocabulary. Love seeks his good because love has learned its character from the Lord Jesus Christ. That is the difference between lawlessness and grace, and between legalism and genuine Christian living. Lawlessness says, “I am free, therefore I may please myself.” Legalism says, “I must perform so God will accept me.” Grace says, “God has accepted me in Christ; therefore I am free to serve Him and love my neighbour.” The law can point at the standard. Grace produces the life that walks in it. Love worketh no ill to his neighbour, and that is why love is the fulfilling of the law.
