But we know that the law is good, if a man use it lawfully:

“"But we know that the law is good, if a man use it lawfully. Knowing this, that the law is not made for a righteous man." The law, he seems to say, is good, and again, not good. What then? if one use it not lawfully, is it not good? Nay even so it is good. But what he means is this; if any one fulfills it in his actions; for that is to "use it lawfully" as here intended. But when they expound it in their words, and neglect it in their deeds, that is using it unlawfully. For such an one uses it, but not to his own profit. And another way may be named besides. What is it? that the law, if thou use it aright, sends thee to Christ. For since its aim is to justify man, and it fails to effect this, it remits us to Him who can do so. Another way again of using the law lawfully, is when we keep it, but as a thing superfluous. And how as a thing superfluous? As the bridle is properly used, not by the prancing horse that champs it, but by that which wears it only for the sake of appearance, so he uses the law lawfully, who governs himself, though not as constrained by the letter of it. He uses the law lawfully who is conscious that he does not need it, for he who is already so virtuous that he fulfills it not from fear of it, but from a principle of virtue, uses it lawfully and safely: that is, if one so use it, not as being in fear of it, but having before his eyes rather the condemnation of conscience than the punishment hereafter. Moreover he calls him a righteous man, who has attained unto virtue. He therefore uses the law lawfully, who does not require to be instructed by it. For as points in reading are set before children; but he who does what they direct, without their aid, from other knowledge, shows more skill, and is a better reader; so he who is above the law, is not under the schooling of the law. For he keeps it in a much higher degree, who fulfills it not from fear, but from a virtuous inclination; since he that fears punishment does not fulfill it in the same manner as he that aims at reward. He that is under the law doth it not as he that is above the law. For to live above the law is to use it lawfully. He uses it lawfully, and keeps it, who achieves things beyond the law, and who does not need its instructions. For the law, for the most part, is prohibition of evil; now this alone does not make a man righteous, but the performance of good actions besides. Hence those, who abstain from evil like slaves, do not come up to the mark of the law. For it was appointed for the punishment of transgression. Such men indeed use it, but it is to dread its punishment. It is said, "Wilt thou not be afraid of the power? do that which is good" (Rom. xiii. 3): which implies, that the law threatens punishment only to the wicked. But of what use is the law to him whose actions deserve a crown? as the surgeon is of use only to him who hath some hurt, and not to the sound and healthy man.”

“Accordingly "the law is holy and the commandment holy, just and good." It commands what ought to be commanded, and prohibits what ought to be prohibited. "Was that which is good, then, made death to me? God forbid." The fault lies in making a bad use of the commandment, which in itself is good. "The law is good if one uses it lawfully." But he makes a bad use of the law who does not subject himself to God in humble piety, so that, with the aid of grace, he may become able to fulfill the law. He who does not use the law lawfully receives it to no other end than that his sin, which was latent before the prohibition, should be made apparent by his transgression.”

“Above he showed the dignity and usefulness of the virtues; here he declares the necessity of these, because whoever departs from these falls into the danger of false doctrine. And concerning this he does two things: first, the falsity of the doctrine into which they fall is set forth; second, the condition of those who teach falsely, at the words wishing to be. He says therefore: the end of the commandment, etc., and these are the chief things of the law, from which certain persons depart. Ps. 11:2: they have spoken vain things, etc. And note that departure from charity is the cause of false doctrine, because those who do not love charity fall into falsehood. 2 Thess. 2:11: who did not believe the truth, but consented to iniquity. Likewise those who let go of purity of heart. For those having a heart infected with the passions judge according to the affection of these, and not according to God. 1 Cor. 2:14: the animal man does not perceive the things that are of God, etc. Likewise those having an evil conscience, because they cannot rest in the truth. And hence it is that they seek false things, that they may rest in them. Below, in the same place: having faith and a good conscience. Likewise he who has a feigned trust. Is. 21:2: he who is unbelieving acts unfaithfully. Then, when he says wishing, etc., the condition of those teaching falsely is set forth, and first their disordered ambition; second their defect. As to the first he says wishing to be, etc. Matt. 23:6: they love the first places at feasts, and to be called by men, Rabbi, etc. James 3:1: be not many masters, etc. As to the second he says understanding neither. Ps. 81:5: they have not known, neither have they understood; they walk on in darkness. Wis. 5:6: the sun of understanding has not risen upon us. Nor the things which they speak by authorities, which they do not understand, nor the things about which they affirm, namely, by way of concluding. Then, when he says but we know, etc., he sets forth the condition of the law as to two things. First, as to the goodness of the law; second, as to the end and intention of the lawgiver, at the words knowing. He says therefore we know, namely with certainty, that the law is good, not evil, as the heretics say. Ps. 18:7: the law of the Lord is unspotted, etc. Rom. 7:12: the law indeed is holy, and the commandment holy, and just, and good. But it happens that someone uses a good thing badly. Since therefore the law is good, it is required that man use it well. And therefore he says if a man use it rightly. Otherwise death comes to him from it, as is said in Rom. 8. For in the law there are certain moral precepts, and certain ceremonial ones. The ceremonial ones indeed were given as a figure of Christ and the Church, but they need to be understood not only carnally, but also spiritually; and as a figure of things to come, and so that you may know that they are not to be kept forever, but cease when the truth comes. Jer. 31:31: and I will strike with the house of Israel and the house of Judah a new covenant, not according to the covenant which I made with your fathers, etc. And thus the Gloss expounds it. But the Apostle seems to be speaking of the moral precepts, because he adds that the law was made because of sins, and these are the moral precepts. The lawful use of these is that man not attribute to them more than what is contained in them. The law was given so that sin might be known. Rom. 7:7: for unless the law had said, you shall not covet, I would not have known concupiscence, etc.; which is said in the Decalogue. There is not, therefore, in them hope of justification, but in faith alone. Rom. 3:28: we reckon a man to be justified by faith without the works of the law. Then, when he says knowing, he shows the condition of the law as to the intention of the lawgiver; and first he sets forth the supposed intention; second he sets forth the true intention, at the words but for the unjust. The supposed intention is excluded, when he says for the just, etc. Here there could be a twofold false understanding. One, that the just man does not keep the law, which is false, because unless he kept it as to the moral precepts, he would not be just. Hence Christ too was made under the law. The other, that the just man is not bound to the precepts of the law, and would not sin if he acted against them. But the following sense is true, supposing that what is imposed on someone is imposed as a burden; for the law is not imposed on the just as a burden, because their interior habit inclines them to that to which the law inclines, and therefore it is not a burden to them. Rom. 2:14: they are a law to themselves. Or otherwise: the law was not made for the just, but for the unjust; as if to say: if all were just, there would be no need of giving a law, because all would be a law to themselves. The intention of good men ought to be that they lead others to the virtues. Now some are of themselves well disposed to the virtues; others have a mind well disposed, but through another, and for these a fatherly admonition suffices, not a coercive one; others, however, are well disposed neither of themselves nor through another; therefore for them a law is altogether necessary, as is clear in the Ethics. Then, when he says but for the unjust, etc., he sets forth the true intention; and first he describes in general those for whom the law is necessary; second in particular, at the words for murderers of fathers. Now it should be known that, as is said in 1 John 3:4, all sin is iniquity, and therefore it is opposed to some right. But since right is twofold, namely natural and positive, to the natural is opposed what is evil in itself, and to the positive is opposed what is evil because forbidden. As to the first he says but for the unjust, namely those who act against natural right. Is. 24:5: they have transgressed the laws, changed the right, broken the everlasting covenant, etc. As to the second he says not subject, namely to human precept. Rom. 1:30: disobedient to parents. And these two regard the notion of sin. He then sets forth others, which are taken by comparison to that, and this is either against God, or against one's neighbor, or in oneself. Against God it is called impiety, because piety implies the worship of God; therefore he says for the ungodly. Against one's neighbor, thus he says for sinners. Ps. 1:5: the wicked shall not rise again in judgment, etc. Gal. 2:15: we by nature are Jews, and not sinners of the Gentiles. But according to Augustine, in On Christian Doctrine, sins are distinguished into two, namely spiritual ones, which are called crimes, and carnal ones, and these are called shameful deeds; and therefore he says for the wicked, as to the spiritual. Prov. 17:9: he who hides crimes, etc. As to the carnal he says for the defiled. Mal. 2:11: Judah has profaned the sanctification of the Lord, etc. Then he enumerates the sins in particular. And first he names certain ones in particular; second he gathers the rest in general, at the words and if there be any other. First he sets forth sins of deed; second sins of the mouth, at the words for liars, etc. Concerning the first he sets forth, first, as to crimes; second, as to shameful deeds. Crimes are said to be those which are to the harm of one's neighbor. And the more closely joined the neighbor is, the graver their sin is, because we are more bound to them. And therefore he speaks first of the father, second of the mother. Ex. 20:12: honor your father and your mother, etc., and afterward 21:15: he who strikes his father or mother shall die the death; then he continues concerning other killings of neighbors, saying; Ex. 21:14: if anyone kill his neighbor by design, etc. Then he sets forth the shameful deeds, and first those which are according to nature, when he says for fornicators. Heb., last chapter: fornicators and adulterers God will judge. Second, those against nature, saying for those who lie with males. 1 Cor. 6:10: nor those who lie with males shall possess the kingdom of God. Then he sets forth the harms of the mouth, and first as to simple lying, saying for liars. Eph. 4:25: putting away lying, speak the truth, etc. Second as to swearing, saying for perjurers. And then he gathers the rest in general, saying and if there be any other thing to sound doctrine, etc. Job 6:30: you will not find iniquity in my tongue, nor will folly sound in my mouth, etc. Tit. 2:1: speak the things that become sound doctrine. Then, when he says which is according to the Gospel, he shows that the Gospel imparts sound doctrine, which he describes in three ways. And first from the end, when he says of glory, namely which it announces, Ps. 95:3: declare his glory among the nations. Second from the author of the glory, when he says of the blessed God. Below, at the end: whom in his own time he shall show, who is the blessed and only mighty King of kings, etc. Third from the minister, when he says which was committed to me. Gal. 2:7: when they had seen that the Gospel of the uncircumcision was committed to me, etc. Then, when he says I give thanks, he proves by experience in himself what he himself had been in the time of the law and what he had obtained in the time of grace. And first he shows what was done concerning himself in each time; second he leads Timothy to imitate him, at the words this precept. Concerning the first he does two things: first he shows what was given to him in the law, and what was given to him in the Gospel; second he assigns the reason, at the words a faithful saying. Likewise the first part is divided into three particles, because first he sets forth the dignity which he obtained in the Gospel; second the sins under which he lay in the state of the law, at the words who before was; third how he was freed, at the words but mercy, etc. But for someone to be a minister of the Gospel, three things are required. First, that it be committed to him. Rom. 10:15: how shall they preach, unless they be sent, etc. Second, fitness, that is, that he be faithful. 1 Cor. 4:2: here now it is required among stewards, that a man be found faithful. Likewise, that he be strong to carry it through. And these three he sets forth in reverse order, and first the third, saying who has strengthened me, etc., namely to carry through the office enjoined on him. Ez. 3:14: the hand of the Lord was with me, strengthening me. The second he sets forth at the words because he counted me faithful, etc. Matt. 24:45: a faithful and prudent servant, whom his lord has set over his household. And this because he sought only the things that were God's. The first indeed he shows, when he says in the ministry, that is, committing this ministry to me. Acts 13:2: separate me Barnabas and Saul for the work to which I have taken them. 2 Cor. 11:23: are they ministers of Christ? So am I. But what sort of man was he in the state of the law? A sinner. And first against God, when he says who before was a blasphemer, namely of the name of Christ. Lev. 24:14: bring forth the blasphemer outside the camp, and let all who heard him lay their hands upon his head, and let all the people stone him. Hence that applied to himself. Likewise against his neighbor, when he says and a persecutor. 1 Cor. 15:9: I am not worthy to be called an apostle, because I persecuted the Church of God. Likewise and injurious, in words and deeds. Jer. 20:10: I heard the reproaches of many, etc. Then, when he says but the mercy of God, he shows how he was freed through Christ. And concerning this he does two things: first he sets forth the mercy that freed him; second he shows that he was superabundantly filled with good things, at the words but it superabounded. As to the first he says but I obtained the mercy of God. Lam. 3:22: it is of the mercies of the Lord that we are not consumed. Rom. 9:18: he has mercy on whom he will, and whom he will he hardens. But on my part there is some excuse of the sin, because I did it ignorantly. He says less, but signifies more, because it is one thing to act unknowingly, another through ignorance; for he acts unknowingly who does not know what he is doing, yet if he knew, he would still do it, as one who, believing he is killing a wild beast, kills his enemy, whom nevertheless he would have killed even more gladly, had he recognized him. But he acts through ignorance who does something that he would not do, if he knew, as one killing his father, whom, if he knew him, he would not kill, whom nevertheless he kills, because he believes him to be an enemy. But Paul acted through ignorance, because if he had known that Christ was the Son of God, he would not have done this. But the Jews did not kill Christ through ignorance, but unknowingly, because if they had known him to be the Christ, they would have killed him even more gladly. Lk. 12:47: the servant who knew the will of his lord, and did not prepare himself, nor did according to his will, shall be beaten with many stripes, etc. But as to the second he says it superabounded, etc. Rom. 5:20: where sin abounded, grace also superabounded. With faith and love. For there he produced the effect of faith through love working, which is in Christ Jesus. Gal. 3:14: in Christ Jesus, that we may receive the promise of the Spirit through faith.”

“But we know that the law is good,.... The apostle says this to prevent an objection that might be made to him, that seeing he bore so hard on such who were fond of being teachers of the law, he was himself against the law, and the preaching and proper use of it; but this he would not have concluded, for he and his fellow labourers in the ministry, and all true believers know, from the Scriptures of truth, from the agreement of the law with the Gospel, and from their own experience, that the law is good, provided it be used in a lawful way, and to lawful purposes: and this is to be understood not of the ceremonial law, which was now disannulled, because of the weakness and unprofitableness of it, so that there was no lawful use of that; but of the moral law, which must needs be good, since the author of it is God, who is only good; and nothing but good can come from him: the law, strictly moral, is a copy of his nature, transcribed out of himself, as well as with his own hands; and is a declaration of his will, and is stamped with his authority, and therefore must be good: the matter of it is good, it contains good, yea, great and excellent things; the matter of it is honestly and morally good, as to love mercy, do justice, and walk humbly with God: and it is pleasantly good to a regenerate man, who loves it, and delights in it after the inner man, and serves it with his spirit; though the carnal mind cannot be subject to it, but rejects it, and rebels against it: and it is also profitably good; for though obedience to it is not profitable to God, yet it is to men; and though eternal life is not obtained hereby, nor any reward given for keeping it, yet in keeping it there is a reward; and that peace is enjoyed, which the transgressors of it are strangers to: it is good in the uses of it, both to sinners and to saints. To sinners it is useful for the knowledge of sin, to convince of it, and bring them to a sense of it, and concern for it, which is effectually done, when the Spirit of God sets in with it, or brings this commandment home to the heart; and if it has not this use, it is sometimes a means of restraining men from sin, which is the use of civil laws among men; and if it has not this, it is of use however to accuse men rightly of sin, and to pronounce justly guilty before God for it, to curse them as they deserve it, and to sentence to condemnation and death: and to believers it is of use, though they are not under it as in the hands of Moses, and as a covenant of works, and are freed from its curse and condemnation, and under no obligation to seek for life and righteousness by it; to them it is of use, to point out to them what is the will of God, and what should be done, and not done; and it is a rule of walk and conversation to them, as in the hands of Christ; and is as a glass to them to behold their own deformity, the impurity of their nature, the plague of their own hearts, and the imperfection of their obedience; by which they see the insufficiency of their own righteousness, how far they are from perfection, and what carnal creatures they are, when compared with this law: and as this serves to put them out of conceit with themselves, so it tends to make Christ and his righteousness more lovely and valuable in their esteem; who has wrought out a righteousness as broad and as long as the law is, and by which it is magnified and made honourable, and has delivered them from its curse and condemnation. And this law is good as it is holy, in its author, nature, and use; and as it is just, requiring just things, and doing that which is just, by acquitting those who are interested in Christ's righteousness, and in condemning those that have no righteousness; and as it is a spiritual and perfect law, which reaches the spirit and soul of man, and is concerned with inward thoughts and motions, as well as outward actions; and especially the end of it, the fulfilling end of it is good, which is Jesus Christ, who was made under it, came to fulfil it, and has answered all the demands of it: so that it must be good, and which cannot be denied, if a man use it lawfully; for if it is used in order to obtain life, righteousness, and salvation by the works of it, or by obedience to it, it is used unlawfully: for the law does not give life, nor can righteousness come by it; nor are, or can men be saved by the works of it; to use the law for such purposes, is to abuse it, as the false teachers did, and make that which is good in itself, and in its proper use, to do what is evil; namely, to obscure and frustrate the grace of God, and make null and void the sufferings and death of Christ. A lawful use of the law is to obey it, as in the hands of Christ, the King of saints, and lawgiver in his church, from a principle of love to him, in the exercise of faith on him, without any mercenary selfish views, without trusting to, or depending on, what is done in obedience to it, but with a view to the glory of God, to testify our subjection to Christ, and our gratitude to him for favours received from him.”

“But we know that the law is good - The law as given by God, is both good in itself and has a good tendency. This is similar to what the apostle had asserted, Rom 7:12-16 : The law is holy; and the commandment is holy, just, and good; see the note on Rom 7:12, etc. If a man use it lawfully - That is, interpret it according to its own spirit and design, and use it for the purpose for which God has given it; for the ceremonial law was a schoolmaster to lead us unto Christ, and Christ is the end of that law for justification to every one that believes. Now those who did not use the law in reference to these ends, did not use it lawfully - they did not construe it according to its original design and meaning.”

“But--"Now we know" (Rom 3:19; Rom 7:14). law is good--in full agreement with God's holiness and goodness. if a man--primarily, a teacher; then, every Christian. use it lawfully--in its lawful place in the Gospel economy, namely, not as a means of a "'righteous man" attaining higher perfection than could be attained by the Gospel alone (Ti1 4:8; Tit 1:14), which was the perverted use to which the false teachers put it, but as a means of awakening the sense of sin in the ungodly (Ti1 1:9-10; compare Rom 7:7-12; Gal 3:21).”
