This purity is evident—1. In the moral law, or law of nature. 2. In the ceremonial law. 3. In the allurements annexed to it, for keeping it, and the affrightments to restrain from the breaking of it. 4. In the judgments inflicted for the violation of it.

1. In the moral law: which is therefore dignified with the title of Holy, twice in one verse (Rom. vii. 12): “Wherefore, the law is holy, and the commandment is holy, just, and good;” it being the express image of God’s will, as our Saviour was of his person, and bearing a resemblance to the purity of his nature. The tables of this law were put into the ark, that, as the mercy seat was to represent the grace of God, so the law was to represent the holiness of God (Ps. xix. 1). The Psalmist, after he had spoken of the glory of God in the heavens, wherein the power of God is exposed to our view, introduceth the law, wherein the purity of God is evidenced to our minds (ver. 7, 8, &c.): “Perfect, pure, clean, righteous,” are the titles given to it. It is clearer in holiness than the sun is in brightness; and more mighty in itself, to command the conscience, than the sun is to run its race. As the holiness of the Scripture demonstrates the divinity of its Author; so the holiness of the law doth the purity of the Lawgiver.

(1.) The purity of this law is seen in the matter of it. It prescribes all that becomes a creature towards God, and all that becomes one creature towards another of his own rank and kind. The image of God is complete in the holiness of the first table, and the righteousness of the second; which is intimated by the apostle (Eph. iv. 24), the one being the rule of what we owe to God, the other being the rule of what we owe to man: there is no good but it enjoins, and no evil but it disowns. It is not sickly and lame in any part of it; not a good action, but it gives it its due praise; and not an evil action, but it sets a condemning mark upon. The commands of it are frequently in Scripture called judgments, because they rightly judge of good and evil; and are a clear light to inform the judgment of man in the knowledge of both. By this was the understanding of David enlightened to know every false way, and to “hate it” (Ps. cxix. 104). There is no case can happen, but may meet with a determination from it; it teaches men the noblest manner of living alife like God himself; honorably for the Lawgiver, and joyfully for the subject. It directs us to the highest end; sets us at a distance from all base and sordid practices; it proposeth light to the understanding, and goodness to the will. It would tune all the strings, set right all the orders of mankind: it censures the least mote, countenanceth not any stain in the life. Not a wanton glance can meet with any justification from it (Matt. v. 28); not a rash anger but it frowns upon (ver. 22). As the Lawgiver wants nothing as an addition to his blessedness, so his law wants nothing as a supplement to its perfection (Deut. iv. 2). What our Saviour seems to add, is not an addition to mend any defects, but a restoration of it from the corrupt glosses, wherewith the Scribes and Pharisees had eclipsed the brightness of it: they had curtailed it, and diminished part of its authority, cutting off its empire over the least evil, and left its power only to check the grosser practices. But Christ restores it to the due extent of its sovereignty, and shows it those dimensions in which the holy men of God considered it as “exceeding broad” (Ps. cxix. 96), reaching to all actions, all motions, all circumstances attending them; full of inexhaustible treasures of righteousness. And though this law, since the fall, doth irritate sin, it is no disparagement, but a testimony to the righteousness of it; which the apostle manifests by his “Wherefore” (Rom. vii. 8), “sin, taking occasion by the commandment, wrought in me all manner of concupiscence;” and repeating the same sense (ver. 11), subjoins a “Wherefore” (ver. 12), “Wherefore the law is holy.” The rising of men’s sinful hearts against the law of God, when it strikes with its preceptive and minatory parts upon their consciences, evidenceth the holiness of the law and the Lawgiver. In its own nature it is a directing rule, but the malignant nature of sin is exasperated by it; as an hostile quality in a creature will awaken itself at the appearance of its enemy. The purity of this beam, and transcript of God, bears witness to a greater clearness and beauty in the sun and original. Undefiled streams manifest an untainted fountain.

(2.) It is seen in the manner of its precepts. As it prescribes all good, and forbids all evil, so it doth enjoin the one, and banish the other as such.The laws of men command virtuous things; not as virtuous in themselves, but as useful for human society; which the magistrate is the conservator of, and the guardian of justice.[904] The laws of men contain not all the precepts of virtue, but only such as are accommodated to their customs, and are useful to preserve the ligaments of their government. The design of them is not so much to render the subjects good men, as good citizens: they order the practice of those virtues that may strengthen civil society, and discountenance those vices only which weaken the sinews of it: but God, being the guardian of universal righteousness, doth not only enact the observance of all righteousness, but the observance of it as righteousness. He commands that which is just in itself, enjoins virtues as virtues, and prohibits vices as vices: as they are profitable or injurious to ourselves, as well as to others. Men command temperance and justice; not as virtues in themselves, but as they preventdisorder and confusion in a commonwealth; and forbid adultery and theft, not as vices in themselves, but as they are intrenchments upon property; not as hurtful to the person that commits them, but as hurtful to the person against whose right they are committed. Upon this account, perhaps, Paul applauds the holiness of the law of God in regard of its own nature, as considered in itself, more than he doth the justice of it in regard of man, and the goodness and conveniency of it to the world (Rom. vii. 12); the law is holy twice, and just and good but once.

(3.) In the spiritual extent of it. The most righteous powers of the world do not so much regard in their laws what the inward affections of their subjects are: the external acts are only the objects of their decrees, either to encourage them if they be useful, or discourage them if they be hurtful to the community. And, indeed, they can do no other, for they have no power proportioned to inward affections, since the inward disposition falls not under their censure; and it would be foolish for any legislative power to make such laws, which it is impossible for it to put in execution. They can prohibit the outward acts of theft and murder, but they cannot command the love of God, the hatred of sin, the contempt of the world; they cannot prohibit unclean thoughts, and the atheism of the heart. But the law of God surmounts in righteousness all the laws of the best‑regulated commonwealths in the world: it restrains the licentious heart, as well as the violent hand; it damps the very first bubblings of corrupt nature, orders a purity in the spring, commands a clean fountain, clean streams, clean vessels. It would frame the heart to an inward, as well as the life to an outward righteousness, and make the inside purer than the outside. It forbids the first belchings of a murderous or adulterous intention: it obligeth a man as a rational creature, and therefore exacts a conformity of every rational faculty, and of whatsoever is under the command of them. It commands the private closet to be free from the least cobweb, as well as the outward porch to be clean from mire and dirt. It frowns upon all stains and pollutions of the most retired thoughts: hence the apostle calls it a “spiritual law” (Rom. vii. 14), as not political, but extending its force further than the frontiers of the man; placing its ensigns in the metropolis of the heart and mind, and curbing with its sceptre the inward motions of the spirit, and commanding over the secrets of every man’s breast.

(4.) In regard of the perpetuity of it. The purity and perpetuity of it are linked together by the Psalmist (Ps. xix. 9): “The fear of the Lord is clean, enduring for ever;” the fear of the Lord, that is, that law which commands the fear and worship of God, and is the rule of it. And, indeed, God values it at such a rate, that rather than part with a tittle, or let the honor of it lie in the dust, he would not only let “heaven and earth pass away,” but expose his Son to death for the reparation of the wrong it had sustained. So holy it is, that the holiness and righteousness of God cannot dispense with it, cannot abrogate it, without despoiling himself of his own being: it is a copy of the eternal law. Can he ever abrogate the command of love to himself, without showing some contemptof his own excellency and very being? Before he can enjoin a creature not to love him, he must make himself unworthy of love, and worthy of hatred; this would be the highest unrighteousness, to order us to hate that which is only worthy of our highest affections. So God cannot change the first command, and order us to worship many gods; this would be against the excellency and unity of God:for God cannot constitute another God, or make anything worthy of an honor equal with himself.[905] Those things that are good, only because they are commanded, are alterable by God: those things that are intrinsically and essentially good, and therefore commanded, are unalterable as long as the holiness and righteousness of God stand firm. The intrinsic goodness of the moral law, the concern God hath for it; the perpetuity of the precepts of the first table, and the care he hath had to imprint the precepts of the second upon the minds and consciences of men, as the Author of nature for the preservation of the world, manifests the holiness of the Lawmaker and Governor.

2. His holiness appears in the ceremonial law: in the variety of sacrifices for sin, wherein he writ his detestation of unrighteousness in bloody characters. His holiness was more constantly expressed in the continual sacrifices, than in those rarer sprinklings of judgments now and then upon the world; which often reached, not the worst, but the most moderate sinners, and were the occasions of the questioning of the righteousness of his providence both by Jews and Gentiles. In judgments his purity was only now and then manifest: by his long patience, he might be imagined by some reconciled to their crimes, or not much concerned in them; but by the morning and evening sacrifice he witnessed a perpetual and uninterrupted abhorrence of whatsoever was evil. Besides those, the occasional washings and sprinklings upon ceremonial defilements, which polluted only the body, gave an evidence, that everything that had a resemblance to evil, was loathsome to him. Add, also, the prohibitions of eating such and such creatures that were filthy; as the swine that wallowed in the mire, a fit emblem for the profane and brutish sinner; which had a moral signification, both of the loathsomeness of sin to God, and the aversion themselves ought to have to everything that was filthy.

3. This holiness appears in the allurements annexed to the law for keeping it, and the affrightments to restrain from the breaking of it. Both promises and threatenings have their fundamental root in the holiness of God, and are both branches of this peculiar perfection. As they respect the nature of God, they are declarations of his hatred of sin, and his love of righteousness; the one belong to his threatenings, the other to his promises; both join together to represent this divine perfection to the creature, and to excite to an imitation in the creature. In the one, God would render sin odious, because dangerous, and curb the practice of evil, which would otherwise be licentious; in the other, he would commend righteousness, and excite a love of it, which would otherwise be cold. By there God suits the two great affections of men, fear and hope;both the branches of self‑love in man: the promises and threatenings are both the branches of holiness in God. The end of the promises is the same with the exhortation the apostle concludes from them (2 Cor. vii. 1); “Having these promises, let us cleanse ourselves from all filthiness of flesh and spirit, perfecting holiness in the fear of God.” As the end of precept is to direct, the end of threatenings is to deter from iniquity, so that the promises is to allure to obedience. Thus God breathes out his love to righteousness in every promise; his hatred of sin in every threatening. The rewards offered in the one, are the smiles of pleased holiness; and the curses thundered in the other, are the sparklings of enraged righteousness.

4. His holiness appears in the judgment inflicted for the violation of this law. Divine holiness is the root of Divine justice, and Divine justice is the triumph of Divine holiness. Hence both are expressed in Scripture by one word of righteousness, which sometimes signifies the rectitude of the Divine nature, and sometimes the vindicative stroke of his arm (Ps. ciii. 6); “The Lord executeth righteousness and judgment for all that are oppressed.” So (Dan. ix. 7) “Righteousness (that is, justice) belongs to thee.” The vials of his wrath are filled from his implacable aversion to iniquity. All penal evils shower down upon the heads of wicked men, spread their root in, and branch out from, this perfection. All the dreadful storms and tempests in the world are blown up by it. Why doth he “rain snares, fire and brimstone, and a horrible tempest!” Because “the righteous Lord loveth righteousness” (Ps. xi. 6, 7). And, as was observed before, when he was going about the dreadfulest work that ever was in the world, the overturning the Jewish state, hardening the hearts of that unbelieving people, and cashiering a nation, once dear to him, from the honor of his protection; his holiness, as the spring of all this, is applauded by the seraphims (Isa. vi. 3, compared with ver. 9–11), &c. Impunity argues the approbation of a crime, and punishment the abhorrency of it.The greatness of the crime, and the righteousness of the Judge, are the first natural sentiments that arise in the minds of men upon the appearance of Divine judgments in the world, by those that are near them;[906] as, when men see gibbets erected, scaffolds prepared, instruments of death and torture provided, and grievous punishments inflicted, the first reflection in the spectator is the malignity of the crime, and the detestation the governors are possessed with.

(1.) How severely hath he punished his most noble creatures for it! The once glorious angels, upon whom he had been at greater cost than upon any other creatures, and drawn more lively lineaments of his own excellency, upon the transgression of his law, are thrown into the furnace of justice, without any mercy to pity them (Jude 6). And though there were but one sort of creatures upon the earth that bore his image, and were only fit to publish and keep up his honor below the heavens, yet, upon their apostasy, though upon a temptation from a subtle and insinuating spirit, the man, with all his posterity, is sentenced to misery in life, and death atlast; and the woman, with all her sex, have standing punishments inflicted on them, which, as they begun in their persons, were to reach as far as the last member of their successive generations. So holy is God, that he will not endure a spot in his choicest work. Men, indeed, when there is a crack in an excellent piece of work, or a stain upon a rich garment, do not cast it away; they value it for the remaining excellency, more than hate it for the contracted spot; but God saw no excellency in his creature worthy regarding, after the image of that which he most esteemed in himself was defaced.
