Because the law - All law. It is the tendency of law.

Worketh wrath - Produces or causes wrath. While man is fallen, and a sinner, its tendency, so far from justifying him, and producing peace, is just the reverse. It condemns, denounces wrath, and produces suffering. The word "wrath" here is to be taken in the sense of punishment. Romans 2:8. And the meaning is, that the Law of God, demanding perfect purity, and denouncing every sin condemns the sinner, and consigns him to punishment. As the apostle had proved Romans 1; 2; 3 that all were sinners, so it followed that if any attempted to be justified by the Law, they would be involved only in condemnation and wrath.

For where no law is ... - This is a general principle; a maxim of common justice and of common sense. Law is a rule of conduct. If no such rule is given and known, there can be no crime. Law expresses what may be done, and what may not be done. If there is no command to pursue a certain course, no injunction to forbid certain conduct, actions will be innocent. The connection in which this declaration is made here, seems to imply that as the Jews had a multitude of clear laws, and as the Gentiles had the laws of nature, there could be no hope of escape from the charge of their violation. Since human nature was depraved, and people were prone to sin, the more just and reasonable the laws, the less hope was there of being justified by the Law, and the more certainty was there that the Law would produce wrath and condemnation.

Because the law worketh wrath - For law νομος, any law, or rule of duty. No law makes provision for the exercise of mercy, for it worketh wrath, οργην, punishment, for the disobedient. Law necessarily subjects the transgressor to punishment; for where no law is - where no rule of duty is enacted and acknowledged, there is no transgression; and where there is no transgression there can be no punishment, for there is no law to enforce it. But the Jews have a law, which they have broken; and now they are exposed to the penal sanctions of that law; and, if the promises of pardon without the works of the law, do not extend to them, they must be finally miserable, because they have all broken the law, and the law exacts punishment. This was a home stroke, and the argument is unanswerable.

Because the law worketh wrath,.... Not the wrath of man, though that is sometimes stirred up through the prohibitions of the law, to which the carnal mind of man is enmity, but the wrath of God the law is so far from justifying sinners, that it curses and condemns them; and when it comes into the heart and is let into the conscience of a sinner, it fills with terrible apprehensions of the wrath of God, and a fearful looking for of his judgment and fiery indignation:

for where no law is, there is no transgression; (r); a sort of a proverbial expression: had the law of Moses not been given, there was the law of nature which sin is a transgression of; but the law of Moses was added for the better discovery and detection of sin, which would not have been so manifest without it, and which may be the apostle's sense; that where there is no law, there is no knowledge of any transgression; and so the Ethiopic version reads the words, "if the law had not come, there would have been none who would have known sin"; but the law is come, and there is a law by which is the knowledge of sin, and therefore no man can be justified by it; since that convinces him of sin, and fills him with a sense of divine wrath on account of it.

(r) Caphtor, fol. 10. 1.

{13} Because the law worketh wrath: for where no law is, there is no transgression.

(13) A reason of the first confirmation, why the promise cannot be apprehended by the law: because the law does not reconcile God and us, but rather proclaims his anger against us, because no man can fully keep it.

4:15 Because the law worketh wrath. The law threatens punishment to all who break its enactments, and since none keep it perfectly, it works punishment for all.

For where no law is, there is no trangression. Whereas, if no law had been given, there could be no transgression of its demands.

4:15 Because the law - Considered apart from that grace, which though it was in fact mingled with it, yet is no part of the legal dispensation, is so difficult, and we so weak and sinful, that, instead of bringing us a blessing, it only worketh wrath; it becomes to us an occasion of wrath, and exposes us to punishment as transgressors. Where there is no law in force, there can be no transgression of it.

Margin transgression

Sin. See Scofield Note: "Rom 3:23".

15. Because the law worketh wrath-has nothing to give to those who break is but condemnation and vengeance.

for where there is no law, there is no transgression-It is just the law that makes transgression, in the case of those who break it; nor can the one exist without the other.

4:13-22 The promise was made to Abraham long before the law. It points at Christ, and it refers to the promise, Ge 12:3. In Thee shall all families of the earth be blessed. The law worketh wrath, by showing that every transgressor is exposed to the Divine displeasure. As God intended to give men a title to the promised blessings, so he appointed it to be by faith, that it might be wholly of grace, to make it sure to all who were of the like precious faith with Abraham, whether Jews or Gentiles, in all ages. The justification and salvation of sinners, the taking to himself the Gentiles who had not been a people, were a gracious calling of things which are not, as though they were; and this giving a being to things that were not, proves the almighty power of God. The nature and power of Abraham's faith are shown. He believed God's testimony, and looked for the performance of his promise, firmly hoping when the case seemed hopeless. It is weakness of faith, that makes a man lie poring on the difficulties in the way of a promise. Abraham took it not for a point that would admit of argument or debate. Unbelief is at the bottom of all our staggerings at God's promises. The strength of faith appeared in its victory over fears. God honours faith; and great faith honours God. It was imputed to him for righteousness. Faith is a grace that of all others gives glory to God. Faith clearly is the instrument by which we receive the righteousness of God, the redemption which is by Christ; and that which is the instrument whereby we take or receive it, cannot be the thing itself, nor can it be the gift thereby taken and received. Abraham's faith did not justify him by its own merit or value, but as giving him a part in Christ.
