Vers. 21, 22. The Law not contrary to the Divine Promise.—1. It is the way of some to make one Scripture contradict another, yet their bold allegations will be found always false, and truth to be every most consonant and never contrary to itself. 2. So exact and full is the righteousness required in order to life, and so far short do all mankind come of it, that no works of our own, done in obedience to the law, can amount to that righteousness. 3. Though all men by nature be under sin, it is a matter of no small difficulty to convince any man of it. The work of the law, accusing, convincing, or condemning the sinner, is compared to the work of a judge detaining a malefactor in prison which is not effectuated but with force and violence. 4. The law by its threatenings prepares and necessitates the soul to embrace salvation by faith in the Christ revealed in the promise.—Fergusson.
Ver. 22. The Great Prison; or, All concluded under Sin.—1. Satan does indeed draw and drive men into sin—this is the accursed work of his restless, Sabbath-less life; and when he has got them there he binds them fast and will not let them flee from his toils. He builds a high wall of sin all round them so that they shall not look over it into the goodly land beyond, and here he shuts them up together, sinner with sinner, a never-ending ghastly multitude, that they may encourage and pamper each other in wickedness, and that no example, no voice of holiness, may ever reach and startle them. But God never drove, never drew, any man into sin. He is calling us to come out from the deadly land, from the loathsome, plague-breathing dungeon. So, when the Scripture concludes, or shuts all men up together under sin, it is not by driving them into sin, but for the sake of calling them out of it. 2. With all the light of the Scripture shining around us, with the law of God ever sounding in our ears, and the life of Christ set continually before us, how prone are we to forget our sinfulness, to turn away from the thought of it, to fancy we are as good as we need be, and that, though we might certainly be better, yet it does not matter much! How apt are we still to forget that we are concluded under sin, to forget that we are shut up in a prison! Although the souls of so many millions are lying around us, bloated with the poison of sin, how tardily do we acknowledge that the poison by which they perished must also be deadly to us! 3. Suppose you were to be carried before an earthly court of justice, and that one sweeping accusation were to be brought against you; suppose you were found guilty, and the excuse you set up were the complete proof of your guilt,—what would follow? The judge would straightway pass sentence upon you, and you would be condemned to suffer punishment according to the measure of your offence. And must we not expect that the course of things should be the very same when you are carried before a heavenly court of justice? 4. When a man’s eyes are opened to see the prison in which he is shut up, to see and feel the chains that are fast bound round his soul and have eaten into it; when he has learnt to see and know that the pleasures, whatever they may, of sin are only, like the flesh-pots of Egypt, intoxicating drugs, given to him to deprive him of all sense of his captivity,—then will he long for a deliverer, rejoice on hearing of his approach, hail him when he comes in view, and follow him whithersoever he may lead. As unbelief is the one great universal sin, in which all mankind are concluded, as it is only from having let slip our faith in God that we have yielded our hearts to the temptations of the world and given ourselves up to its idolatries, so it is only through faith that we can be brought back to God—that we can receive the promise given to those who believe.—J. C. Hare.
Ver. 23. “Shut up unto the faith.” The Reasonableness of Faith.—The mode of conception is military. The law is made to act the part of a sentry, guarding every avenue but one, and that one leads those, who are compelled to take it, to the faith of the Gospel. Out of the leading varieties of taste and sentiment which obtain in the present age we may collect something which may be turned into an instrument of conviction for reclaiming men from their delusions and shutting them up to the faith.
I. There is the school of natural religion.—It is founded on the competency of the human mind to know God by the exercise of its own faculties, to clothe Him in the attributes of its own demonstration, to serve Him by a worship and a law of its own discovery, and to assign to Him a mode of procedure in the administration of this vast universe upon the strength and plausibility of its own theories. They recognise the judicial government of God over moral and accountable creatures. They hold there is a law. One step more, and they are fairly shut up to the faith. That law has been violated.
II. There is the school of classical morality.—It differs from the former school in one leading particular. It does not carry in its speculations so distinct and positive a reference to the Supreme Being. Our duties to God are viewed as a species of moral accomplishment, the effect of which is to exalt and embellish the individual. We ask them to look at man as he is and compare him with man as they would have him to be. If they find that he falls miserably short of their ideal standard of excellence, what is this but making a principle of their own the instrument of shutting them up unto the faith of the Gospel, or at least shutting them up into one of the most peculiar of its doctrines, the depravity of our nature, or the dismal ravage which the power of sin has made upon the moral constitution of the species? This depravity the Gospel proposes to do away.
III. There is the school of fine feeling and poetical sentiment.—It differs from the school of morality in this—the one makes virtue its idol because of its rectitude, the other makes virtue its idol because of its beauty, and the process of reasoning by which they are shut up unto the faith is the same in both. However much we may love perfection and aspire after it, yet there is some want, some disease, in the constitution of man which prevents his attainment of it, that there is a feebleness of principle about him, that the energy of his practice does not correspond to the fair promises of his fancy, and however much he may delight in an ideal scene of virtue and moral excellence, there is some lurking malignity in his constitution which, without the operation of that mighty power revealed to us in the Gospel, makes it vain to wish and hopeless to aspire after it.—Dr. Thomas Chalmers.
Vers. 24, 25. The Law our Schoolmaster.—There was a time when God put His world under a schoolmaster; then it would have been preposterous to apply faith. There is a time when a larger spirit has come, and then it would be going back to use law.
I. The uses of restraint in the heart’s education.—1. The first use of law is to restrain from open violence. It is necessary for those who feel the inclination to evil, and so long as the inclination remains so far must a man be under law. Imagine a governor amidst a population of convicts trusting to high principle. Imagine a parent having no fixed hours, no law in his household, no punishment for evil. There is a morbid feeling against punishment; but it is God’s method.
2. The second use of restraint is to show the inward force of evil.—A steam-engine at work in a manufactory is so quiet and gentle that a child might put it back. But interpose a bar of iron many inches thick, and it cuts through as if it were so much leather. Introduce a human limb—it whirls round, and the form of man is in one moment a bleeding, mangled, shapeless mass. It is restraint that manifests this unsuspected power. In the same way law discovers the strength of evil in our hearts.
3. The third use is to form habits of obedience.—In that profession which is specially one of obedience—the military profession—you cannot mistake the imparted type of character. Immediate, prompt obedience, no questioning “why?” Hence comes their decision of character. Hence, too, their happiness. Would you have your child, happy, decided, manly? Teach him to obey. It is an error to teach a child to act on reason, or to expect reasons why a command is given. Better it is that he should obey a mistaken order than be taught to see that it is mistaken. A parent must be the master in his own house.
