Galatians 3 · Part 4

The Twofold Purpose of the Law

The Law has a twofold purpose. One purpose is civil. God has ordained civil laws to punish crime. Every law is given to restrain sin. Does it not then make men righteous? No. In refraining from murder, adultery, theft, or other sins, I do so under compulsion because I fear the jail, the noose, the electric chair. These restrain me as iron bars restrain a lion and a bear. Otherwise they would tear everything to pieces. Such forceful restraint cannot be regarded as righteousness, rather as an indication of unrighteousness. As a wild beast is tied to keep it from running amuck, so the Law bridles mad and furious man to keep him from running wild. The need for restraint shows plainly enough that those who need the Law are not righteous, but wicked men who are fit to be tied. No, the Law does not justify.

The first purpose of the Law, accordingly, is to restrain the wicked. The devil gets people into all kinds of scrapes. Therefore God instituted governments, parents, laws, restrictions, and civil ordinances. At least they help to tie the devil’s hands so that he does not rage up and down the earth. This civil restraint by the Law is intended by God for the preservation of all things, particularly for the good of the Gospel that it should not be hindered too much by the tumult of the wicked. But Paul is not now treating of this civil use and function of the Law.

The second purpose of the Law is spiritual and divine. Paul describes this spiritual purpose of the Law in the words, “Because of transgressions,” i.e., to reveal to a person his sin, blindness, misery, his ignorance, hatred, and contempt of God, his death, hell, and condemnation.

This is the principal purpose of the Law and its most valuable contribution. As long as a person is not a murderer, adulterer, thief, he would swear that he is righteous. How is God going to humble such a person except by the Law? The Law is the hammer of death, the thunder of hell, and the lightning of God’s wrath to bring down the proud and shameless hypocrites. When the Law was instituted on Mount Sinai it was accompanied by lightning, by storms, by the sound of trumpets, to tear to pieces that monster called self-righteousness. As long as a person thinks he is right he is going to be incomprehensibly proud and presumptuous. He is going to hate God, despise His grace and mercy, and ignore the promises in Christ. The Gospel of the free forgiveness of sins through Christ will never appeal to the self-righteous.

This monster of self-righteousness, this stiff-necked beast, needs a big axe. And that is what the Law is, a big axe. Accordingly, the proper use and function of the Law is to threaten until the conscience is scared stiff.

The awful spectacle at Mount Sinai portrayed the proper use of the Law. When the children of Israel came out of Egypt a feeling of singular holiness possessed them. They boasted: “We are the people of God. All that the Lord hath spoken we will do” (Ex. 19:8). This feeling of holiness was heightened when Moses ordered them to wash their clothes, to refrain from their wives, and to prepare themselves all around. The third day came and Moses led the people out of their tents to the foot of the mountain into the presence of the Lord. What happened? When the children of Israel saw the whole mountain burning and smoking, the black clouds rent by fierce lightning flashing up and down in the inky darkness, when they heard the sound of the trumpet blowing louder and longer, shattered by the roll of thunder, they were so frightened that they begged Moses: “Speak thou with us, and we will hear: but let not God speak with us, lest we die” (Ex. 20:19). I ask you, what good did their scrubbing, their snow-white clothes, and their continence do them? No good at all. Not a single one could stand in the presence of the glorious Lord. Stricken by the terror of God, they fled back into their tents, as if the devil were after them.

The Law is meant to produce the same effect today which it produced at Mount Sinai long ago. I want to encourage all who fear God, especially those who intend to become ministers of the Gospel, to learn from the Apostle the proper use of the Law. I fear that after our time the right handling of the Law will become a lost art. Even now, although we continually explain the separate functions of the Law and the Gospel, we have those among us who do not understand how the Law should be used. What will it be like when we are dead and gone?

We want it understood that we do not reject the Law as our opponents claim. On the contrary, we uphold the Law. We say the Law is good if it is used for the purposes for which it was designed, to check civil transgression, and to magnify spiritual transgressions. The Law is also a light like the Gospel. But instead of revealing the grace of God, righteousness, and life, the Law brings sin, death, and the wrath of God to light. This is the business of the Law, and here the business of the Law ends, and should go no further.

The business of the Gospel, on the other hand, is to quicken, to comfort, to raise the fallen. The Gospel carries the news that God for Christ’s sake is merciful to the most unworthy sinners, if they will only believe that Christ by His death has delivered them from sin and everlasting death unto grace, forgiveness, and everlasting life. By keeping in mind the difference between the Law and the Gospel we let each perform its special task. Of this difference between the Law and the Gospel nothing can be discovered in the writings of the monks or scholastics, nor for that matter in the writings of the ancient fathers. Augustine understood the difference somewhat. Jerome and others knew nothing of it. The silence in the Church concerning the difference between the Law and the Gospel has resulted in untold harm. Unless a sharp distinction is maintained between the purpose and function of the Law and the Gospel, the Christian doctrine cannot be kept free from error.

Verse 19. It was added because of transgressions.

In other words, that transgressions might be recognized as such and thus increased. When sin, death, and the wrath of God are revealed to a person by the Law, he grows impatient, complains against God, and rebels. Before that he was a very holy man; he worshipped and praised God; he bowed his knees before God and gave thanks, like the Pharisee. But now that sin and death are revealed to him by the Law he wishes there were no God. The Law inspires hatred of God. Thus sin is not only revealed by the Law; sin is actually increased and magnified by the Law.

The Law is a mirror to show a person what he is like, a sinner who is guilty of death, and worthy of everlasting punishment. What is this bruising and beating by the hand of the Law to accomplish? This, that we may find the way to grace. The Law is an usher to lead the way to grace. God is the God of the humble, the miserable, the afflicted. It is His nature to exalt the humble, to comfort the sorrowing, to heal the broken-hearted, to justify the sinners, and to save the condemned. The fatuous idea that a person can be holy by himself denies God the pleasure of saving sinners. God must therefore first take the sledge-hammer of the Law in His fists and smash the beast of self-righteousness and its brood of self-confidence, self-wisdom, self-righteousness, and self-help. When the conscience has been thoroughly frightened by the Law it welcomes the Gospel of grace with its message of a Savior who came into the world, not to break the bruised reed, nor to quench the smoking flax, but to preach glad tidings to the poor, to heal the broken-hearted, and to grant forgiveness of sins to all the captives.

Man’s folly, however, is so prodigious that instead of embracing the message of grace with its guarantee of the forgiveness of sin for Christ’s sake, man finds himself more laws to satisfy his conscience. “If I live,” says he, “I will mend my life. I will do this, I will do that.” Man, if you don’t do the very opposite, if you don’t send Moses with the Law back to Mount Sinai and take the hand of Christ, pierced for your sins, you will never be saved.

When the Law drives you to the point of despair, let it drive you a little farther, let it drive you straight into the arms of Jesus who says: “Come unto me, all ye that labour and are heavy laden, and I will give you rest.”

Verse 19. Till the seed should come to whom the promise was made.

The Law is not to have its say indefinitely. We must know how long the Law is to put in its licks. If it hammers away too long, no person would and could be saved. The Law has a boundary beyond which it must not go. How long ought the Law to hold sway? “Till the seed should come to whom the promise was made.”

That may be taken literally to mean until the time of the Gospel. “From the days of John the Baptist,” says Jesus, “until now the kingdom of heaven suffereth violence, and the violent take it by force. For all the prophets and the law prophesied until John” (Matthew 11:12, 13). When Christ came the Law and the ceremonies of Moses ceased.

Spiritually, it means that the Law is not to operate on a person after he has been humbled and frightened by the exposure of his sins and the wrath of God. We must then say to the Law: “Mister Law, lay off him. He has had enough. You scared him good and proper.” Now it is the Gospel’s turn. Now let Christ with His gracious lips talk to him of better things, grace, peace, forgiveness of sins, and eternal life.

Verse 19. And it was ordained by angels in the hand of a mediator.

The Apostle digresses a little from his immediate theme. Something occurred to him and he throws it in by the way. It occurred to him that the Law differs from the Gospel in another respect, in respect to authorship. The Law was delivered by the angels, but the Gospel by the Lord Himself. Hence, the Gospel is superior to the Law, as the word of a lord is superior to the word of his servant.

The Law was handed down by a being even inferior to the angels, by a middleman named Moses. Paul wants us to understand that Christ is the mediator of a better testament than mediator Moses of the Law. Moses led the people out of their tents to meet God. But they ran away. That is how good a mediator Moses was.

Paul says: “How can the Law justify when that whole sanctified people of Israel and even mediator Moses trembled at the voice of God? What kind of righteousness do you call that when people run away from it and hate it the worst way? If the Law could justify, people would love the Law. But look at the children of Israel running away from it.”

The flight of the children of Israel from Mount Sinai indicates how people feel about the Law. They don’t like it. If this were the only argument to prove that salvation is not by the Law, this one Bible history would do the work. What kind of righteousness is this law-righteousness when at the commencement exercises of the Law Moses and the scrubbed people run away from it so fast that an iron mountain, the Red Sea even, could not have stopped them until they were back in Egypt once again? If they could not hear the Law, how could they ever hope to perform the Law?

If all the world had stood at the mountain, all the world would have hated the Law and fled from it as the children of Israel did. The whole world is an enemy of the Law. How, then, can anyone be justified by the Law when everybody hates the Law and its divine author?

All this goes to show how little the scholastics know about the Law. They do not consider its spiritual effect and purpose, which is not to justify or to pacify afflicted consciences, but to increase sin, to terrify the conscience, and to produce wrath. In their ignorance the papists spout about man’s good will and right judgment, and man’s capacity to perform the Law of God. Ask the people of Israel who were present at the presentation of the Law on Mount Sinai whether what the scholastics say is true. Ask David, who often complains in the Psalms that he was cast away from God and in hell, that he was frantic about his sin, and sick at the thought of the wrath and judgment of God. No, the Law does not justify

Verse 20. Now a mediator is not a mediator of one.

Here the Apostle briefly compares the two mediators: Moses and Christ. “A mediator,” says Paul, “is not a mediator of one.” He is necessarily a mediator of two: The offender and the offended. Moses was such a mediator between the Law and the people who were offended at the Law. They were offended at the Law because they did not understand its purpose. That was the veil which Moses put over his face. The people were also offended at the Law because they could not look at the bare face of Moses. It shone with the glory of God. When Moses addressed the people he had to cover his face with that veil of his. They could not listen to their mediator Moses without another mediator, the veil. The Law had to change its face and voice. In other words, the Law had to be made tolerable to the people.

Thus covered, the Law no longer spoke to the people in its undisguised majesty. It became more tolerable to the conscience. This explains why men fail to understand the Law properly, with the result that they become secure and presumptuous hypocrites. One of two things has to be done: Either the Law must be covered with a veil and then it loses its full effectiveness, or it must be unveiled and then the full blast of its force kills. Man cannot stand the Law without a veil over it. Hence, we are forced either to look beyond the Law to Christ, or we go through life as shameless hypocrites and secure sinners.

Paul says: “A mediator is not a mediator of one.” Moses could not be a mediator of God only, for God needs no mediator. Again, Moses could not be a mediator of the people only. He was a mediator between God and the people. It is the office of a mediator to conciliate the party that is offended and to placate the party that is the offender. However, Moses’ mediation consisted only in changing the tone of the Law to make it more tolerable to the people. Moses was merely a mediator of the veil. He could not supply the ability to perform the Law.

What do you suppose would have happened if the Law had been given without a mediator and the people had been denied the services of a go-between? The people would have perished, or in case they had escaped they would have required the services of another mediator to preserve them alive and to keep the Law in force. Moses came along and he was made the mediator. He covered his face with a veil. But that is as much as he could do. He could not deliver men’s consciences from the terror of the Law. The sinner needs a better mediator.

That better mediator is Jesus Christ. He does not change the voice of the Law, nor does He hide the Law with a veil. He takes the full blast of the wrath of the Law and fulfills its demands most meticulously.

Of this better Mediator Paul says: “A mediator is not a mediator of one.” We are the offending party; God is the party offended. The offense is of such a nature that God cannot pardon it. Neither can we render adequate satisfaction for our offenses. There is discord between God and us. Could not God revoke His Law? No. How about running away from God? It cannot be done. It took Christ to come between us and God and to reconcile God to us. How did Christ do it? “Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross” (Col. 2:14).

This one word, “mediator,” is proof enough that the Law cannot justify. Otherwise we should not need a mediator.

In Christian theology the Law does not justify. In fact it has the contrary effect. The Law alarms us, it magnifies our sins until we begin to hate the Law and its divine Author. Would you call this being justified by the Law?

Can you imagine a more arrant outrage than to hate God and to abhor His Law? What an excellent Law it is. Listen: “I am the Lord thy God, which have brought thee out of the land of Egypt, out of the house of bondage. Thou shalt have no other gods . . . showing mercy unto thousands . . . honor thy father and thy mother: that thy days may be long upon the land . . . ” (Ex. 20:2, 3, 6, 12). Are these not excellent laws, perfect wisdom? “Let not God speak with us, lest we die,” cried the children of Israel. Is it not amazing that a person should refuse to hear things that are good for him? Any person would be glad to hear, I should think, that he has a gracious God who shows mercy unto thousands. Is it not amazing that people hate the Law that promotes their safety and welfare, e.g., “Thou shalt not kill; thou shalt not commit adultery; thou shalt not steal”?

The Law can do nothing for us except to arouse the conscience. Before the Law comes to me I feel no sin. But when the Law comes, sin, death, and hell are revealed to me. You would not call this being made righteous. You would call it being condemned to death and hell-fire.

Verse 20. But God is one.

God does not offend anybody, therefore He needs no mediator. But we offend God, therefore we need a mediator. And we need a better mediator than Moses. We need Christ.

Verse 21. Is the law then against the promises of God?

Before he digressed Paul stated that the Law does not justify. Shall we then discard the Law? No, no. It supplies a certain need. It supplies men with a needed realization of their sinfulness. Now arises another question: If the Law does no more than to reveal sin, does it not oppose the promises of God? The Jews believed that by the restraint and discipline of the Law the promises of God would be hastened, in fact earned by them.

Paul answers: “Not so. On the contrary, if we pay too much attention to the Law the promises of God will be slowed up. How can God fulfill His promises to a people that hates the Law?”

Verse 21. God forbid.

God never said to Abraham: “In thee shall all the nations of the earth be blessed because thou hast kept the Law.” When Abraham was still uncircumcised and without the Law or any law, indeed, when he was still an idol worshiper, God said to him: “Get thee out of thy country, etc.; I am thy shield, etc.; In thy seed shall all the nations of the earth be blessed.” These are unconditional promises which God freely made to Abraham without respect to works.

This is aimed especially at the Jews who think that the promises of God are impeded by their sins. Paul says: “The Lord is not slack concerning His promises because of our sins, or hastens His promises because of any merit on our part.” God’s promises are not influenced by our attitudes. They rest in His goodness and mercy.

Just because the Law increases sin, it does not therefore obstruct the promises of God. The Law confirms the promises, in that it prepares a person to look for the fulfillment of the promises of God in Christ.

The proverb has it that Hunger is the best cook. The Law makes afflicted consciences hungry for Christ. Christ tastes good to them. Hungry hearts appreciate Christ. Thirsty souls are what Christ wants. He invites them: “Come unto me, all ye that labour and are heavy laden, and I will give you rest.” Christ’s benefits are so precious that He will dispense them only to those who need them and really desire them.

Verse 21. For if there had been a law given which could have given life, verily righteousness should have been by the law.

The Law cannot give life. It kills. The Law does not justify a person before God; it increases sin. The Law does not secure righteousness; it hinders righteousness. The Apostle declares emphatically that the Law of itself cannot save.

Despite the intelligibility of Paul’s statement, our enemies fail to grasp it. Otherwise they would not emphasize free will, natural strength, the works of supererogation, etc. To escape the charge of forgery they always have their convenient annotation handy, that Paul is referring only to the ceremonial and not to the moral law. But Paul includes all laws. He expressly says: “If there had been a law given.”

There is no law by which righteousness may be obtained, not a single one. Why not?

Verse 22. But the Scripture hath concluded all under sin.

Where? First in the promises concerning Christ in Genesis 3:15 and in Genesis 22:18, which speak of the seed of the woman and the seed of Abraham. The fact that these promises were made unto the fathers concerning Christ implies that the fathers were subject to the curse of sin and eternal death. Otherwise why the need of promises?

Next, Holy Writ “concludes” all under sin in this passage from Paul: “For as many as are of the works of the law are under the curse.” Again, in the passage which the Apostle quotes from Deuteronomy 27:26, “Cursed is every one that continueth not in all things which are written in the book of the law to do them.” This passage clearly submits all men to the curse, not only those who sin openly against the Law, but also those who sincerely endeavor to perform the Law, inclusive of monks, friars, hermits, etc.

The conclusion is inevitable: Faith alone justified without works. If the Law itself cannot justify, much less can imperfect performance of the Law or the works of the Law, justify.

Verse 22. That the promise by faith of Jesus Christ might be given to them that believe.

The Apostle stated before that “the Scripture hath concluded all under sin.” Forever? No, only until the promise should be fulfilled. The promise, you will recall, is the inheritance itself or the blessing promised to Abraham, deliverance from the Law, sin, death, and the devil, and the free gift of grace, righteousness, salvation, and eternal life. This promise, says Paul, is not obtained by any merit, by any law, or by any work. This promise is given. To whom? To those who believe. In whom? In Jesus Christ.

Verse 23. But before faith came.

The Apostle proceeds to explain the service which the Law is to render. Previously Paul had said that the Law was given to reveal the wrath and death of God upon all sinners. Although the Law kills, God brings good out of evil. He uses the Law to bring life. God saw that the universal illusion of self-righteousness could not be put down in any other way but by the Law. The Law dispels all self-illusions. It puts the fear of God in a man. Without this fear there can be no thirst for God’s mercy. God accordingly uses the Law for a hammer to break up the illusion of self-righteousness, that we should despair of our own strength and efforts at self-justification.

Verse 23. But before faith came, we were kept under the law, shut up unto the faith which should afterwards be revealed.

The Law is a prison to those who have not as yet obtained grace. No prisoner enjoys the confinement. He hates it. If he could he would smash the prison and find his freedom at all cost. As long as he stays in prison he refrains from evil deeds. Not because he wants to, but because he has to. The bars and the chains restrain him. He does not regret the crime that put him in jail. On the contrary, he is mighty sore that he cannot rob and kill as before. If he could escape he would go right back to robbing and killing.

The Law enforces good behavior, at least outwardly. We obey the Law because if we don’t we will be punished. Our obedience is inspired by fear. We obey under duress and we do it resentfully. Now what kind of righteousness is this when we refrain from evil out of fear of punishment? Hence, the righteousness of the Law is at bottom nothing but love of sin and hatred of righteousness.

All the same, the Law accomplishes this much, that it will outwardly at least and to a certain extent repress vice and crime.

But the Law is also a spiritual prison, a veritable hell. When the Law begins to threaten a person with death and the eternal wrath of God, a man just cannot find any comfort at all. He cannot shake off at will the nightmare of terror which the Law stirs up in his conscience. Of this terror of the Law the Psalms furnish many glimpses.

The Law is a civil and a spiritual prison. And such it should be. For that the Law is intended. Only the confinement in the prison of the Law must not be unduly prolonged. It must come to an end. The freedom of faith must succeed the imprisonment of the Law.

Happy the person who knows how to utilize the Law so that it serves the purposes of grace and of faith. Unbelievers are ignorant of this happy knowledge. When Cain was first shut up in the prison of the Law he felt no pang at the fratricide he had committed. He thought he could pass it off as an incident with a shrug of the shoulder. “Am I my brother’s keeper?” he answered God flippantly. But when he heard the ominous words, “What hast thou done? the voice of thy brother’s blood crieth unto me from the ground,” Cain began to feel his imprisonment. Did he know how to get out of prison? No. He failed to call the Gospel to his aid. He said: “My punishment is greater than I can bear.” He could only think of the prison. He forgot that he was brought face to face with his crime so that he should hurry to God for mercy and for pardon. Cain remained in the prison of the Law and despaired.

As a stone prison proves a physical handicap, so the spiritual prison of the Law proves a chamber of torture. But this it should only be until faith be revealed. The silly conscience must be educated to this. Talk to your conscience. Say: “Sister, you are now in jail all right. But you don’t have to stay there forever. It is written that we are ‘shut up unto faith which should afterwards be revealed.’ Christ will lead you to freedom. Do not despair like Cain, Saul, or Judas. They might have gone free if they had called Christ to their aid. Just take it easy, Sister Conscience. It’s good for you to be locked up for a while. It will teach you to appreciate Christ.”

How anybody can say that he by nature loves the Law is beyond me. The Law is a prison to be feared and hated. Any unconverted person who says he loves the Law is a liar. He does not know what he is talking about. We love the Law about as well as a murderer loves his gloomy cell, his straight-jacket, and the iron bars in front of him. How then can the Law justify us?

Verse 23. Shut up unto the faith which should afterwards be revealed.

We know that Paul has reference to the time of Christ’s coming. It was then that faith and the object of faith were fully revealed. But we may apply the historical fact to our inner life. When Christ came He abolished the Law and brought liberty and life to light. This He continues to do in the hearts of the believers. The Christian has a body in whose members, as Paul says, sin dwells and wars. I take sin to mean not only the deed but root, tree, fruit, and all. A Christian may perhaps not fall into the gross sins of murder, adultery, theft, but he is not free from impatience, complaints, hatreds, and blasphemy of God. As carnal lust is strong in a young man, in a man of full age the desire for glory, and in an old man covetousness, so impatience, doubt, and hatred of God often prevail in the hearts of sincere Christians. Examples of these sins may be garnered from the Psalms, Job, Jeremiah, and all the Sacred Scriptures.
