The Purpose of the Law
Sermons on Galatians
Please turn in your Bibles to Galatians chapter 3 as we continue our study in Paul's letter to the Galatians. Galatians chapter 3. I'm going to take up verses 19 to 25 this evening. Trying to keep it simple. Get the lessons out of it that we can get. The thing that I want to encourage you is that the apostle here is not speaking necessarily or primarily about personal faith. Though that obviously goes into it, what he is dealing with is redemptive history. He's dealing with the relationship between the promise made to Abraham and the covenant made with Israel, who had as its mediator the man Moses, what we might call or what we do call the old covenant. Remember, the idea here is that men came in and said, it's good to believe on the Lord Jesus, but you also need to submit to the Mosaic law so that you may have acceptance with God. And so Paul is dealing with that particular subject. And so that's something that you need to keep in mind when we work our way through verses 19 to 25. Yes, personal faith is involved, to be sure, but the primary focus of the apostle is to deal with the history of redemption, very specifically how the mosaic covenant relates to the Abrahamic promise. So when we read law in this particular section, it is a reference to that mosaic or old covenant. But I'll pick up reading in verse 15 just to remind us of the context in which we're dealing. Brethren, I speak in the manner of men, though it is only a man's covenant. Yet, if it is confirmed, no one annuls or adds to it. Now to Abraham and his seed were the promises made. He does not say and to seeds as of many, but as of one and to your seed, who is Christ. And this, I say that the law, which was four hundred and thirty years later, cannot annul the covenant that was confirmed before by God in Christ, that it should make the promise of no effect. For if the inheritance is of the law, it is no longer a promise. But God gave it to Abraham by promise. What purpose, then, does the law serve? It was added because of transgressions, till the seed should come to whom the promise was made. And it was appointed through angels by the hand of a mediator. Now, a mediator does not mediate for one only, but God is one. Is the law, then, against the promises of God? Certainly not. For if there had been a law given which could have given life, truly righteousness would have been by the law. But the scripture has confined all under sin that the promise by faith in Jesus Christ might be given to those who believe. But before faith came, we were kept under guard by the law, kept for the faith, which would afterward be revealed. Therefore, the law was our tutor to bring us to Christ. that we might be justified by faith. But after faith has come, we are no longer under a tutor. For you are all sons of God through faith in Christ Jesus. For as many of you as were baptized into Christ have put on Christ. There is neither Jew nor Greek. There is neither slave nor free. There is neither male nor female. For you are all one in Christ Jesus. And if you are Christ, Then you are Abraham's seed and heirs according to the promise. Amen. Well, let us pray. Our father in heaven, we come now and we ask that you would fill each one of us with your Holy Spirit, that you would guide our thinking in this very important subject concerning your dealings with men. God, how we thank you for the Lord Jesus, how we thank you for salvation by grace through faith in Him. And our Father, we just pray that you would forgive us now for all of our sins and wash us afresh as we come to the scriptures and grant us the grace to take every thought captive to the obedience of Christ. And as well, God, give us the grace to appreciate the larger scheme, the larger context in which this passage is given. The fact that God is in Christ, reconciling the world unto Himself. How we praise You, Lord, that You've included us in this gracious plan. How we praise You that You have not dealt with us according to our sins. And how we pray that this Gospel would run swiftly and be glorified. And that a great multitude would believe and be saved. And we ask through Jesus Christ our Lord Amen. So remember, last week we considered the priority of the promise in verse 15. He says, I speak in the manner of men, though it is only a man's covenant, yet if it is confirmed, no one annuls or adds to it. When men enter into an agreement, when they sign the God of life, when they shake hands, People don't come along afterwards and add to that or annul it. It is a binding contract. It is a binding covenant. And the same is true, obviously, with reference to God the Lord. Now to Abraham and his seed, where are the promises made? He describes or he identifies the seed here as being the Lord Jesus. The Westminster Larger Catechism asks, With whom is the covenant of grace made? The covenant of grace is made with Christ Jesus as the second Adam and all the elect with him. as a result of his redemptive work. And so Jesus is the seed. Jesus is the one who is the mediator of this better covenant. He goes on to say, and this I say, that the law, which was 430 years later, cannot annul the covenant that was confirmed before by God in Christ. That's the whole point. The law, the Mosaic Code, the Mosaic Covenant did not add stipulations to the promise. It did not add conditions to the promise. The only way that we'll ever be saved is by believing on the Lord Jesus Christ. So that naturally leads the apostle to consider the function of the Mosaic Covenant. And he asked the question concerning the law in verse 19, and then he gives an answer with reference to its purpose in verses 19 and 20. And then he gives some explanation concerning the relationship between the Mosaic code or Mosaic covenant. to the promise made to Abraham in verses 21 to 25. So there is a question concerning the law, the answer with reference to its purpose, and then thirdly, some explanation concerning its relationship to the promise. Now, let's take up this question. Verse 19. What purpose then does the law serve? In other words, if the promise made to Abraham has priority, If the promise made to Abraham is permanent and binding, why in the world would God have made this covenant with Israel through the mediator Moses? Why in the world would this have been introduced? That's what the apostle takes up. He answers it. Very clearly, but before we look at that answer, I just want to make a reference to John Calvin, a quote from John Calvin. What we find in this section is not Paul's exhaustive dealing with the law. He's not dealing with every use, every misuse, everything that has to do with the Mosaic Code. He is specifically dealing with what this context establishes. Calvin said, The law has manifold uses, but Paul confines himself to that which bears on his present subject. He did not propose to inquire in how many ways the law is of advantage to men. It is necessary to put readers on their guard on this point. For very many, I find, have fallen into the mistake of acknowledging no other advantage belonging to the law but what is expressed in this past passage. So the idea is that verses 19 to 25 does not exhaust what the Bible says concerning the law of God. Very often we come to verse 25. After faith has come, we are no longer under a tutor. Well, the tutor was the Mosaic law, therefore we have no law. Well, that's not the conclusion we're supposed to take away from this particular study. The law has manifold uses. The apostle is dealing with one specific aspect of the law in this particular context. So that brings us to consider his answer with reference to the law's purpose. Notice in verse 19, it was added because of transgressions. It was added because of transgressions, till the seed should come to whom the promise was made. It was added because of transgressions. Probably two things are at work here. One is for the purpose of restraining sin. God gave this law in a codified fashion to the nation of Israel to restrain their wickedness. to restrain their evil. Now, law doesn't have the power to change the heart, but it certainly can restrict and hedge in the heartless. And so we need to appreciate that function and that use of the law. It was added because of transgressions, but as well, it was added to reveal sin. The fact that God spoke His law causes men to see their need for a Savior. The fact that God defines for us what is and isn't sin causes us to see our great need, causes us to see our misery. For by the law, Paul says in Romans 3.20, is the knowledge of sin. In Paul's own experience, according to Romans chapter 7, he said, I would not have known covetousness, or rather, I would not have known lust, if the law had not said, do not covet. So this law was added, not to annul the promise, not to add to the promise, not as a means of achieving the promise, but the law was added to restrain the sinfulness of the nation and to reveal to the nation their need for the Lord Jesus, their need for this promised Messiah that would rescue them and save them from their sins as well. Some taking Romans 520 say that this is a reference or that this text also shows that the law was given to multiply or increase transgression. Romans 520 says, moreover, the law entered that the offense may abound. It skirted up. It showed what problem was in man's heart. The law of God comes and reveals that wickedness and hopefully restrains, at least externally or outwardly, that wickedness. But it also serves to multiply the transgression or increase it. Again, crying out to high heaven for atonement, for cleansing, for justification. John Gill said 430 years after the covenant made with Abraham, it did not succeed it. This is the Mosaic covenant, nor take the place of it. And so make it null and void, but was over and above added to it for the sake of restraining transgressions, which had there been no law, men would not have been accountable for them. and they would have gone into them without fear and with impunity. But the law was given to lay a restraint on men by forbidding such and such things on pain of death and also for the detecting, discovering and making known transgressions, what they are, their nature and consequences. These the law charges men with sets them before them in their true light and proper colors and convicts them of them stops their mouths and pronounces them guilty before God. So the Mosaic Covenant came, and specifically that component of law, in order to restrain, reveal, and even increase transgression. To shut their mouths, to show them their need, and to cause them to look forward to the coming of the Lord Jesus Christ, who would take away their sin. Now notice the text again, in verse 19. It was added, because of transgressions, till the seed should come to whom the promise was made. I suspect that this law was given as well to preserve the integrity of Israel. Now, they didn't always do very well on their own. They had a lot of issues. You read the Old Testament and you'll see lots of sin and lots of waywardness and lots of evil and wickedness and covenant breaking. But God, by the law, hedged them in. And one of the purposes for his hedging them in and seeking to keep them relatively pure was so that in the fullness of the time, God sending forth his son would be born of a woman born under the law. It preserved the stock of Israel for the coming of the Lord Jesus. It was prophesied concerning him that he would come from David's line. It was prophesied concerning him that he would be of the tribe of Judah. And so this law functioned to hedge the people in to keep them relatively pure so that Jesus could come in accordance with the prophecies. One man says in terms of Paul's concerns in Galatians, this is very important. I would really urge you to listen. I understand this again is one of those. Big picture, theological, covenant things, sort of things that we don't always traffic in. But as I said last week, covenant theology is the framework by which God is working to save His people from their sins. It's like looking at the blueprint. Now, most of us just like to look at the finished product. But hopefully somebody's looking at the blueprint, checking it out and observing and looking and studying the detail. And that's what covenant theology is. It's the blueprint behind the actual fleshing out of God's redemptive plan. This man says in terms of Paul's concerns in Galatians, it was necessary for there to be a covenant that at a minimum preserved two things. First, memory of the gracious promises made to Abraham and his seed. And it did most certainly do that. The Mosaic covenant made or promoted the memory of those gracious promises made to Abraham and his seed. And he says the second function, to preserve the biological integrity of the seed itself. Sinai's dietary laws and prohibitions against intermarrying with the Gentiles, along with Sinai's calendar and its circumcision, set Abraham's descendants apart from the Gentiles. saving them in some degree from their desire to intermarry with the people of the land until the time came to do away with such a designation forever. There were things necessary to teach via the types and sacrifices of the Old Testament system in order for the work of the coming Christ to make any sense when he appeared. So it laid the framework. It laid the foundation. The sacrificial system taught them without the shedding of blood, there is no remission. The sacrificial system taught them that they needed a priest. The sacrificial system taught them that they needed substitutionary curse bearing. That whole thing was designed to teach, to train, to guard, to supervise, and watch over these people. until the fullness of the time had come." Then notice what he says in verse 19 concerning the law. It was appointed through angels by the hand of a mediator. It was appointed by angels. Stephen refers to the same thing in Acts 7 and verse 53. Hebrews chapter 2 and verse 2 mentions a same or similar thing concerning the law coming by the angels. And many suspect that this comes as a reference from Deuteronomy 33. The Lord came from Sinai and dawned on them from Seir. He shone forth from Mount Paran and He came with ten thousands of saints. From His right hand came a fiery law for them. So the law was appointed by angels. It came by the hand of a mediator. I believe the mediator, according to Galatians 3, 19, is Moses. That is specified in Leviticus 26 and Deuteronomy chapter 5. And I think the point is simply this. This is a tough portion of scripture. I'm not going to lie to you. In fact, verse 20, very often in sort of a preliminary study, I go through the passage. I might write down notes. And around verse 20, I put question marks. I don't have a clue what it means. I know that sounds like an awkward admission from your pastor to say, but every commentator I checked said, this is a tough passage. Some speculate there's 430 takes. As many years between the giving of the promise and the giving of the law, there's that many interpretations of verse 20. It is a tough passage. It is difficult to know specifically what the apostle means. Here's the direction I think, at least, it is going. Notice, verse 19, the law, the covenant made with Moses, was appointed through angels by the hand of a mediator. Remember, when God spoke to Abraham, there were no angels there. There was no mediator there. There was God the Lord alone. God spoke, God commanded, God unilaterally imposed the terms of this arrangement. God alone walked through those pieces that had been separated in terms of sacrifice. God alone took the maledictory oath. If the covenant should be broken, he swore by that ceremony that he would be subject to that same penalty. So while the law is great and while the Mosaic code and covenant is beautiful and supreme and excellent and all these things, it was given by mediation. God dealt very directly with Abraham, again, upholding the priority and the permanence of the promise. And that's the direction I think verse 20 takes it. Now, a mediator does not mediate for one only. Moses mediated between God and Israel, but God is one. The priority of the promise is seen in that this one true and living God acted unilaterally in his promise made to Abraham. That's what I believe is going on, at least to some degree, here in verse 20, highlighting the fact that God the Lord made this promise, the law made with Israel, or the covenant made with Israel, does not null it, does not render it obsolete, and it does not add to it. And then that brings us, thirdly, to consider the explanation concerning the relationship to the promise. Notice in verse 21, again, another question would arise. Is the law then against the promises of God? No. You're thinking wrongly if you have a problem between the Mosaic Covenant and the Abrahamic promise. He says, certainly not. The King James translates it. God forbid. No way. It's not the case, though given by mediation. The Mosaic Covenant was still made by God, the God who made the promise to Abraham. He doesn't make and enact things that are at war with one another. Is the law against the promises of God? Certainly not. Now, notice his proof. For if there had been a law given which could have given life, truly righteousness would have been by the law. The Mosaic Covenant was never intended to impart life. It wasn't a competitor alongside the Abrahamic promise. It wasn't like if some of you want to go with Abraham, great. If you want to go with Moses, great. We'll try and see who makes it to the very end. That wasn't the purpose. The Mosaic Covenant had a very specific and a very defined purpose. It was never given to impart life. It was never given as a means of acceptance with God. It was given to restrain sin, to reveal sin, yea, to even increase sin, and to show men their need for that promise that was made to Abraham. Yea, for the seed that would come from Abraham that would ultimately live, die, and rise again. It's a beautiful piece of logic here. If there had been a law given which could have given life, truly righteousness would have been by the law. What's the implication? That's not the point of the law. Notice back in Galatians 221. I do not set aside the grace of God, for if righteousness comes through the law, then Christ died in vain. They are not competitors. If anything, the Mosaic Covenant functions alongside of the promise to protect the integrity of the people, such until the time that the seed would come. One man, Ronald Fung, not Vincent Chung, but Ronald Fung, said, there is no essential contradiction of the promise by the law, because simply the law is intended to serve the purposes of the promise, which has to do with justification by faith. When Moses stood on Sinai and received the law from God, and then he went down and spoke it to the people, it was never intended to impart life. was intended to protect them, it was intended to define for them, it was intended to restrain them and to reveal certain things, but it was never a means of their acceptance with God. Why is that? The next verse answers, verse 22. But the scripture has confined all under sin, that the promise by faith in Jesus Christ might be given to those who believe. No law could ever be a means of acceptance with God because the scripture has clearly stated we're all under sin. We're all slaves to sin. We've all violated the Holy God. We have all gone astray. There is none righteous. No, not one. The scripture has confined us. It hedges us in. It shuts us in on all sides. The verb indicates no possibility of escape. There's no getting around this fact. The Bible has told us very clearly we're all under sin. Therefore, it is not by law keeping. not by merit, not by the Mosaic Covenant, that we will be accepted before God. He says the Scripture is confined all under sin. That, verse 22, the promise by faith in Jesus Christ, might be given to those who believe. Not to the doers of the law, but to the believers of the Gospel. The believers of the promise by faith in Jesus Christ. And then notice the role of the law prior to the coming of Christ. Verse 23, But before faith came. Again, we're dealing in redemptive history. Abraham believed God and it was accounted to him for righteousness. Moses believed God. David believed God. Faith was present in the Mosaic covenant. Faith was present in the Davidic covenant. Faith was present in the Old Covenant. The idea here is not faith individually. The idea is faith in terms of God's covenantal arrangement. He's talking about the coming of the Lord Jesus. Before faith came, we were kept under guard by the law, kept for the faith, which would afterward be revealed. Faith here refers to the coming of Jesus Christ. What did the Mosaic Covenant do? It kept us under guard. Not us specifically, I believe the use of the pronouns indicates. Prior he's dealing with Gentiles, now he's speaking specifically of Jews. Prior to the arrival of faith, that law, that Mosaic code, that covenant kept us under guard. It hedged us in. I mean, read the Old Testament. You'll see it was a time during Ezra and Nehemiah. The people were intermarrying with pagans. It was in them to do this. But the law served to restrain them. The law served to guard them. The law served to hedge them in such that they would not completely obliterate the lines so that Jesus could come in fulfillment of the promise that He would be the Lion of the tribe of Judah. And then finally, the pedagogical use of the law. Pedagogue is a word that means child tutor or custodian. Literally, a pedagogue was a custodian or a male nurse maid. He was a slave employed in Greek and Roman families to have general charge of a boy in the years from about 6 to 16. This included discipline if the boy needed it. It wasn't a bad thing. This was a good thing. It wasn't just a vicious arrangement. This was a man who went about to supervise, to guard over and watch the young man until he matured. It says he would watch over his outward behavior and attend him both at home and whenever he left from home. So the custodial office or the tutorial office of the Mosaic arrangement, again, was to guard us or guard Israel, to hedge them in, to keep them under control so that they would not totally obliterate the line and the seed. And so the pedagogue, the pedagogical function here, verse 24, therefore the law was our tutor to bring us to Christ that we might be justified by faith. So the law functioned to keep the people together until the fullness of the time when God would send forth his son to live, to die, to rise again, so that everybody looking to him would be justified by faith. So when he concludes by saying, but after faith has come, we are no longer under a tutor, that doesn't mean you and I get to go murder or commit adultery or steal. That's not what he means. He means the Mosaic covenant is no longer binding. The book of Hebrews makes this very clear as well. The old covenant has been replaced by a new covenant, a better covenant, which is founded on better promises. So the covenantal system, called the Mosaic or old, is done and over. This does not mean, however, that there's no place for God's moral law in the lives of his people. That is a question that has to be answered and pursued in other sections of scripture. You cannot, it is irresponsible to come to verse 25 and conclude that the Christian has no place with reference to God's law in his life. That's not the point. The point is the Mosaic covenant as an arrangement. by God imposed for a time to restrain the people, to reveal to the people until the seed should come. Since the seed has come, that arrangement is superseded. It is passed away. It is no more. The issue of God's abiding law, we go elsewhere, and the Bible answers that for us. So in conclusion, three lessons, then we close. The first is concerning the law of God. I realize Paul keeps calling it law. He is referring, obviously, to the Mosaic Covenant. That is the primary feature of the Mosaic Covenant. Not that there wasn't promise in the covenant made with Moses. Not that there wasn't atonement. Not that there wasn't sacrifice. Not that there wasn't priestly mediation. All those things were present. But when you hear Moses in the scripture, you automatically think in terms of law. This is the direction that John is going in John chapter one, John chapter one, verse 16. And of his fullness, Jesus fullness, we have all received and grace for grace. For the law was given through Moses, but grace and truth came through Jesus Christ. Doesn't mean there was no grace and truth during the time of Moses. That's not what it means. Doesn't mean there isn't any law in the time of Jesus. Didn't Jesus say, if you love me, you will keep my commandments. Doesn't John the Apostle say keeping his commandments is not burdensome. Doesn't Paul say, oh, no man anything but to love one another. How does he define love? He goes to the Ten Commandments. Doesn't Paul, writing to the Ephesians, urge upon Gentile children to honor their father and mother, which is the first commandment with promise? So the idea in John 1.17 isn't to say Moses was a wretch, the Old Covenant was a wretched system, it was all bad, everything's miserable. No, it's defining it in terms of its essential feature. For the law was given through Moses, but grace and truth came through Jesus Christ. So, though the old covenant has passed away, the moral law still abides. I've already referred to a few places where that is clear. We have studies that we can do on this particular subject or topic, but you cannot conclude from verse 25 in Galatians 3 that you can go out and do whatever you want. No. has law. God calls us to obedience. God calls us to follow him. John Calvin again, beautiful exposition on this section. I even twittered, Calvin is great on Galatians. That's how much I was moved when I read this section of Galatians. Some of you are going, what's twittered? It's a weird thing that you shouldn't get caught up in. Just kidding. Calvin says, but here the question is again put, is the law so abolished that we have nothing to do with it? Again, if you've not done reading or you have not looked into this whole question of the Christian and the law, verse 25 of Galatians 3 is a huge text to prove that the law has no effect, no place in the life of the believer. Well, now that Christ has come, we don't need that pedagogue. Now that Christ has come, we don't need the law. Now that Christ has come, we don't need that system. We sign about the Mosaic covenant as a whole, not nulling or voiding or adding to the Abrahamic promise. Not dealing with the moral law, which I believe and will argue in other places, other times, transcends the covenant made with Moses. Calvin says, though, but here the question is again, but is the law so abolished that we have nothing to do with it? I answer the law so far as it is a rule of life, a bridle to keep us in the fear of the Lord, a spur to correct the sluggishness of our flesh. So far in short, as it is profitable for doctrine, for reproof, for correction, for instruction and righteousness, that believers may be instructed in every good work. is as much in force as ever and remains untouched. Don't go to Galatians 3.25 and say, well, there you go. We don't have any responsibility to the law. No, we do. The law still has three particular uses. One, to restrain evil. Two, to lead the sinner to Christ by way of showing him and exposing his wickedness. And then a third use of that law is when Jesus justifies us, when we believe the gospel by grace alone, through faith alone and Christ alone, then Jesus points us to the law as a pattern of sanctification, as a pattern of life. How do we know what pleases God? You look at the law. How do we know how to love one another? You look at the law. How do we know how to conduct ourselves in society? You look at the law. How do we know how to conduct ourselves in our workplace? You look at the law. Jesus said, baptizing them in the name of the Father, and of the Son, and of the Holy Spirit, and teaching them to observe all that I have commanded you. Now, we're not to suspect that it's only those things that are in the red letters. It's only those things that Jesus spoke in his earthly ministry. We believe that God is one. We believe that the God who spake through Moses is our Lord Jesus Christ. So we ought to search the entirety of the scripture, looking for those things which are profitable. profitable for doctrine, for reproof, for correction, and for instruction in righteousness. So the law of God is for us, not as a means of justification, but as a means, a pattern, an example of what a sanctified life looks like. Secondly, we need to understand something here about the covenants of God. There is unity. Unity between the covenants. But there's also diversity. It was never an intention of God through Moses to give a law that would impart life. That's not the point of the Mosaic law. It is clearly defined in this particular passage. The Mosaic covenant protected the integrity of the seed until the coming of the large S seed in which the promise made to Abraham would find fulfillment. And then thirdly and finally, this passage speaks to the doctrine of justification. Now, whatever may be difficult in this passage, and I'm sure there's a lot, I'm up here trying to explain it, looking out and people going, okay, what's going on here? I've actually spent time with this passage, thinking through it for a little while, and here I'm trying to give you sort of the fruit of that. But whatever this passage may, or whatever is difficult in this passage, you cannot miss the emphasis on justification by faith alone. Right? So even if Paul's opponents were to walk away scratching their head, what was he talking about there? This much is true. Look at verse 22, the scriptures can find all understand that the promise by faith in Jesus Christ might be given to those who believe verse 23. But before faith came, we were kept under guard by the law, kept for the faith, which would afterward be revealed. Therefore, the law was our tutor to bring us to Christ, that we might be justified by faith. What does Paul want to ram down his opponent's throats? You are not justified by faith plus words. You are not justified by Abraham and Moses. You are not justified by a little of this and a little of that. You are justified solely and alone. by believing the gospel of the Lord Jesus Christ. Whatever may be difficult, whatever may be obscure, in this passage, no force certain, it emphasizes, highlights, and reinforces the truth that salvation is a gracious act of God Most High, given to His elect by virtue of, or through the means of, faith in the Lord Jesus Christ. Do not miss that reality and you will not go wrong. You may never be able to describe or explain Galatians 3.20, but hopefully Galatians 3.22 is very clear, might be given to those who believe. So in conclusion, if you have not believed on the Lord Jesus Christ, come in faith to him. That's God's plan for the ages. to send His Son, who lived in obedience to His law, to die for sinners and to rise again, so that everyone who looks to Him in faith would have everlasting life. Well, let us pray. Father, we thank You for Your Holy Scripture, and we thank You for Your covenantal dealings with men, and thank You that You have included us in this arrangement. And our Father, we pray that you would just grant us grace to go now into a new work week. Give us grace, Father, to shine as lights and to hold forth your word of truth and to demonstrate love to you and love to our fellow man. We just pray, God most high, that you would be well pleased to bless your people, to cause your face to shine upon us, and to grant us that peace of God which does surpass all understanding. And we ask now that you would be glorified in all that we do, and we pray through Christ our Lord. Amen.
