THE LAW OF GOD

Excerpted from my 

Holding Fast Our Confession: The Westminster Confession of Faith and its Biblical Teaching

THE LAW OF GOD

WCF CHAPTER 19, Sections 1-4. Of the Law of God.

I. God gave to Adam a law, as a covenant of works, by which he bound him and all his posterity to personal, entire, exact, and perpetual obedience; promised life upon the fulfilling, and threatened death upon the breach of it; and endued him with power and ability to keep it.

II. This law, after his Fall, continued to be a perfect rule of righteousness; and, as such, was delivered by God upon mount Sinai in ten commandments, and written in two tables; the first four commandments containing our duty toward God, and the other six our duty to man.

III. Besides this law, commonly called moral, God was pleased to give to the people of Israel, as a Church under age, ceremonial laws, containing several typical ordinances, partly of worship, prefiguring Christ, his graces, actions, sufferings, and benefits; and partly holding forth divers instructions of moral duties. All which ceremonial laws are now abrogated under the New Testament.

IV. To them also, as a body politic, he gave sundry judicial laws, which expired together with the state of that people, not obliging any other, now, further than the general equity thereof may require. 

Introduction

Why is God having His Gospel proclaimed throughout the whole earth? Why is Christ having His Good News spread among all the nations? Surely, it’s because the Gospel is the message of salvation to all peoples. But, if the Gospel is the Good News of salvation, the question necessarily arises: What are we being salvaged or saved from? Well, the answer to that is that we are being saved from God’s punishment upon our sins. But what is sin that we need to be saved from God’s punishment of it? Well, those of you who know your Catechism will immediately think of Q & A 14: Sin is any want of conformity unto, or transgression of, the law of God.

So we see then that according to the Westminster Shorter Catechism sin is disobeying or not conforming to God’s law in any way. Therefore, the Gospel is about God saving people who have broken His Law from receiving their just desert.

Now, some people out there on the street, or maybe even some people who come to church, will be wondering where, how, and when they have broken and are breaking God’s Law. Therefore, that’s the kind of thing we need to be looking at in the following. It’s important to know these things otherwise you won’t see a real need for the Gospel.

The Law of God as Given to Adam

There’s a very moving verse pertaining to God’s Law found in one of the Psalms. It should be the lament of every Gospel-believing Christian. It’s a verse that is an expression of a person who has a real burden for the lost. It’s a deep heartfelt expression of a man who knows what sin is.

Now, you might think it strange that an Old Testament saint can have a real evangelical burden for the lost. But if you think it strange, then perhaps you’ve forgotten that the Old Testament is full of Christ and His Gospel of salvation. For what did Jesus say of the Old Testament Scriptures? “…these are they which testify of Me” (John 5:39).

What were the Old Testament Scriptures saying that Jesus was coming to do? Well, that question is answered and summed up in the words of the angel who spoke to Joseph about Mary: “And she will bring forth a Son, and you shall call His name JESUS, for He will save His people from their sins” (Matt. 1:21). He was coming to save His people from their sins. What is sin? Again, it’s the breaking of the Law of God. The Gospel then, is about Jesus saving His people from their breaking of God’s Law.

You’ll be wondering where that verse is found, the one uttered by the Old Testament saint who had a burden for the lost. But, whatever you do, don’t detach his burden for the lost from his burden to see God glorified. For wasn’t that the way of it for the Pharisees, for example? The Pharisees had forgotten about God’s glory in evangelism; and everything else for that matter. And as such, their evangelism was just about man reaching out to man. The Pharisees would cross land and sea to win one convert (Matt. 23:15). But they wouldn’t give God the glory for any conversions to their religion. Why not? It’s because their burden for the lost did not flow from a love for God, for His Law, and for His glory alone.

The Apostle speaks for us where he says, “For the love of Christ compels us…” Our love for the lost, therefore, ought to be the overflow and outflow of our love for God in Christ. Therefore, it’s because we have a burden for the glory of God that we have a burden for the lost. Anything other than this is not true Biblical evangelism. Rather it is just another form humanism – man reaching out to man, like the Pharisees.

In a word, our burden for the lost ought to be because they are breaking something that belongs to God. They are breaking God’s Law. And if they are breaking God’s Law, then our God’s honour is at stake. For sin, by definition, is the breaking of the Law of God.

Let’s look at it this way: when a rock star goes off his rocker and trashes a hotel room, he is trashing someone else’s property. Sin is the trashing of the property of God. Well, I ask you: Who made you, and who made me? Whose property are we? If God made us, we are God’s property. And if sin is the destruction of God’s property, and Hell is the everlasting destruction of God’s property, we need to start caring about God and His property, don’t we?

Would you want to see God’s property destroyed and thrown into Hell? No? Well, that’s what evangelism is all about! But our focus must be on God. It must first and foremost be on the honour and glory of God if we are to have a true burden for the lost, and not just some romantic humanistic notion of salvation. 

It is God’s honour – it is God’s good name – it is God’s glory that is at stake. This, the Psalmist could clearly see when he penned the words of Psalm 119:136. Here they are – read them carefully: “Rivers of water run down from my eyes, because men do not keep Your law.” Think about those words when you wash the dishes. Think about them when you take a shower. Think about them when you go shopping. Think about them at church, at work, and at play.

Rivers of water run down from my eyes. Why? Because men don’t keep God’s law. If you think God’s Law is just some fuzzy Old Testament thing, if you think God’s Law is just some straitjacket the Pharisees used to wear, if you have any other notion of God’s Law than the view expressed in that verse by the Old Testament Psalmist, then you are missing something very important. The breaking of God’s Law is something to weep about. It is not something to be taken lightly. People are going to Hell because they are breaking God’s Law.

But where and when did all this Law-breaking of mankind begin? Well, on the sixth day of creation God gave His Law to Adam as a Covenant of Works. How did God present His Law to Adam? Did He hand Adam two tablets of stone? No! He wrote His Law on Adam’s heart. Romans 2:14-15 testifies to this truth: “…for when Gentiles, who do not have the law, by nature do the things in the law, these, although not having the law, are a law to themselves, who show the work of the law written in their hearts, their conscience also bearing witness, and between themselves their thoughts accusing or else excusing them…”

We see then that the Law of God is written in the heart of man. So, in answer to our question: When did God write His Law in the heart of man? We say that God wrote His Law on the heart of man when He created man in His image. Therefore, the Law of God is part of the constitution or makeup of man.

So, what’s the Psalmist shedding rivers of tears over? Well, he is able to clearly see what has become of the image of God. For he sees that there is a war raging all around him. What war is that? It’s the one man is waging with God who made him. That’s what the Psalmist means when he says to God, “…men do not keep Your law.”

Because he has the glory of God in view, he is aware of the war that is raging all around him. And war is Hell! Think about it: if God lifted the corner of the thick, dark veil and gave us a glimpse of Hell, rivers of water would run down from our eyes. Why? Because men don’t keep God’s Law. It is failure to keep the Law of God that lands you in Hell. And that failure began all the way back with Adam in the Garden.

When God created Adam, He gave him a law as a covenant of works, (Hos. 6:7). By writing His Law on Adam’s heart God bound Adam and all his descendants, to personal, entire, exact, and perpetual obedience. Adam, therefore, was mankind’s representative before God. And by giving Adam an outward test – the forbidden fruit – God threatened death for breach of it, which is to say that God threatened Adam with death for the breaking of His Law, which He had written in man’s heart. And conversely, God promised Adam life for the fulfilling of His Law.

The misery and death we see all around is proof enough that man failed to keep the covenant. Had Adam not united with the Devil in covenant against God, then mankind would have received the unlosable everlasting life promised in the Covenant of Works. So take note then that to break the Covenant of Works is to break the Law of God. And to break the Law of God is to be at war with God. And to be at war with God means misery and death, ultimately, everlasting death in Hell.

So, the Law God gave to Adam was built into the very structure of Adam’s being. In other words, the Law of God is a major aspect of who man is. But all mankind became buckled in the heat of Adam’s rage against God in the Garden! We became like the angry drunk who wants to punch everyone out just for looking at him!

If you keep in mind that before the Fall Adam had the power and the ability to keep the Law of God, you’ll begin to understand a bit more the gravity of his sin. It wasn’t the drink that made Adam sin. It wasn’t the devil who made Adam sin. He was clear-thinking, sober, and in perfect control of all his faculties when he broke God’s Law. But after he sinned, he, and all of mankind after him, became as a staggering drunk. The proverbial bull in a china shop doesn’t quite paint the picture.

The Lord’s prophet Hosea sums it up best when God says through him in 13:9, “O Israel, thou hast destroyed thyself…” (Yes, the KJV says it best, but don’t miss the good news), “O Israel, thou hast destroyed thyself; but in Me is thine help.”

So, Adam destroyed mankind by breaking the Law God gave him. This he did by eating the forbidden fruit. But always remember that our help is in God. That is the heart of the Gospel – the Good News.

Our help is in God. As the Psalmist says, “God is our refuge and strength, a very present help in trouble” (Psa. 46:1).

The Law of God as Given to Israel

When God gave His Law to man in the beginning, He wrote it on the tablet of man’s heart. When God gave His Law to Israel, He wrote it on two tablets of stone. However, we’ve seen already that whether the Law of God was written on man’s fleshy tablet or on clay tablets, it remains the exact same Law of God. We saw this when we noted in Romans 2:14-15 that the Gentiles, who unlike Israel who also had the Law of God written on stone, still showed that it was written on their hearts. Therefore, the same Law of God has been from the beginning of creation the same rule for mankind – whether written on stone or in the heart.

To be sure, we understand that God wrote His Law on man’s heart in positive terms. In other words, it was all to do with what man was to do, not what he was not to do. It was written in terms of “Thou shalt…” not in terms of “Thou shalt not…” The “Thou shalt not…” presupposes a knowledge sin.

Regarding the Law of God as it was given to Israel through Moses, we know that the opposite of what is commanded is forbidden and that the opposite of what is forbidden is commanded. Therefore, to use an example, if we consider the 8th Commandment, which is: You shall not steal, we can see that, put positively, it becomes: Be honest.

When we keep this in mind, we have no trouble seeing that the Law of God was given in positive terms to man in the beginning. Therefore, the Law written on man’s heart in the beginning (i.e., the Ten Commandments) would have been something like this:

 

1.        Worship God exclusively.

2.        Worship God spiritually.

3.        Worship God sincerely.

4.       Worship God as He will be worshipped.

5.        Respect authority.

6.        Respect the life and rights of others.

7.        Be pure and loyal.

8.       Be honest.

9.        Be truthful.

10.     Be happy and content.[1]

So, we see then that the Ten Commandments given by God to Israel is simply a restatement of the Law of God given to man in the beginning. The only difference being that the Law given to Israel presupposes man’s sin. Therefore, when rivers of water run down from the Psalmist’s eyes because men don’t keep God’s Law, he is talking about all men (i.e., mankind), not just Israelites! Thus, when we see it in the light of God’s Law given to all mankind, we get a better insight into the burden the Psalmist had for the lost.

The thinking of the Psalmist would run something like the following: “God, You made man in Your own image and likeness. You wrote Your Law on his heart. But all have rebelled against You. They have destroyed themselves!” Isaiah puts the same thought like this in Isaiah 24:5-6: “The earth is also defiled under its inhabitants, because they have transgressed the laws, changed the ordinance, broken the everlasting covenant. Therefore, the curse has devoured the earth, and those who dwell in it are desolate. Therefore, the inhabitants of the earth are burned, and few are left.” War against God is a burning Hell that can only get worse.

The Law God gave to Israel on Mount Sinai presupposes that mankind has broken the everlasting covenant as it was administered pre-Fall. Adam broke the Covenant of Works when he rebelled against God and ate the forbidden fruit. The Covenant of Works was the way the everlasting covenant of God was administered on earth before sin came into the world. The Law given to Israel on Mount Sinai was the everlasting covenant of God as it was administered post Fall from the time of Moses till Christ.

We call the administration of the everlasting covenant that began immediately after the Fall of man, the Covenant of Grace. The Covenant of Grace is simply the Gospel of Jesus Christ by another name. There was grace surrounding the giving of the Law of God to man in the beginning. God graciously made man in His own image and likeness. God graciously wrote His Law on man’s heart. God graciously entered into the Covenant of Works with man. God graciously gave Adam a wife. God graciously put the man and his wife in a beautiful fruit orchard. And on and on the grace of God goes regarding man in the beginning.

There was grace surrounding the giving of the Law to Israel on Mount Sinai: “I am the LORD your God, who brought you out of the land of Egypt, out of the house of bondage. You shall have no other gods before Me…” etc., etc. But the grace of God is seen most clearly after man rebels against God. For God could very easily have just wiped all mankind from the face of the earth. But He didn’t. Why not? For the sake of His only begotten Son, that’s why He saved creation, the world, the cosmos.

This salvation – this saving of the world – was depicted by the Ceremonial Law God also had given to Israel. The Ceremonial Laws centred mostly round the Temple. These Ceremonial Laws included such things as the sacrificial system, which clearly pointed to the supreme sacrifice of Christ to come. Christ is the Lamb of God that takes away the sin of the world (John 1:29). The Passover depicted what Christ was coming to do. And so did the other Old Testament sacrament of Circumcision. To be sure Circumcision came in with Abraham who was four hundred odd years before Moses. But nevertheless, all the Ceremonial Laws of Israel ended when the One they pointed too came.

Included in these Ceremonial Laws were matters pertaining to worship at the Temple. But they prefigured the graces of Christ, His actions, His sufferings, and His benefits. But, what need is there for a picture when you have the reality of the thing pictured? Therefore, when the Word became flesh, lived, died, and was resurrected, the pictures were no longer needed.

But God also gave to Israel certain Judicial Laws, or Civil Laws. Though there is some overlapping between the Ceremonial and the Judicial Laws, the Ceremonial Laws were mostly ecclesiastical, i.e., having to do with the church in the Old Testament. As mentioned, the Ceremonial Laws were abrogated with the advent of Christ. But the Judicial Laws or Civil Laws continued till Israel ended as a political body. Old Testament Israel ended as a political entity with the demolition of the Temple in 70AD. However, though the Ceremonial Law (as it was administered) disappeared in its entirety, the general equity or the general principles from the Judicial Law remains valid today.

A prime example of this remaining general principle of Old Testament Judicial Law might be Deuteronomy 22:8: “When you build a new house, then you shall make a parapet for your roof, that you may not bring guilt of bloodshed on your household if anyone falls from it.”

When they begged John Calvin to come back to Geneva after they had booted him out, he began to implement the general equity of Old Testament Judicial Law. So, safety railings began to appear on roofs and stairways etc. Open sewers became closed sewers, (Deut. 23:13). The general principles of Old Testament safety and sanitation were put into practice for a better Geneva.

Safety fences around backyard swimming pools are a modern-day application of the general equity of Old Testament Judicial Law. But I’m sure that you can see that this kind of thing regarding safety and sanitation (hygiene) demonstrates that we all have moral responsibilities. When we speak of moral responsibility, we are talking about the Law of God given to man. Therefore, all our moral responsibilities are summarized in Ten Commandments. The Ten Commandments are God’s Moral Law.

The Ceremonial and Judicial Law of Old Testament Israel were the application of God’s Moral Law in the Ecclesiastical and Civil spheres. Therefore, all men ought to keep the Law of God whether in church or civil affairs. Why? Surely we ought to keep the Law of God for His honour and glory.

Societies run smoothest where God’s Law is cheerfully obeyed.

Conclusion

If you have properly understood that God gave His Law to man in the beginning as an act of grace, and if you have properly understood that God gave His Law to Israel as an act of grace, then you will see clearly why rivers of water were running down from the eyes of the Psalmist. For then, like the Psalmist, you will have understood that men, by not keeping God’s Law, are trampling the grace of God underfoot!

The grace of the Law is that it shows us up as morally bankrupt sinners. Therefore, it demonstrates our need of a Saviour. God has sent a Saviour into the world in the Person of His only begotten Son Jesus Christ. He was typified throughout the Old Testament. But now we see Him clearly in New Testament times. Jesus Christ is the Law of God incarnate. He perfectly does what the Law commands us to do. He perfectly loves God and His neighbour as Himself. Jesus Christ, therefore, is the embodiment of the Law of God.

Jesus Christ is what you and I should be but are not because of our sin. Therefore, trust in His perfect law-keeping alone to save you from the punishment due to you for your breaking of God’s Law. For Jesus Christ saves sinners from their law-breaking and the punishment thereof. That’s what God’s Covenant of Grace is all about. That’s the essence of the Gospel of Jesus Christ.

And just one last thing before we finally conclude, let me ask a couple of questions: 1. What are the wages of sin? And 2. What is the shortest verse in the Bible? The wages of sin is death (Rom. 6:23a). And the shortest verse in the Bible is John 11:35: “Jesus wept.”

Do you think Psalm 119:136 sheds some light on why Jesus wept at the tomb of His dead friend Lazarus? “Rivers of water run down from my eyes, because men do not keep Your law.”
