Matthew 5:17–26

¹⁷ “Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. ¹⁸ For truly, I say to you, until heaven and earth pass away, not an iota, not a dot, will pass from the Law until all is accomplished. ¹⁹ Therefore whoever relaxes one of the least of these commandments and teaches others to do the same will be called least in the kingdom of heaven, but whoever does them and teaches them will be called great in the kingdom of heaven. ²⁰ For I tell you, unless your righteousness exceeds that of the scribes and Pharisees, you will never enter the kingdom of heaven.

²¹ “You have heard that it was said to those of old, ‘You shall not murder; and whoever murders will be liable to judgment.’ ²² But I say to you that everyone who is angry with his brother will be liable to judgment; whoever insults his brother will be liable to the council; and whoever says, ‘You fool!’ will be liable to the hell of fire. ²³ So if you are offering your gift at the altar and there remember that your brother has something against you, ²⁴ leave your gift there before the altar and go. First be reconciled to your brother, and then come and offer your gift. ²⁵ Come to terms quickly with your accuser while you are going with him to court, lest your accuser hand you over to the judge, and the judge to the guard, and you be put in prison. ²⁶ Truly, I say to you, you will never get out until you have paid the last penny.

In the name of Jesus. Amen.

This Gospel reading today is all Law. These verses begin a long section of the Sermon on the Mount where Jesus is, basically, giving a long commentary on the Ten Commandments which runs all the way to the end of chapter 5 – thirty-two verses worth of our Lord’s teaching on the Ten Commandments. Now, God’s Law, which is succinctly given to us in the Ten Commandments (Ex. 20:1-17), does a couple different things.^[1] Let me just briefly tell you what they are before we focus in on one.

First and foremost, God’s Law shows us how creation works. It reveals what is good in this life. In other words, the Commandments teach you how to be happy and how to live in perfect harmony with God, harmony with your neighbor, and harmony with the rest of creation. Because God’s Law does this, you can think of it as a ‘curb,’ and keep that term in your mind because we’re going to come back to it in just a bit.

Second, because the Commandments teach us how creation works, they also show us where we are living in a way that is contrary to how creation works. The Law shows us how we have violated God’s will, how we have offended Him, and have earned His wrath because of our sin. In other words, the Law accuses us. It stands there like a perfect, clear mirror showing us what we really look like, and it isn’t a pretty picture.

As far as your salvation is concerned, this is the most important thing the Law does. It accuses you and exposes the fact that you are not what you are created to be. So, when you see yourself in the mirror of God’s Law, run to Him in repentance seeking His mercy which He freely gives to you for the sake of Jesus’ death and resurrection.

Again, as far as your salvation is concerned, this is the most important thing God’s Law does. But! Make sure you notice that the Law is only a mirror because of that first function, the ‘curb,’ which again simply shows us how God has ordered creation.

So, back to the ‘curb.’ Unless you have really poor spatial awareness, you probably don’t think about curbs very often. Maybe, you hit the curb when you’re driving your spouse’s vehicle that has a longer or wider wheelbase than you are used to, but that curb just bumps you back onto the street keeping you off the sidewalk and lawns. Typically, if you hit a curb when you’re driving, it’s no big deal. It just means you’ll need to get your tires realigned a bit sooner.

But know that there are different kinds of curbs. If you’re driving on I-29 or Hwy. 2, there aren’t what we normally call curbs, but there are those rumble strips that shake the car and make a loud noise to keep you from straying off the road. You might hit those rumble strips periodically on a curve or when the wind is blowing exceptionally hard. But there are still other curbs. If you’re driving on the freeways in the Cities, the curb might be a thick, four-foot concrete wall to keep the traffic traveling in opposite directions from colliding. Those, you avoid, and, hopefully, you’ve never hit or scraped one of them because it’ll do extensive damage to your car. Rumble strips, normal neighborhood curbs, and concrete barriers are all types of “curbs” that keep vehicles where they should be – on the road and away from danger.

Now, take that idea of those different types of curbs to God’s Law and the Ten Commandments. We might hear the 5^th Commandment, “Thou shalt not kill,” and think of the curb of the 5^th Command as the thick, four-foot concrete barrier. It’s big, but it’s also quite easy to avoid running into it. You can always see it and know that hitting it would cause significant damage. Because the 5^th Command is so big and impending, you easily avoid it. But just because you’ve never physically murdered someone, don’t think that you’re righteous according to the 5^th Command.

Here, in this Gospel text, Jesus says that the 5^th Command is also a regular curb. Christ says, “Don’t relax on this command because everyone who is angry with his brother is also guilty of murder” (Mt. 5:22a). Jesus shows that the 5^th Command isn’t just a concrete barrier to keep us from physically murdering someone, it’s also a curb that keeps us from being angry toward our neighbor. Again, when you’re driving your vehicle, you might bump a curb a couple times a week or once a month. But just because you don’t think much about your anger toward others doesn’t mean that God doesn’t notice. Even nudging the curb of anger toward your neighbor makes you liable to judgment and earns you an eternity in hell.

Think back to Genesis 4. Before Cain murdered Abel, God asked Cain, “Why are you angry?” (Gen. 4:6). Even though God hadn’t yet given the command, “Thou shalt not kill,” God was warning Cain there with the 5^th Command because Cain was angry. But Cain blew right over the curb of anger that God had constructed and smashed into the concrete barrier of murder.

Jesus goes even further and tells us about the 5^th Command rumble strips. Calling someone a fool is the same as murder (Mt. 5:22b). And Jesus still isn’t done. Christ teaches us that the 5^th Command demands that if we remember that someone has something against us that we must go to them and try to reconcile, or we are violating the 5^th Command (Mt. 5:23-24).

When it comes to keeping the 5^th Command, it’s not enough for you to not physically murder someone or never be angry. It’s not even enough for you to never call someone a fool. You also need to seek reconciliation with others who are angry against you. Otherwise, you have 5^th Commandment blood on your hands. Jesus is teaching here that you’ve run into all kinds of 5^th Commandment curbs. You do it every day. And because of that, you are guilty before God and liable to His eternal judgment.

Jesus, who was the One who spoke the Ten Commandments, clearly spells out what they mean. You could say that He is giving us the “fine print” of the Commands explaining the full, complete picture of what they demand. But don’t misunderstand that either. It isn’t as though the Ten Commandments weren’t enough. They are enough. Imagine you told your teenage kid to clean the kitchen, and all he does is wipe down the exposed counters and leaves a pile of dishes by the sink. (To be clear, this is not an example from my household. My kids know better.) You come into the kitchen and see all the greasy, grimy pots and pans. You’d rightly get after him and say, “I told you to clean the kitchen. Get back in there.”

Here, when Jesus teaches us the “fine print” of the Ten Commandments, we are left with no excuse for hitting any of the curbs of any of the Commandments. Christ says, “Whoever relaxes one of the least of these commandments and teaches others to do the same will be called least in the kingdom of heaven. You need a righteousness that exceeds the goodest [sic.], most moral person you know of, or you will never enter the kingdom of heaven” (Mt. 5:19-20). And when Jesus talks about the “least command,” He is not saying that the Ten Commandments have a ranking where some are more important and some less. No! Christ is saying that the tiniest infraction of any of the Commandments, even refusing to reconcile with someone who is angry with you, makes you unrighteous and means that you are outside the kingdom of heaven. In other words, we’re all in deep, deep trouble. Repent.

Repent and know that Jesus completes and fulfills the Commands in another way than just explaining them more fully. Jesus also keeps all the Commands, all of God’s Law, perfectly and completely – for you. Every aspect of every command was perfectly obeyed by Jesus. And His obedience is yours through faith in Him.

Think of it this way: God is going to grade you on one test, and that is the test of keeping His Law, and you need to get a perfect score, 100%, never hitting any curb – ever, or you will spend eternity in hell. Even with an open book, the best, most righteous person is going to bomb that test. Maybe get a score in the teens or something. But also know God has told you that you can use a partner to take the test. Through faith, Jesus is your Partner for this final exam, and He answers every demand of the Law perfectly. Through faith in Him, His full, complete righteousness is yours. 

And now, He invites you to receive that righteousness as He gives you His righteous Body to eat, and His holy, cleansing, forgiving Blood to drink. So, come to His table and receive His perfect righteousness. Amen.

The peace of God, which surpasses all understanding, will guard your hearts and minds in Christ Jesus. Amen.

^[1] The Formula and Epitome of Concord Art. VI. both talk about the three uses of the Law – 1) curb, 2) mirror, and 3) guide. This sermon is written with the understanding that the 2^nd and 3^rd uses of the Law are both subsets of the 1^st. So, I’m not denying the 3^rduse of the Law in any way. Instead, it is a clear extension of the 1^st use as is the 2^nd.
