Old Testament Reading: Psalm 110

“A PSALM OF DAVID. The LORD says to my Lord: ‘Sit at my right hand, until I make your enemies your footstool.’ The LORD sends forth from Zion your mighty scepter. Rule in the midst of your enemies! Your people will offer themselves freely on the day of your power, in holy garments; from the womb of the morning, the dew of your youth will be yours. The LORD has sworn and will not change his mind, ‘You are a priest forever after the order of Melchizedek.’ The Lord is at your right hand; he will shatter kings on the day of his wrath. He will execute judgment among the nations, filling them with corpses; he will shatter chiefs over the wide earth. He will drink from the brook by the way; therefore he will lift up his head.” (Psalm 110, ESV)

New Testament Reading: Luke 20:41-44

“But he said to them, ‘How can they say that the Christ is David’s son? For David himself says in the Book of Psalms, ‘The Lord said to my Lord, ‘Sit at my right hand, until I make your enemies your footstool.’’ David thus calls him Lord, so how is he his son?” (Luke 20:41–44, ESV)

Introduction

The passage open before us today is small but weighty. 

To help us feel the weight of it, I think it is important to see this passage as the conclusion to the series of questions that the religious elite within Israel asked Jesus, beginning at Luke 20:1. Those questions, remember, all had to do with authority. Jesus claimed to have authority as the King of God’s eternal kingdom, and the religious elite questioned it so as to undermine it, because they were threatened by it.

Do not forget that Jesus had entered Jerusalem triumphantly. He entered riding on a colt, the foal of a donkey. This was to fulfill the prophecy of Zechariah 9:9, which says, “Rejoice greatly, O daughter of Zion! Shout aloud, O daughter of Jerusalem! Behold, your king is coming to you; righteous and having salvation is he, humble and mounted on a donkey, on a colt, the foal of a donkey.” You and I live in a representative democracy or republic, not a kingdom, so we might fail to appreciate the great power and authority that Kings have. Kingly authority is supreme. Kingly authority is unchecked. Do not forget that when Jesus entered Jerusalem, he was received as a King. 

Luke tells us that “As [Jesus] was drawing near to [Jerusalem]… the whole multitude of his disciples began to rejoice and praise God with a loud voice for all the mighty works that they had seen, saying, ‘Blessed is the King who comes in the name of the Lord! Peace in heaven and glory in the highest!’” (Luke 19:37–38, ESV). Clearly, the disciples of Jesus regarded him to be the promised King of God’s kingdom. When his disciples shouted,  “Blessed is the King who comes in the name of the Lord!”, the Pharisees in the crowd were greatly troubled by this. “Teacher, rebuke your disciples”, they said (Luke 19:39, ESV). But Jesus would not rebuke them. He answered the Pharisees, saying, “I tell you, if these were silent, the very stones would cry out” (Luke 19:40, ESV). The point is this: when Jesus entered Jerusalem, he entered with the authority of a King. 

Furthermore, when Jesus drew near to the city of Jerusalem, he wept over it and, with the authority of a prophet, declared that it would soon be destroyed, saying, “For the days will come upon you, when your enemies will set up a barricade around you and surround you and hem you in on every side and tear you down to the ground, you and your children within you. And they will not leave one stone upon another in you, because you did not know the time of your visitation” (Luke 19:43–44, ESV).

Finally, after Jesus entered Jerusalem, he came to the temple and cleansed it. He cleansed it, as if he owned the place. He cleansed it with priestly authority as he drove out those who sold within its courts. After this, Jesus began to teach authoritatively within the temple. 

We should not be surprised, therefore, that those with authority within Old Covenant Israel felt threatened by Jesus and came against him in an attempt to undermine his authority. First, “the chief priests and the scribes with the elders came up and said to him, ‘Tell us by what authority you do these things, or who it is that gave you this authority” (Luke 20:1–2, ESV). After this, “they watched him and sent spies, who pretended to be sincere, that they might catch him in something he said, so as to deliver him up to the authority and jurisdiction of the governor” (Luke 20:20, ESV). These spies attempted to pit Jesus against the Roman authorities by asking him, “Is it lawful for us to give tribute to Caesar, or not?” (Luke 20:22, ESV). Finally, some from among the Sadducees attempted to gain an upper hand over Jesus by pitting him against the authority of Moses and the Holy Scriptures. If the resurrection is true, then how do you explain this text? This was their tactic. None of it worked as Jesus replied to their questions truthfully and winsomely. In Luke 20:39-40, we read, “Then some of the scribes answered, ‘Teacher, you have spoken well.’ For they no longer dared to ask him any question” (Luke 20:39–40, ESV).

Here in the text that is open before us today, it is finally Jesus who asks the questions. And as I have said before, I do believe it is important to see that Jesus’ questions have very much to do with the questions that were previously asked of him. In brief, those who came against Jesus questioned, One, the source of his authority. Two, they attempted to pit Jesus’ claimed authority against the governing authorities of this world to bring him into disfavor with them? Three, they attempted to pit Jesus’ claimed authority against the authority of Holy Scripture. Now, here in Luke 20:41-44, Jesus asks his opponents a question. And if they could only answer this one question correctly, then they would have the answer to all of the questions they had previously asked. I think you will see what I mean as we consider this small but mighty text together today.

Jesus’ Question

Let us now consider Jesus’ question. Really, he asks only one question, but it comes to us in three parts.  

Our text begins with the words, “But he said to them…” 

“Them” must refer to the scribes who were mentioned in verse 39, who will be mentioned again in verse 46. The scribes were considered expert interpreters of the Old Testament Scriptures. Now, when I say that Jesus spoke to the scribes, I do not mean to suggest that they were the only group present. I do believe that a great multitude stood around Jesus, including many of those who had questioned him previously. Jesus directed this question to the scribes in particular because they were regarded as expert interpreters of the Scriptures, and the question Jesus asks has to do with the interpretation of a very important text of Scripture, as we will soon see. So Jesus put this question to the scribes, but many others were there to witness this exchange and to be instructed by it.  

The first part of Jesus’ question is this: “How can they say that the Christ is David’s son” 

This was a commonly held view amongst the Jews in Jesus’ day. Most were looking forward to the arrival of the Christ, that is to say, the Messiah. “Christ” is the Greek translation of the Hebrew word “Messiah”, which means “one who is anointed” (see John 1:41; 4:25). The Old Testament Scriptures are very clear. They revealed that one day, an anointed King would come who would bring salvation to God’s people. And the Old Testament Scriptures are clear that this Anointed King would be a descendant of King David. This is spoken of in multiple passages in the Old Testament, but the central passage is 2 Samuel 7. There, we are told about the covenant God made with King David. Among other things, God gave this promise to King David: “When your days are fulfilled and you lie down with your fathers, I will raise up your offspring after you, who shall come from your body, and I will establish his kingdom. He shall build a house for my name, and I will establish the throne of his kingdom forever” (2 Samuel 7:12–13, ESV). When this text is considered carefully, it is clear that this promise was not fulfilled in David’s son, Solomon, but would be fulfilled by another, greater son, namely, the Messiah. And so the people knew that when the Christ or Messiah finally arrived, he would have to be a descendant of King David.

It should be clear to all that when Jesus asked the question, “How can they say that the Christ is David’s son?, he was not disagreeing with this idea. No doubt, Jesus agreed that the Messiah would be David’s son. He begins his question like this, not because he disagrees, but because he is about to demonstrate that there is more to the Messiah than mere fleshly descent from King David. Would the Messiah be David’s? Yes, of course! But Jesus is about to demonstrate that there is more to say about the Messiah.  

He demonstrates that there is more to the Messiah than fleshly descent from David by pointing to Psalm 110. Brothers and sisters, you should know that Psalm 110 is quoted or alluded to in the New Testament more than any other Old Testament text. That should tell you something about its importance. Psalm 110 is a very, very important passage as it pertains to the identity of the Messiah. 

Jesus introduces his question with the words,  “How can they say that the Christ is David’s son?”, but he did not end there. In the second portion of his question, he quotes Psalm 110 verse 1, saying, “For David himself says in the Book of Psalms, ‘The Lord said to my Lord, ‘Sit at my right hand, until I make your enemies your footstool’” (Luke 20:42–43, ESV). 

I want you to notice a few things about Psalm 110:1 and what Jesus has to say about it. 

First of all, this Psalm was written by King David. It’s original and inspired title is, A PSALM OF DAVID. And Jesus clearly believed that this Psalm was written by David, for he says in our text, “For David himself says in the Book of Psalms, ‘The Lord said to my Lord, ‘Sit at my right hand, until I make your enemies your footstool’” (Luke 20:42–43, ESV). 

Secondly, notice that King David mentions two “Lords” in this Psalm. The first “LORD” has the Hebrew word YHWH behind it. There is no mystery here. This is an obvious reference to the one true God—the God who created the heavens and the earth, who redeemed Isarel from Egyptian bondage and entered into covenant with Isarel in the days of Moses. The identity of the second “Lord” was a bit more mysterious. It has the Hebrew word Adonai behind it. This word is often used as a title for God, but it can be used to refer to human lords as well. The question was, who is this second  “Lord” (Adonai) of King David to whom the LORD (YHWH) speaks in this Psalm? Granted, this is no longer a mystery to us, for the proper interpretation of this Old Testament text has been clearly revealed by Christ and his Apostles and is now found in the New Testament. But it must have been a bit of a mystery to those who lived before the coming of the Christ. Who is this second Lord of King David to whom YHWH speaks? That is the question.

When I say that the meaning of this verse was a mystery before the arrival of the Christ, I do not mean to suggest that the true meaning was unknowable, for there are clues to its true meaning that could be easily observed even before Christ and his Apostles clarified the meaning of this text. .

For one, given that this Psalm was written by King David, the highest authority in Israel, it is clear that the second Lord (Adonai) of whom David speaks cannot refer to a human living during his reign. David the King would not have referred to anyone as Lord except for God and Christ, and that is the point, as we will soon see. Who had more authority than David? No one, except God and the Christ who would one day descend from him.  

Two, Psalm 110 must be interpreted in light of the covenant that YHWH made with David beforehand. In that covenant, God made a promise to David that he would have a son who would be greater than him, whose kingdom would have no end. This covenant promise should have been in the minds of all who read Psalm 110 even before Jesus was born. Those who wished to know the true meaning of Psalm 110 should have said, I wonder if this second Lord of David is in fact the greater son who was promised to him in 2 Samuel 7. In other words, I wonder if this is a reference to the  Messiah who is to come! In fact, if you were to read Jewish commentaries, some ancient and some modern, you would find that some Rabbis did interpret Psalm 110:1 as being about the Messiah. For those who are curious about this, John Gill quotes some of these Rabbis in his commentary on Matthew 22:44, which is a parallel passage to our text here in Luke 20:41-44. The point is this: This Psalm 110—this Psalm of David—must be interpreted with the promises that God made to David concerning a son who would have an everlasting kingdom in mind.  

Three, when you read the rest of Psalm 110, you see that this second Lord of King David—the Lord to whom YHWH speaks— is a great King who will one day rule and judge the nations.  We will look at Psalm 110 more closely in just a moment. For now, I am simply observing that interpreting Psalm 110 verse 1 as if it is about YHWH speaking to the Messiah, who is simultaneously the son and Lord of King David, is not at all a stretch. In fact, this interpretation is most reasonable and natural.  

The third thing to notice about Psalm 110 verse 1 and Jesus’ remarks about it is that, whatever others thought about the meaning of this verse, Jesus clearly thought and taught that it is about the Messiah. Listen to the words of Jesus again: “But he said to them, ‘How can they say that the Christ is David’s son? For David himself says in the Book of Psalms, ‘The Lord said to my Lord, ‘Sit at my right hand, until I make your enemies your footstool.’” Jesus then brings his question to a conclusion by saying, “David thus calls him Lord, so how is he his son?” (Luke 20:41–44, ESV). The words “him” and “he” in Luke 20:44 must refer back to “the Christ” mentioned in verse 41. So in brief, the question Jesus asked is this: In Psalm 110:1, King David calls the Christ or Messiah “Lord”, how then is the Christ his son? 

This is a very important question. I hope you understand the significance and weight of it. 

Do fathers typically call their sons “Lord”? No! A son may call his father Lord, but fathers do not refer to their sons as Lord, for fathers have authority over their sons. This is true of every father-son relationship, but it is especially true when the father is a King, as David was. So you can see that there is something unusual and even shocking going on here in Psalm 110:1, and Jesus drew attention to it. Again, the question is simply this: If it is true that the Messiah, the Anointed King of God’s Kingdom who was to come, would be the son of King David, why did King David call his son Lord?

The Implied Answer

Notice that Jesus did not provide an answer to the question. He asked the question and then he left it alone. The answer is implied, though, and it is not difficult to see. In brief, David called his son “Lord” because his son would be greater than him. The authority his son would possess would be much greater than his.  And so it was right for King David, the greatest of the Kings of Israel, and the King from whom all of the other Kings of Israel would descend, to call this Son, Lord. 

When Jesus drew attention to verse 1 of Psalm 110 and to the unusual features of this Messianic text, he was inviting the scribes, and all who listened in on his conversation with them, to go to Psalm 110 and to consider that weighty text anew and afresh. Who would the Messiah be, and what authority would he possess? And of course, everyone knew that Jesus was claiming to be the Messiah, the Son of David, who is also David’s Lord.    

The Answer To This Question Answers Other Questions

In the introduction to this sermon, I suggested that the answer to the question that Jesus asked the scribes would answer other questions, too, specifically, the questions that were previously put to him. Stated differently, I do believe that a proper interpretation of Psalm 110 functions like a key that unlocks many mysteries and answers many questions about the identity and authority of the Messiah. 

“The chief priests and the scribes with the elders came up and said to [Jesus], ‘Tell us by what authority you do these things, or who it is that gave you this authority” (Luke 20:1–2, ESV). Psalm 110 answers this question. If Jesus is the Messiah, who is David’s son and David’s Lord, then Psalm 110 reveals that his authority is from YHWH.  For it was YHWH who had spoken to him in the eternal Covenant of Redemption and at his assension, saying, “Sit at my right hand, until I make your enemies your footstool” (Psalm 110:1, ESV). It was YHWH who has sent “forth from Zion [his] mighty scepter.” And has decreed that he ”rule in the midst of [his] enemies!” (Psalm 110:2, ESV). By what authority did Jesus do these things? It was by God’s authority, for it was God the Father who, in eternity, decreed that the eternally begotten Son would become incarnate. Being born into the world as a son of Abraham and David, he would live a sinless life and die the death of a sinner for us and for our salvation. On the third day, he would rise. And after 40 days, he would ascend to heaven and, as the God man, he would sit down upon his throne at the Father’s right hand. By what authority did Christ do these things? It was by God’s authority, for it was God the Father who sent him, and he is the Son of God incarnate, the one who is anointed by God the Holy Spirit to do his work.  

A proper interpretation of Psalm 110 also helps to explain the answer Jesus gave to the spies who attempted to pit Jesus against the Roman authorities by asking, “Is it lawful for us to give tribute to Caesar, or not?” (Luke 20:22, ESV). What did Jesus say? “He said to them… ‘render to Caesar the things that are Caesar’s, and to God the things that are God’s” (Luke 20:25, ESV). In other words, for now, those in the kingdom of Christ will have to tolerate those who have worldly authority and give them their due, taxes to whom taxes are due, and respect to whom respect is due.  Psalm 110 reveals why this is so, for it teaches that the kingdom of Christ would come progressively. “The LORD says to my Lord: ‘Sit at my right hand, until I make your enemies your footstool’” (Psalm 110:1, ESV). So then, the Christ would first be seated on his heavenly throne, and after that his enemies would progressively be subdued. 

Paul speaks of this progression in 1 Corinthians 15:24-26, saying, “Then comes the end, when he delivers the kingdom to God the Father after destroying every rule and every authority and power. For he must reign until he has put all his enemies under his feet. The last enemy to be destroyed is death.” (1 Corinthians 15:24–26, ESV)

Psalm 110 reveals even more about this progression when it says that the Christ will, for a time, “Rule in the midst of [his] enemies!” (Psalm 110:2, ESV). Is that not what he is currently doing? He rules and reigns now, but his enemies are not yet fully and finally judged. And it is during this time—the time wherein the kingdom of the Messiah is inaugurated but not yet consummated— his “people… offer themselves freely on the day of [his] power, in holy garments…” (Psalm 110:3, ESV). Christ has enemies now, but he also has his people. They are those who have freely bowed the knee to him to confess him as Lord. They are those who trust in him and obey him. Christ the King does not force or coerce his people to “offer themselves” up to him. No, he makes the able and willing to come to him by his grace and by the regenerating work of the Holy Spirit as the word of Christ is preached. 

Psalm 110 also reveals that Christ is not only the King of God’s kingdom, but he is also the High Priest, for “The LORD has sworn [to him] and will not change his mind, [saying] “You are a priest forever after the order of Melchizedek” (Psalm 110:4, ESV). No wonder Christ cleansed the temple and taught within its courts. He is the priest of God’s end times temple—a temple, not made of stone, but of living stones built upon the foundation of Christ, the Apostles, and Prophets. 

When will it be that God’s people will no longer have to “render to Caesar the things that are Caesar’s”? When Christ returns to judge and to consummate his kingdom. It will be then that his enemies will be made his footstool (Psalm 110:1). It will be then that “he will shatter kings on the day of his wrath. He will execute judgment among the nations, filling them with corpses; he will shatter chiefs over the wide earth” (Psalm 110:5–6, ESV). 

Finally, some from among the Sadducees attempted to gain an upper hand over Jesus by pitting him against the authority of the Holy Scriptures. By pointing to this key text and raising questions about it, Jesus implied that, far from being at odds with the Scriptures, he was the fulfillment of them, being the very Christ and Lord of whom they spoke. 

Conclusion

As I have said, this passage is all about authority, authority, authority—the supreme authority of Christ the King. 

Is he your Lord and King? That is the question. 

To have him as Savior, you must have him as Lord and King, and Kings are to be obeyed. 

And what a marvelous King Jesus is. He is the King of kings and Lord of lords. All authority in heaven and earth has been given to him. Other kings may sit on earthly thrones, but he, having accomplished our redemption, is seated at the Father’s right hand in heaven, “far above all rule and authority and power and dominion, and above every name that is named, not only in this age but also in the one to come” (Ephesians 1:21, ESV).  There he will rule and reign until all his enemies are subdued under his feet. Then, he will judge the nations with a rod of iron. But to his people whom he has redeemed by his shed blood, he is gentle, kind, and compassionate. He provides for his people and protects them as he leads them into their eternal home—a home that he has prepared for them.

Dear friends, you must learn to think of Jesus as the greatest of all kings and as the King of the greatest of all kingdoms, for his power is supreme and his rule and reign will have no end. If you have not yet renounced your allegiance to sin, Satan, and his kingdom of darkness and bowed the knee to King Jesus instead, today is the day to do it. And if you have already pledged your allegiance to King Jesus, I urge, brothers and sisters, surrender to him more and more. Offer yourself freely to him in holy garments” (Psalm 110:3, ESV). Do this to the glory of Christ and for your good.

Scripture Reading: 1 Corinthians 6:18–7:5

“Flee from sexual immorality. Every other sin a person commits is outside the body, but the sexually immoral person sins against his own body. Or do you not know that your body is a temple of the Holy Spirit within you, whom you have from God? You are not your own, for you were bought with a price. So glorify God in your body. Now concerning the matters about which you wrote: ‘It is good for a man not to have sexual relations with a woman.’ But because of the temptation to sexual immorality, each man should have his own wife and each woman her own husband. The husband should give to his wife her conjugal rights, and likewise the wife to her husband. For the wife does not have authority over her own body, but the husband does. Likewise the husband does not have authority over his own body, but the wife does. Do not deprive one another, except perhaps by agreement for a limited time, that you may devote yourselves to prayer; but then come together again, so that Satan may not tempt you because of your lack of self-control.” (1 Corinthians 6:18–7:5, ESV)

Before we can understand what the sin of adultery is, we must first understand God’s design for sexual relations. In the beginning, God created the heavens and the earth. And the pinnacle of God’s earthly creation was man made in his image. As Genesis 1:27 says, “So God created man in his own image, in the image of God he created him; male and female he created them” (Genesis 1:27, ESV). And in the beginning, God also instituted marriage. As Genesis 2:24 says, “Therefore a man shall leave his father and his mother and hold fast to his wife, and they shall become one flesh” (Genesis 2:24, ESV). This one-flesh union is covenantal and spiritual. In the marriage covenant, two lives become one. But it is also physical. The sexual union consummates the covenantal marriage bond after it has been made. 

And this is where we must begin if we are to understand the seventh commandment, which is “Thou shalt not commit adultery.” God created sex, so it must be considered good. But like many other things, it is only good when enjoyed in a particular context. Wine is good, but it may be misused. Men and women do sin when they drink wine to the point of drunkenness. Money is good. But the love of money is a root of all kinds of evil. And so too, sex is good. But it may be misused, abused, and badly distorted. It is good when it is enjoyed by a man and woman bound together as one flesh in the covenant of marriage. 

When two who are unmarried engage in sexual relations, that is called fornication. Deuteronomy 22:28ff. speaks to the sin of fornication when it says, “If a man meets a virgin who is not betrothed, and seizes her and lies with her, and they are found, then the man who lay with her shall give to the father of the young woman fifty shekels of silver, and she shall be his wife, because he has violated her. He may not divorce her all his days” (Deuteronomy 22:28–29, ESV). Now, we are not under the law of Moses as a civil law code, but we may learn from this law even still. It is fornication that is described here, and not adultery, for neither the man nor the woman was betrothed or married. And the penalty, you will notice, was not death but a fine. 

The sin of fornication is serious. Sexual relations are to be reserved for marriage. But a more serious sin is the sin of adultery, wherein one who is married lies with someone who is not their spouse. That adultery is a more serious sin is made clear from the punishment prescribed under the law of Moses. Again, we are not under the law of Moses as a civil law code, but we may learn something about the seriousness of the sin of adultery from what it says—the adulterer and the adulteress were to be put to death. Deuteronomy 22:22 says, “If a man is found lying with the wife of another man, both of them shall die, the man who lay with the woman, and the woman. So you shall purge the evil from Israel” (Deuteronomy 22:22, ESV). Don’t mess with the sin of adultery, brothers and sisters. It is so very destructive. 

And if we were to go even further to discuss greater acts of sexual perversion, we would have to talk about the sins of homosexuality and bestiality. Concerning the sin of homosexuality, Leviticus 18:22 says, “You shall not lie with a male as with a woman; it is an abomination” (Leviticus 18:22, ESV). 

And the New Testament scriptures also speak against these sexual sins. Take, for example, 1 Corinthians 6:9, which says, “Or do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived: neither the sexually immoral, nor idolaters, nor adulterers, nor men who practice homosexuality, nor thieves, nor the greedy, nor drunkards, nor revilers, nor swindlers will inherit the kingdom of God. And such were some of you. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God” (1 Corinthians 6:9–11, ESV).

As I have said, to understand the seventh commandment and the sin of adultery, we must first understand God’s design for sexual relations. God created sex to be enjoyed by a man and a woman bound together for life in the covenant of marriage. All other sexual relations are a perversion of God’s design. Sexual immorality of all kinds is to be avoided, especially the sin of adultery, for when the sin of adultery is committed, the marriage covenant, which is a very sacred thing, is broken. 

Can the adulterer be forgiven? Yes, of course. And so too can the homosexual and the fornicator. Did you hear what Paul said to the Corinthians? After speaking of the sins of sexual immorality, adultery, and homosexuality (among other things), he said, “And such were some of you. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God” (1 Corinthians 6:11, ESV). “Such were some of you”, Paul said. And by this, he indicates that the Christians in Corinth were no longer these things, for they had turned from their sin and to Christ—they were washed, sanctified, and justified, through faith in Jesus Christ. 

You know, it is common for homosexuals and other sexually perverse people today to say, This is who I am. And there may be some truth to that. But look at what the Scriptures say. Who you are needs to change! God is calling you to turn from your sin and to Christ, for in Christ, there is cleansing, renewal, and the forgiveness of sins. Who would allow the liar, the thief, or the adulterer to excuse their sin by saying, This is who I am? Though I do not doubt that people have propensities towards these sins. And though it may be true that their deepest desires lead them in this sinful direction. And perhaps this is their way of life to the point that they can hardly distinguish between the sinful act and their very being. Even still, God calls sinners to turn from their sin and to believe upon Christ for the forgiveness of sin and for renewal, so that it may be said of them, “and such were… you… but you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God” (1 Corinthians 6:9–11, ESV).

The sin that is expressly forbidden in the seventh commandment is adultery. And adultery is forbidden because it is particularly damaging. Not only is it a perversion of God’s design for sexual relations, but it is also the breaking of the covenant of marriage. I do not need to describe to you the damage that the sin of adultery does to individual lives, families, and society. 

But as usual, our catechism helps us to see that the commandment is to be interpreted and applied broadly. Not only does the seventh commandment forbid the sin of adultery, it also requires “the preservation of our own and our neighbor’s chastity, in heart, speech, and behavior”, while forbidding “all unchaste thoughts, words, and actions.” The rest of the scriptures make it very clear that this is the proper interpretation and application of God’s moral law, “Thou shalt not commit adultery.”

Baptist Catechism 76 and 77

Not only does the seventh commandment forbid you from committing adultery, it requires that you seek to preserve your own and your neighbor’s chastity. Now there is an old-fashioned word — chastity. It should not be old-fashioned. It ought to still be on our minds and lips. To be chaste is to abstain from extramarital or premarital intercourse. The seventh commandment requires us to preserve our own chastity and also our neighbors. 

This means that men and women should be careful not to bring temptation to those around them. Being mindful of this will affect the way that you dress and the way that you talk.

This also means that husbands and wives should be generous with one another as it pertains to conjugal rights, for this does help to guard against temptation. You may read 1 Corinthians 6:18-7:5 again to see what I mean. Husbands and wives are to serve one another in this way. 

And notice also how our catechism applies the seventh commandment to the heart, and not merely to our words and actions, saying, “The seventh commandment requireth the preservation of our own and our neighbor’s chastity, in heart, speech, and behavior”, and again, “The seventh commandment forbideth all unchaste thoughts, words, and actions.”

God’s commands are always to be applied to the heart, friends. You should know this by now. And this is why Jesus said, “You have heard that it was said, ‘You shall not commit adultery.’ But I say to you that everyone who looks at a woman with lustful intent has already committed adultery with her in his heart.”

Jesus was not saying something new here. Instead, he was giving the proper interpretation of the seventh commandment. God’s law was always meant to be applied to the heart. Remember the summary of the law is to love God with all our being and to love our neighbor as ourselves. Here, Christ is simply saying that the seventh commandment is to be kept from the heart. This was always the intent. 

And please don’t misunderstand his words. He is not saying that lust and adultery are the same thing. They are not. Adultery is worse because it is the sin of lust full-grown. Jesus is simply teaching that lust is adultery in the heart. Lust is adultery in seed form. Root it out, brothers and sisters, for lust is a sin. And root out the sin of lust, before it is fully grown, leading to the act of sexual immorality and even adultery.

Conclusion 

“Flee from sexual immorality. Every other sin a person commits is outside the body, but the sexually immoral person sins against his own body. Or do you not know that your body is a temple of the Holy Spirit within you, whom you have from God? You are not your own, for you were bought with a price. So glorify God in your body.” (1 Corinthians 6:18–20, ESV)
