Matthew 5:17-20: Did Jesus Abolish or Fulfill the Law?
Short answer: In Matthew 5:17-20, Jesus says He did not come to destroy the law or the prophets but to fulfill them. This means He is the goal and completion of everything the law pointed toward. He did not cancel God's moral commands, but He fulfilled the ceremonial and prophetic patterns by His life, death, and resurrection. The law still reveals God's character and our need for a Savior, but it was never able to make us righteous. Christ alone does that for everyone who believes. Believers are not freed to sin but are freed from the law's condemnation. Romans 3:31 says, "Do we then nullify the law through faith? May it never be! No, we establish the law."
What Jesus Meant by "Destroy" and "Fulfill"
He opened his mouth and taught them, saying, "Don't think that I came to destroy the law or the prophets. I didn't come to destroy, but to fulfill." He is speaking to a Jewish audience who knew the law as God's greatest gift. To destroy meant to loosen, dismantle, or teach others to disregard God's commands. Jesus was not a rebel against Scripture. He was not starting a new religion that ignored the Old Testament. Instead, He was claiming to be the one the whole Old Testament pointed to. Every sacrifice, every prophet, and every command found its yes in Him. He did not come to set aside the Bible of His day but to bring it to its intended goal.
The word fulfill carries the sense of filling up or completing. Jesus did not merely obey the law perfectly, though He did. He also filled the prophetic writings with meaning by embodying them. The law said to love God and neighbor; Jesus did that without failure. The prophets spoke of a coming servant, a suffering king, and a new covenant; Jesus was that servant and king. When He read Isaiah in the synagogue, He said the Scripture was fulfilled in their hearing. So the law and prophets are not discarded. They are completed in a person, and that person is Jesus.
Many people today assume that if something is fulfilled, it is finished and useless. That is not how Jesus treats Scripture. Fulfillment does not mean erasure. A seed is fulfilled when it becomes a tree, but the tree does not mock the seed. A promise is fulfilled when it is kept, but the keeping does not despise the promise. In the same way, the Old Testament remains God's Word. It still teaches us about God's holiness, human sin, and the need for atonement. It still gives wisdom and warns against evil. What has changed is that we now read it in light of Christ, who is the key to its meaning.
This is why Jesus immediately goes on to talk about the commandments. He does not say the commands are irrelevant. He says our righteousness must exceed that of the scribes and Pharisees. That would be impossible if He meant we could ignore God's moral will. Instead, He intensifies the commands, showing that anger is murder's root and lust is adultery's root. The law was never just about external actions. It always aimed at the heart. Jesus did not lower the standard; He revealed its true depth and then fulfilled it on our behalf.
Why the Law Still Matters for Christians
Some Christians speak as if the Old Testament law is a dusty relic with no value. But Paul does not speak that way. In Romans 3:31 he asks, "Do we then nullify the law through faith? May it never be! No, we establish the law." Faith does not make the law pointless. It establishes it by showing that the law's demand for perfect righteousness is met in Christ, not in our own effort. The law still tells us what love looks like. The Ten Commandments still describe a life that honors God and protects neighbors. We do not obey them to earn salvation, but we obey them because we have been saved.
The law also still serves to expose sin. When we read that we should not covet, we feel our greed. When we read that we should love our enemies, we feel our resentment. The law acts like a mirror, showing us the dirt on our faces. It cannot wash us, but it can send us to the one who can. Galatians 3:24-25 says, "So that the law has become our tutor to bring us to Christ, that we might be justified by faith." The law's role as tutor is not to make us righteous but to lead us to the righteous one.
Yet we must be careful. The law was given to Israel as a covenant with civil, ceremonial, and moral dimensions. Some parts, like the sacrifices and dietary rules, were shadows pointing to Christ. Hebrews 10:1-10 says the law had "a shadow of the good to come, not the very image of the things" and could never make worshipers perfect. Those shadows have done their work. We no longer sacrifice animals or keep the temple calendar. But the moral heart of the law, summed up in love for God and neighbor, remains. Jesus did not abolish that; He embodied it and writes it on our hearts by the Spirit.
So the Christian reads the law with gratitude. It shows us God's character. It shows us our need. It shows us the shape of love. But it never becomes our savior. We do not stand before God on the basis of our law-keeping. We stand on the basis of Christ's perfect life, atoning death, and victorious resurrection. The law is good, but it is not the gospel. It is a map that leads to the cross, and once we arrive at the cross, we do not throw the map away. We understand it better than ever.
Christ as the Fulfillment of the Law for Righteousness
Romans 10:4 says, "For Christ is the fulfillment of the law for righteousness to everyone who believes." This is the heart of the matter. The law demanded righteousness, but it could not produce it in sinful people. Christ came and became righteousness for us. He obeyed the law perfectly, loving God with all His heart and His neighbor as Himself. He then died the death the law demanded for lawbreakers. When we believe, His righteousness is credited to us. The law's demand is satisfied, not by our performance, but by His. This is why the gospel is good news and not just a new set of rules.
Notice the phrase "to everyone who believes." The fulfillment of the law is not automatic for all people. It is for those who trust in Christ. The law still condemns those who reject Him, because they remain in their sins. But for the believer, there is no condemnation. The law cannot accuse us because its penalty has been paid and its requirement has been met in Christ. This does not mean the law was bad. Paul says the law is holy, righteous, and good. The problem was never the law. The problem was our flesh, which was too weak to keep it. God did what the law could not do by sending His Son.
Romans 8:3-4 explains this: "For what the law couldn't do, in that it was weak through the flesh, God did, sending his own Son in the likeness of sinful flesh and for sin, he condemned sin in the flesh." God did not lower the law's standard. He condemned sin in the flesh of Jesus, who bore our penalty. As a result, the righteous requirement of the law is fulfilled in us, not by our own strength, but by the Spirit who lives in us. We now walk according to the Spirit, not according to the flesh. This is not lawlessness. It is a new kind of obedience, one that flows from a changed heart.
So when Jesus says He came to fulfill the law, He is not just talking about His teaching. He is talking about His entire mission. He is the true Israel who succeeded where Israel failed. He is the true temple where God meets His people. He is the true sacrifice that takes away sin. He is the true prophet who speaks God's final word. He is the true king who reigns in righteousness. Every line of the Old Testament finds its yes in Him. To read the law without Christ is to read a story with no ending. To read it with Christ is to see the ending was there all along, hidden in promises and shadows.
How Believers Relate to the Law Today
Christians often ask whether they are supposed to keep the Ten Commandments. The answer is yes, but not as a way to earn favor with God. We keep them because we love the God who saved us. We do not keep them to become His children; we keep them because we are His children. The commands against idolatry, murder, theft, and lying still reflect God's holy character. They still promote human flourishing. They still diagnose our sin. But they no longer define our standing before God. Our standing is in Christ, and it is secure. This distinction is crucial, because confusing law and gospel leads either to pride or despair.
The New Testament applies the law's moral teaching to believers repeatedly. Paul tells children to obey parents, which is the fifth commandment. He tells believers to love one another, which fulfills the law. He quotes the command against coveting to explain indwelling sin. So the law is not abandoned as a guide for Christian living. It is reappropriated through Christ and the Spirit. We read it as those who have already been justified, not as those trying to be justified. This changes everything. Obedience becomes a joyful response rather than a fearful attempt to appease God. We obey because we are loved, not to be loved.
At the same time, we must not impose the entire Mosaic covenant on believers as if Christ had not come. The book of Hebrews makes clear that the old covenant has been made obsolete because the new covenant has arrived. The temple sacrifices, the priesthood, and the ceremonial laws were shadows that pointed to Jesus. Now that the reality has come, we do not go back to shadows. We do not need to keep dietary laws or festival days as a means of righteousness. Colossians tells us these were a shadow of things to come, but the substance belongs to Christ. We are free from the law's ceremonial demands, but we are not free to sin.
This freedom is not a license for the flesh. Paul asks in Romans 6 whether we should sin so grace may abound, and his answer is emphatic: may it never be. The grace that saves us also teaches us to say no to ungodliness. The Spirit produces love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control. Against such things there is no law. So the Christian life is not lawless, but it is also not law-driven. It is Spirit-driven. The law shows us the goal, Christ achieves the goal, and the Spirit empowers us to walk in it. This is the fulfilled life Jesus came to give.
The Sermon on the Mount and the Greater Righteousness
Matthew 5:20 says, "For I tell you that unless your righteousness exceeds that of the scribes and Pharisees, there is no way you will enter into the Kingdom of Heaven." This sounds impossible. The scribes and Pharisees were the most religious people of their day. They fasted, prayed, tithed, and memorized Scripture. If their righteousness was not enough, whose is? The answer is that no one's righteousness is enough on its own. The righteousness that exceeds theirs is not a matter of doing more religious deeds. It is the righteousness of Christ received by faith. Jesus is not calling us to try harder in our own strength. He is exposing our need and pointing us to Himself.
But Jesus does not stop at our need. He also calls us to a deeper obedience. In the rest of the Sermon on the Mount, He shows what that obedience looks like. It is not just avoiding murder but dealing with anger. It is not just avoiding adultery but guarding our eyes. It is not just making oaths but speaking truth so simply that oaths are unnecessary. It is not just loving those who love us but loving our enemies. This is a righteousness that goes to the heart. It cannot be manufactured by rule-keeping. It comes from a heart transformed by God. The law says, do not. The gospel says, become. And the Spirit makes us become.
So the Sermon on the Mount is not a new law that we must keep to be saved. It is a description of life in the kingdom. It shows what a citizen of heaven looks like. And it shows us how far short we fall. That is intentional. Jesus is not giving us a ladder to climb. He is giving us a mirror to see our need, and then He offers Himself as the Savior. The one who preached the sermon is the one who fulfilled it. He is the poor in spirit, the meek, the merciful, the pure in heart. He is the peacemaker. He is the one persecuted for righteousness. And He gives His Spirit to make us like Him.
When we understand this, the law no longer terrifies us. It challenges us, it guides us, and it sometimes convicts us, but it does not condemn us. There is therefore now no condemnation for those who are in Christ Jesus. The law's curse has been lifted. Its demand has been met. Its purpose has been fulfilled. We are free to obey from the heart, not to earn anything, but because everything has been earned for us. This is the glorious exchange: Christ takes our sin, and we receive His righteousness. The law is established, and we are saved. That is the message of Matthew 5:17-20.
Common Misunderstandings of This Passage
One common misunderstanding is that Jesus came to abolish the Old Testament and replace it with a new set of rules. This view sees the God of the Old Testament as wrathful and the God of the New as loving. But Jesus explicitly denies this when He says He did not come to destroy the law or the prophets. The God of the Old Testament is the same as the God of the New. The law was never a means of salvation by works. It was always a covenant of grace, given to a people already redeemed from Egypt. The commands were a response to redemption, not a way to earn it. So the Old Testament is not a failed experiment. It is the foundation of the gospel.
Another misunderstanding is that since Christ fulfilled the law, Christians have no obligation to any commandments at all. This view turns grace into license. Paul rejects it firmly in Romans 6. He asks, as Romans 6:1-2 says, "What shall we say then? Shall we continue in sin, that grace may abound? May it never be!" The believer has died to sin and cannot live in it any longer. The moral law remains a guide for holy living. We are not under law as a covenant of condemnation, but we are under Christ as Lord. To follow Him is to keep His commandments. He said, if you love me, you will keep my commandments. Grace does not cancel obedience; it enables it.
A third misunderstanding is that the law is only for Jews and has no relevance to Gentiles. But Paul says in Romans 3:31 that faith establishes the law. He also says that Gentiles who do not have the law show that the work of the law is written on their hearts. The moral law reflects God's universal character and applies to all people. The ceremonial law was specific to Israel and pointed to Christ, and it is fulfilled in Him. But the call to love God and neighbor is for everyone. So Gentile believers do not need to become Jews to follow Jesus, but they do need to live in a way that pleases Him. The law's moral core remains relevant for all believers.
A fourth misunderstanding is that we can divide the law into neat categories and ignore the ones we find inconvenient. Jesus did not give us that option. He said not one jot or tittle would pass from the law until all is accomplished. He also said that whoever relaxes one of the least of these commandments and teaches others to do the same will be called least in the kingdom. This should make us humble. We cannot pick and choose which commands we like. We must read all of Scripture through Christ and allow the Spirit to apply it to our lives. The law is not a buffet. It is God's Word, and it deserves our attention and obedience as those who have been transformed by grace.
Biblical fidelity check
Matthew 5:17-20 clearly establishes that Jesus did not come to destroy the law or the prophets. He came to fulfill them. It also establishes that the law will not pass away until all is accomplished, and that our righteousness must exceed that of the scribes and Pharisees. What this passage does not establish is that Christians are saved by keeping the law. Jesus is not telling His hearers to earn their way into the kingdom by doing more good works. He is exposing their need for a righteousness they cannot produce and pointing to Himself as the one who fulfills the law on their behalf. The passage also does not establish that the ceremonial and civil laws of the old covenant continue unchanged. Hebrews makes clear that those were shadows pointing to Christ, and now that He has come, they are fulfilled and no longer binding in their old form.
A common misreading of this passage is that Jesus is teaching salvation by works, or that He is giving a new law that we must keep perfectly to be saved. That misreading is wrong because it contradicts the rest of the New Testament, which clearly teaches that we are justified by faith and not by works of the law. Romans 10:4 says that Christ is the fulfillment of the law for righteousness to everyone who believes. If righteousness came through the law, then Christ died for nothing. So when Jesus says our righteousness must exceed that of the Pharisees, He is not calling us to a stricter form of self-righteousness. He is calling us to Himself, the one who is our righteousness. The law's role is to lead us to Him, and in Him we are complete.
Other passages that speak to Matthew 5:17-20
The teaching of Jesus in Matthew 5:17-20 connects to several other passages that help us understand how the law and the gospel relate. In the Beatitudes, Jesus describes the character of those who belong to His kingdom, showing that true righteousness is a matter of the heart. Galatians 1 and Galatians 2:20 explain how Paul defended the gospel of grace against those who wanted to add law-keeping to faith, insisting that we are justified by faith in Christ alone. Galatians 3:28 reminds us that in Christ all believers are one, regardless of ethnic or social background, because our standing is in Him.

Frequently asked questions
Did Jesus abolish the Old Testament law?
No. Jesus explicitly said He did not come to destroy the law or the prophets but to fulfill them. This means He is the goal and completion of the law. He did not cancel the moral commands, but He fulfilled the ceremonial and prophetic patterns by His life, death, and resurrection. The law still reveals God's character and our need for a Savior, but it was never able to make us righteous. Christ alone does that for everyone who believes. Believers are not freed to sin but are freed from the law's condemnation. The law remains good and useful for teaching, rebuking, correcting, and training in righteousness.
What does it mean that Christ fulfilled the law?
When we say Christ fulfilled the law, we mean He perfectly obeyed all its commands, bore its curse for our disobedience, and completed all the Old Testament shadows and prophecies. He is the true temple, sacrifice, priest, and king. He did what Israel and all humanity failed to do. As a result, His righteousness is credited to everyone who believes. We are not saved by our law-keeping but by His. The law's demand for perfection is satisfied in Him. This does not make the law irrelevant; it establishes it as a witness to Christ and a guide for grateful living.
Are Christians still supposed to obey the Ten Commandments?
Yes, but not as a means of earning salvation. The Ten Commandments reflect God's holy and unchanging character. They still show us how to love God and neighbor. We obey them because we have been saved, not to become saved. Our obedience flows from gratitude and the work of the Spirit in our hearts. The moral law remains a guide for Christian living, but it does not define our standing before God. Our standing is in Christ, who fulfilled the law for us. We are free from its condemnation but called to live in a way that pleases God.
