The sermon opens in Matthew 5:17-20, where Jesus declares that he has not come to abolish the Law or the Prophets but to fulfill them. To set the stage, the sermon reaches back into Israel's history: when Rehoboam refuses his people's plea to lighten the heavy yoke his father Solomon had placed on them, the nation fractures, and ten of the twelve tribes revolt. Centuries later, in the intertestamental period, the Jewish people undergo their own crisis over "yoke" and burden, though of a different kind. Following a religious revival, the scribes and Pharisees respond to national soul-searching by cataloguing and expanding God's law into thousands of detailed rules, believing that perfect law-keeping is the path to earning God's favor and blessing. This is Phariseism: scribes explain and expand the law, Pharisees strive to practice it flawlessly, all in hope of winning divine approval. But the harder they try, the more they fail, and the sermon exposes this as an open secret even among the top-ranking Pharisees — none of them can keep the law perfectly. Rather than abandon the project, the religious establishment maintains the appearance of success while privately failing, and ordinary Jews, seeing only the polished facade, keep trying and failing themselves, hoping tomorrow will be different. Some even try to solve the problem by softening the scribes' explanations of the law, but this fails because the difficulty lies in the law itself, not its interpretation. Others turn to Jeremiah 31:31 and its promise of a new covenant, hoping God will send a servant with authority to replace the old, harder covenant with an easier one.

Into this expectation Jesus arrives, teaching with an authority unlike the scribes, who could only quote earlier commentators. His message of grace, mourning over sin, and meekness sounds like a rejection of Phariseism, feeding the hope that he might be the promised one who would loosen the law's demands. It is against this backdrop that his declaration in verse 17 lands as a shock: he insists that not the smallest stroke of the Law and the Prophets — the entire Old Testament, the Tanakh of Torah, Nevi'im, and Ketuvim — will pass away, because the word of God is eternal and always accomplishes what it purposes. The sermon summarizes Jesus' teaching in this section in four words: the law shall stand. Its blessings and curses remain fully in force. Jesus then intensifies the demand rather than relaxing it, declaring that unless the disciples' righteousness exceeds that of the scribes and Pharisees — the most visibly disciplined law-keepers of the day — they cannot enter the kingdom of heaven. This closes off any hope that Jesus offers an easier covenant of relaxed rules.

Yet the same Jesus who upholds the law without exception is also the one who calls sinners to himself, promising forgiveness to those who repent and admit they cannot keep the law. The sermon names this second thread in another four words: sinners shall be blessed. The tension between "the law shall stand" and "sinners shall be blessed" resolves in the single hidden word of verse 17: fulfilled. The Old Testament is likened to a hundred-piece puzzle missing one piece — the Messiah — promised from Genesis onward, through the covering God provides for Adam and Eve, through Abraham, Moses, David, the Psalms, and Isaiah's suffering servant. The law itself was never given on the assumption that God's people would keep it perfectly; its sacrificial, purification, and priestly provisions already point beyond themselves to a needed substitute, since an animal's death, ceremonial washing, and sinful priests can never truly satisfy or cleanse. Jesus fulfills all of it: as the true Lamb of God he bears the sin the sacrifices could only symbolize, he purifies hearts by the Spirit rather than water, and he serves forever as the sinless great high priest. The sermon draws out three purposes of the law — to expose human sin and helplessness, to direct hope toward its coming fulfillment, and to reveal what a holy God requires and loves — and insists that believers now obey not out of fear of condemnation but out of gratitude, having already been freely forgiven. Because Jesus alone kept the law perfectly and earned its blessings, he can give those blessings away to all who come to him, changing the terms of the covenant not by erasing it but by fulfilling it. The sermon closes with a call to repentance and hope placed in Christ, since the law condemns everyone, but Jesus can save anyone.
