Preaching Old Testament law through the gospel: A Step-by-Step Guide
Short answer: In Matthew 5:17, Jesus declares that he did not come to destroy the law or the prophets but to fulfill them. This statement sets the tone for the rest of the Sermon on the Mount, where Jesus reinterprets and elevates the moral teachings found in the Old Testament. The passage emphasizes continuity between the law as given by Moses and the new teaching that Jesus brings through his life and ministry.
The Setting: A Mountain with a Crowd
Jesus begins his public teaching on a mountain, where he addresses a crowd of people. This location is significant because it recalls Moses receiving the law at Mount Sinai (Exodus 19), suggesting that Jesus' teachings are as authoritative and foundational as those given to Israel long ago. The movement from the Sea of Galilee to the mountain indicates a transition from ordinary life into spiritual instruction, setting up a sacred space for divine revelation.
The presence of both multitudes and disciples suggests an audience with varying levels of understanding. While the crowd may have come out of curiosity or expectation, the disciples are specifically called to be taught by Jesus. This distinction is important because the Sermon on the Mount is not just a moral lecture but a call to discipleship that requires deeper engagement with the teachings.
The structure of the passage begins with Jesus seeing the multitudes and going up onto the mountain (Matthew 5:1). This act of ascending the hill is symbolic, echoing other biblical moments where spiritual insight was revealed from elevated places. The setting also highlights the contrast between Jesus' teaching and the law given by Moses at Sinai.
The Sermon on the Mount begins in a context that echoes Israel's history while introducing new insights. By choosing to teach from a mountain, Jesus positions himself as both a continuation of God's revelation through the law and a fulfillment of it. This choice underscores his unique role as the one who brings fullness to what was previously only foreshadowed.
The Teaching: A New Interpretation of Old Truths
Jesus' declaration in Matthew 5:17 marks a shift from mere adherence to the law as written to an internalization and embodiment of its spirit. He does not come to abolish, but to complete what was previously incomplete. This is crucial because it implies that the law's purpose was always pointing toward something greater, something Jesus would bring through his life, death, and resurrection.
The phrase "fulfill" (Greek: πληρῶσαι) carries deep theological weight. It suggests not just a continuation of the law but an actualization of its deepest intentions. This is different from upholding or preserving it as was done by the Pharisees. Jesus' approach to the law goes beyond outward compliance and calls for inner transformation.
Jesus' teaching in this passage moves the focus from legalistic observance to a relationship with God that shapes every aspect of life. The Beatitudes that follow (Matthew 5:3-12) illustrate how righteousness is not about following rules but living in alignment with God's character. This redefines what it means to be truly righteous.
By stating his intent to fulfill the law, Jesus introduces a new dimension to its application. He does not merely affirm the commandments but shows their full meaning and purpose through his own example. His life becomes the standard by which all laws are measured, shifting the emphasis from external performance to internal alignment with God.
The Wording: A Declaration of Purpose
The wording in Matthew 5:17 is precise and deliberate. Jesus says, "Don't think that I came to destroy the law or the prophets. I didn't come to destroy, but to fulfill." This direct statement rejects any interpretation that might suggest his coming would abolish previous teachings. Instead, it affirms continuity with them while also showing how they are brought to their full meaning.
Jesus' use of "Don't think" is a call for careful reflection and understanding. He addresses the possibility that some may have misinterpreted or misunderstood the nature of his mission. This warning highlights the importance of listening not only to what Jesus says but also to why he says it, emphasizing clarity in theological interpretation.
The term "fulfill" (πληρῶσαι) is key here. It implies completion rather than replacement, showing that the law was never meant to be an end in itself but a preparation for something greater, something Jesus would bring through his life and ministry. This word choice avoids any notion of contradiction between Jesus' teaching and the Old Testament.
Jesus' statement also sets up the structure of the Sermon on the Mount as one that expands upon, rather than abandons, the law. It indicates that what was previously given in partial form will now be fully revealed through his teachings. This passage thus becomes a bridge between the old covenant and the new.
The Revelation: Jesus as the Fulfillment of God's Plan
Jesus' declaration that he came to fulfill the law reveals his unique role in the divine plan. He is not merely a reformer or teacher but one who brings full realization to all that was previously foreshadowed and promised. This revelation positions Jesus as both the fulfillment of God's covenant with Israel and the mediator of a new covenant.
The passage also highlights the continuity between Jesus' teachings and those found in the Old Testament. While he introduces new insights, he does not discard what came before. Instead, his teachings expand on the moral and spiritual truths that were already present but not fully understood or lived out by previous generations.
Jesus' mission to fulfill the law also includes a call for deeper righteousness than was seen among the scribes and Pharisees (Matthew 5:20). This suggests that external compliance with legalistic rules is insufficient. True righteousness must come from within, shaped by relationship with God rather than mere obedience to outward regulations.
By fulfilling the law, Jesus also demonstrates his authority as one who can interpret its true meaning. His teachings go beyond what was previously written or spoken, showing that he has not only a full understanding of the law but also the power to bring it to completion in human lives.
The Theology: A New Covenant and a Call to Discipleship
The theology behind Jesus' statement in Matthew 5:17 is deeply tied to the idea of a new covenant. He does not come to replace the law but to bring it to its full expression through his life, death, and resurrection. This sets up the foundation for a relationship with God that goes beyond mere legalistic obedience.
Jesus' fulfillment of the law also points toward the coming of the Holy Spirit, who would guide believers into all truth (John 16:13). The Sermon on the Mount is not just an ethical teaching but a glimpse of what life under the new covenant will look like, a life characterized by righteousness that flows from within.
This passage also challenges the notion that following Jesus means abandoning Jewish heritage or identity. Instead, it shows that true discipleship involves embracing and living out the law in its fullness through faith in Christ. This includes not only moral behavior but also a transformed heart and mind aligned with God's will.
The call to fulfill the law is thus a theological invitation to enter into a deeper relationship with God, one that transforms every aspect of life. It shows that righteousness is not about following rules for their own sake but living in alignment with God's character through faith in Jesus.
The Implications: Living in Light of the Law's Fulfillment
Jesus' declaration to fulfill rather than destroy the law has profound implications for how followers of Christ should live. It calls for a deeper understanding of the moral and spiritual principles behind the commandments, not just their outward observance. This shifts the focus from legalism to a lifestyle that reflects God's character.
The Sermon on the Mount, which follows Jesus' statement in Matthew 5:17, provides practical examples of how this righteousness looks in daily life. The Beatitudes and other teachings show that true obedience is rooted in love for God and neighbor, not just external compliance with rules or rituals.
This passage also invites believers to see the law as a reflection of God's character rather than a burden to be avoided. Jesus' fulfillment of it shows that the law was never meant to restrict but to reveal what is already present in God's heart for humanity, love, mercy, and justice.
Living in light of this understanding means embracing a life transformed by faith in Christ. It involves not only following moral guidelines but also cultivating inner righteousness that flows from relationship with God. This holistic approach to living out the law through Jesus' example is central to Christian discipleship.

Biblical fidelity check
Matthew 5:17 must be read carefully, as it carries significant theological weight and can easily be misunderstood or misapplied. The key interpretive risk lies in interpreting this passage as a call to abolish the law rather than fulfill it. Some have mistakenly viewed Jesus' teachings as a rejection of Old Testament morality, but this is not supported by the text itself. What stays central is that Jesus does not come to destroy the moral framework given through Moses and the prophets but brings its full meaning into realization through his life, death, and resurrection. His fulfillment of the law does not mean eliminating it but showing how every commandment was pointing toward a deeper relationship with God, which only he can fully bring about. Understanding this helps avoid misinterpreting Jesus' teachings as contradictory to the Old Testament while recognizing that his message completes what was previously incomplete.
