Galatians Overview: What's the Point of all the Bible's Laws?

About This Episode

Paul has argued that circumcision, along with other markers of Jewish identity, are not necessary to signal membership in the Christian community. But if that's the case, why is so much of our Bible full of laws and why did Jesus say he didn't come to abolish any of them if Paul is saying we don't need to follow them? Seth and David attempt to answer why we have so many Old Testament laws and why Paul's answer is the best news we could hope for.

A Galatians Overview on Faith, Freedom, and the Purpose of God's Commands

Show Notes

David Bowden and Seth Stewart continue their walk through the Book of Galatians, tackling one of the most persistent questions Christians face when reading the Old Testament: if we are saved by faith in Jesus, why did God give all those laws in the first place? Building on the previous episode's exploration of justification by faith, this conversation unpacks how the Apostle Paul addresses the purpose and ultimate fulfillment of the law in light of the Gospel.

Why Then the Law?

In Galatians 3:19, Paul asks the question his opponents were likely thinking: "Why then the law?" If circumcision and kosher eating don't identify us as members of God's family, and if trusting Jesus is all that's needed, what was the point of 613 commands given over centuries? The concern behind this question was real. Paul's opponents suspected he was saying the law contradicted God's promises, that something was fundamentally broken in Scripture itself. How could Jesus make the law obsolete if God himself had given it?

Paul's answer is direct. The law "was added because of transgressions until the offspring should come to whom the promise had been made." In other words, the law was never intended to save anyone. It was a signpost pointing forward to Jesus the Messiah. Just as circumcision was marked on the reproductive organs of Israelite men to anticipate a singular offspring who would bless all nations, the entire legal code was designed to shape and guide God's people toward the one who was coming. The law functioned as a constraint on behavior while simultaneously directing Israel's hope toward the promised son of Abraham who would unite all God's people by faith.

The Law as a Guardian for an Immature Heir

Paul compares God's relationship with his people to a child who stands to inherit a massive estate. A four-year-old heir cannot be trusted with a billion dollars. He needs training, discipline, and formation. He must learn responsibility, wisdom, and character before he can steward such wealth. Until then, a guardian or trustee manages his life, sets boundaries, and prepares him for the day when he will take full possession of his inheritance.

The law functioned like this trustee. It was never designed to create members of God's family but to guide people who were already part of that family so they could be ready to inherit the worldwide Kingdom of God. The commands were meant to transform Israel, to shape them into the kind of people who could steward such a great blessing and share it with the world. However, there was a problem. No one could keep the law. Israel failed, faced exile, and remained in need of redemption. The trustee was good, but the child was too unruly to graduate.

Jesus, the Obedient Brother Who Inherited Everything

When the fullness of time came, God sent forth his Son. Jesus was not another trustee. He was a brother, born of a woman, born under the law. He lived as an Israelite, submitted to the same guardian that had shaped his people for centuries, and did what no one else could do. Jesus obeyed the law perfectly. He matured. He was ready to inherit the estate.

Because Jesus succeeded where Israel failed, he received the inheritance. "All authority in heaven and earth has been given to me," he declared (Matthew 28:18). And in a stunning act of grace, Jesus adopted all who trust in him as his brothers and sisters, inviting them to rule the estate alongside him. Redemption was necessary precisely because the law could not save. Only a redeemer who could pay the debt and absorb the curse could set the heirs free. Jesus became a curse for us, hanging on a tree, so that in him the blessing of Abraham might come to all nations and so that we might receive the promised Spirit through faith (Galatians 3:13-14).

Slavery and Freedom: The Allegory of Hagar and Sarah

Paul presses his argument by drawing on the story of Hagar and Sarah from Genesis. He acknowledges that this is allegorical, a creative reading of the Old Testament to make a theological point. Hagar, the slave woman, bore a son according to the flesh, the product of Abraham's impatient effort to produce an heir on his own. Sarah, the free woman, bore a son according to promise, the result of trusting God's word even when it seemed impossible.

Paul aligns the law given at Mount Sinai with Hagar and the present Jerusalem, suggesting they bear children for slavery. But the Jerusalem above, the heavenly city, is free, and those who trust Jesus are children of Sarah, children of promise. The point is sharp: God's family was never formed through human effort or legal compliance but through the freedom of believing God's promises. Trying to earn membership in God's family through law-keeping is not liberation; it is a return to slavery.

Walking by the Spirit to Fulfill the Law

If faith frees us from the law, won't we just go off the rails? This is the obvious objection, and Paul addresses it head-on. He writes, "Walk by the Spirit, and you will not gratify the desires of the flesh" (Galatians 5:16). The entire law, he argues, is fulfilled in a single command: "Love your neighbor as yourself" (Leviticus 19:18). The way to truly obey the law is not through anxious rule-keeping but through being filled with the Spirit of Jesus.

The Holy Spirit, the very author of the law, now dwells inside those who trust Jesus. The law was external, a slave master constraining behavior from the outside. But sons and daughters are free. The Spirit increases that freedom by placing inside believers the desire and power to live as the law always intended. The fruit of the Spirit—love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control—represents what the law was always after. And against such things, Paul says, there is no law. There is no limit. The Spirit enables believers to obey without constraint, not as slaves but as heirs.

The Greater Righteousness of Jesus

Jesus himself made clear that his followers must exceed the righteousness of the Pharisees (Matthew 5:20). The law was not the ceiling of God's expectations; it was the floor. When Jesus fulfilled the law, he did not shrink obedience but expanded it. "You have heard it said, 'Do not murder,' but I say do not even be angry. You have heard it said, 'Do not commit adultery,' but I say do not even lust." The commands become deeper, reaching into motive and character, not just behavior.

This is why the Spirit is essential. The ratcheted-up expectations of Jesus would crush anyone trying to obey in their own strength. But the good news is that Jesus also ratcheted up the blessing. He gives not just a command but the very Spirit by which he obeyed, empowering believers to live the bigger life he calls them to. This is not a smaller faith that requires less of us. It is a fuller faith that offers more, including the presence of God himself working transformation from within. The law trained Israel for what was coming. Now that Jesus has come, believers are free to live the law's deepest intention, not as slaves under a curse but as beloved children ruling the estate with their brother, the risen King.
