God’s promise to Abraham was a gift of grace, not something earned through effort. When the law came centuries later, it didn’t cancel or replace that promise—it revealed just how much we need it. The law exposed our sin and humbled us, like a stern tutor preparing us for the arrival of Christ. But now that Christ has come, we are no longer under the law—we are adopted as God’s children through faith, fully loved and fully accepted. In Jesus, we are united, made heirs of a rich inheritance that includes not only forgiveness and the Spirit now, but the whole world to come. From beginning to end, our standing with God rests not on what we do, but on what Christ has done.

Justification with God comes not by law-keeping or moral performance but by faith alone in Jesus Christ. Paul shows that all who rely on works are under a curse because no one perfectly keeps God's law. But God gave Abraham righteousness through faith before the law or circumcision, and that same blessing—peace with God and his abiding presence—is extended to Jew and Gentile alike. Christ redeems sinners from the curse by becoming a curse for them, bearing God’s wrath on the cross so that they might receive the promised Spirit through faith and become true children of Abraham.
