In Galatians 3:15–22, Paul explains that God’s promise to Abraham came long before the law—and the law didn’t cancel or replace it. The promise was always pointing to Christ, the true “offspring” of Abraham, through whom the blessing would come. The law was given later to reveal sin, not to give life or replace faith. In short, God’s promise stands firm—our inheritance comes by faith in Christ alone, not by keeping the law.
