Christ fulfills the law for believers by taking their place and achieving perfect righteousness through His life and sacrifice.
Christ's fulfillment of the law on behalf of believers is a central tenet of the gospel. Romans 8:3 says that God sent His own Son in the likeness of sinful flesh and for sin, to condemn sin in the flesh, so that the righteousness of the law might be fulfilled in us. Believers are freed from the law's condemnation because Christ, by His perfect obedience and sacrificial death, satisfied God's holy requirements. This righteousness is imputed to us through faith in Him, granting us acceptance before God not based on our own merits, but on the completed work of Christ.
