Christ is the end of the law for righteousness because he fulfills the law's demands on behalf of his people (Romans 10:4).
Romans 10:4 states, 'For Christ is the end of the law for righteousness to everyone that believes.' This declaration signifies that Christ has perfectly fulfilled the requirements of the moral, ceremonial, and civil law for his people. The law was never intended to provide righteousness but rather to expose sin and reveal our need for a Savior. Since Christ has completed the law's requirements, believers are no longer under its condemnation. Instead, we are seen as righteous in God's eyes because of Christ's obedience and sacrifice, thus freeing us from the law's demands and enabling us to rest in his grace.
