How does Jesus fulfill the requirements of the law for believers?

In Ephesians 2:18, Paul teaches that through Christ, both Jews and Gentiles gain access to God by one Spirit. Jesus is the fulfillment of the law, redeeming His people by His righteous life and sacrificial death. The rituals of the Old Testament, including the Passover, pointed to Him as the ultimate lamb. Believers now celebrate this fulfillment by partaking in the Lord's Supper in remembrance of His saving work, recognizing that true access to God comes not from ritualistic observance but through faith in Christ alone, transforming sinners into His temple.
