How do we know that Christ is the fulfillment of the law?

Christ is the fulfillment of the law because He completed what the Old Testament sacrificial system and priesthood foreshadowed. Romans 10:4 states, 'For Christ is the end of the law for righteousness to everyone that believes.' This means that all the requirements of the law pointed to Him and find their ultimate expression in His person and work. Jesus did not come to abolish the law; rather, He came to fulfill it, bringing it to its intended completion. The practices once mandated were mere shadows of the reality found in Christ, who offers a new way to God through His righteousness and sacrifice.
