How do we know that Jesus is the fulfillment of the law Moses wrote?

Jesus’ assertion that Moses wrote of Him implies that the entire law and the prophetic writings of Moses point to the necessity of a Messiah. Jesus embodied the law's requirements; He lived a perfect life of obedience, satisfying all legal demands on our behalf. For instance, His reference to the ceremonial law demonstrates how every sacrifice, including the Passover lamb, was ultimately fulfilled in His sacrificial death on the cross. Throughout the New Testament, such as in Romans 10:4, it is affirmed that Christ is the end of the law for righteousness to everyone who believes, confirming His role as the culmination of what Moses wrote.
