How do we know Christ is the fulfillment of the Law of Moses?

The actions and statements of Christ affirm Him as the fulfillment of the Law of Moses. In John 5:46, Jesus states, 'For if you believed Moses, you would believe Me; for he wrote about Me.' The Old Testament sacrificial system, particularly exemplified in the Day of Atonement, foreshadowed the perfect sacrifice of Christ. He alone accomplished the full and final atonement for sin, as seen in Hebrews 9:26, which declares that 'Christ was sacrificed once to take away the sins of many.' Through His death and resurrection, the requirements of the Law were fully satisfied, rendering Him not just a follower of the Law but its ultimate completion.
