How do we know that Jesus fulfilled the law and the prophets?

In Matthew 5:17, Jesus explicitly stated, 'Think not that I am come to destroy the law, or the prophets; I am not come to destroy, but to fulfill.' This proclamation aligns with the entirety of Old Testament prophecy, which spoke of His coming, His life, and His sacrificial death. From fulfilling the ceremonial aspects of the Law to embodying the moral imperatives therein, Jesus is understood as the complete embodiment of both Law and prophecy. His life and ministry exemplified perfect obedience, and ultimately, His atoning death met the law's requirements for sin. Thus, He is both the lawgiver and the law-fulfiller.
