How do we know Jesus fulfills the law?

Jesus fulfills the law through His life and sacrificial death, as He is described in Scripture as the embodiment of righteousness. In accordance with Malachi's reference to Levi being a faithful priest, Jesus is the ultimate priest who kept the law blamelessly, as mentioned in 1 Peter 2:22. The Old Testament sacrifices were mere shadows of the reality found in Christ, and thus, by offering Himself, He not only fulfilled the requirements of the law but also satisfied the justice of God regarding sin, as depicted in Hebrews 10:14.
