How do we know Jesus fulfilled the law?

Jesus Christ is recognized as the fulfillment of the law because He lived a perfect, sinless life, characterized by complete obedience to God’s commandments. In Matthew 5:17, Jesus declares, 'I came not to destroy, but to fulfill,' indicating that He completes the requirements set forth in the law. Through His life, death, and resurrection, He addresses the penalty of sin and provides a means for sinful humanity to attain righteousness. Consequently, believers are no longer under the law’s condemnation but are seen as justified through Christ, who grants them His righteousness.
