In Matthew 5:17, Jesus says that He did not come to abolish the law but to fulfill it. What does it mean? Some Christians might ask, if we are saved by grace and are no longer indebted to the Law, why does the Law have to be fulfilled? Simply put, sin is disobedience to God's Law. So, if Jesus did not fulfill the Law and the Law remains violated, then God's judgment upon the guilty remains in force. But Jesus set us free, first by fulfilling the Law we violated with His perfect obedience even unto death, then by bearing God's judgment in our place. Therefore, the fulfillment of the Law by Jesus Christ is the core aspect of God's redemption of the lost. Since the Law is perfectly fulfilled by Jesus Christ through His righteous living and submission to the full term of the Law, those who are clothed with His righteousness and set free by His substitutionary death are no longer in debt to the Law.
