Why is Jesus' fulfillment of the law important for Christians?

The fulfillment of the law by Jesus is of paramount importance in Reformed theology as it underscores the concept of imputed righteousness for believers. According to Galatians 4:4, 'But when the fullness of the time was come, God sent forth his Son, made of a woman, made under the law, to redeem them that were under the law.' Jesus lived a perfect, sinless life and fulfilled every aspect of the law on behalf of His people. This active obedience, combined with His sacrificial death, ensures that believers are not under the condemnation of the law but are reconciled to God through faith in Christ. This is the heart of the gospel message and the essence of sovereign grace: that righteousness comes not from our obedience but through the obedience of Christ.
