Faith is essential as it is through faith that we are justified, not by the works of the law.
In Reformed theology, the relationship between faith and the law is foundational. Galatians 3:24 states that the law was our schoolmaster to bring us unto Christ that we might be justified by faith. This emphatically underlines that adherence to the law cannot achieve righteousness; rather, faith alone heals the breach caused by sin. The law exposes our shortcomings, making clear our desperate need for a Savior. When individuals put their faith in Christ, they fulfill the law's demands not by their works, but through the imputed righteousness of Christ, who kept the law perfectly. Thus, faith in Christ does not abolish the law but fulfills it, as believers live out the moral implications of God’s law with new hearts regenerated by the Holy Spirit.
