How do we know grace is more important than the law?

Grace stands as the cornerstone of salvation, which the Apostle Paul emphasizes repeatedly throughout his letters. In Galatians, he insists that the law could never justify a person before God (Galatians 3:10). The law serves to expose sin and our utter need for a Savior, whereas grace is the unmerited favor of God that completely covers our sin through the sacrifice of Jesus Christ. Hence, it is by grace that we are saved, making it far more critical for the believer than the law, which merely points us to our need for that grace through faith.
