What does Galatians say about the works of the law?

In Galatians, Paul repeatedly emphasizes that justification cannot be attained through the works of the law. He argues that if righteousness could come through the law, then Christ's death would be in vain (Galatians 2:21). The Judaizers faced by Paul attempted to impose the law as a requirement for salvation, but Paul confirms that the law reveals our sin and inability, pointing us instead to our need for Christ's redemptive work. This truth solidifies the Reformed doctrine that faith alone in Christ is the only means of being justified before God.
