How does the law relate to salvation in the context of grace?

In the context of grace, the law serves to expose our sinfulness and the impossibility of achieving righteousness through our own efforts. Romans 3:20 states, 'For by the law is the knowledge of sin.' This understanding leads to the realization that salvation is not based on law-keeping but is a free gift of grace through faith in Jesus Christ. Thus, Galatians 2:16 reiterates, 'Knowing that a man is not justified by the works of the law but by faith in Jesus Christ.' The law, by its very nature, shows our inability to uphold God’s standards, guiding the sinner to recognize their need for a Savior. Therefore, Christians must reject any notion that our works add to Christ's righteousness; we are to wholly rely on His grace alone.
