How does the law of Moses relate to grace?

The law serves as a schoolmaster to bring us to Christ, revealing God's holiness while simultaneously exposing our sinfulness. Romans 7:4 indicates that we are dead to the law through the body of Christ, allowing us to receive grace rather than trying to earn God's favor through works. In fact, where sin abounds, grace does much more abound (Romans 5:20). The law's role is to highlight the necessity of grace, leading us to rely solely on Christ's redemptive work for salvation and sanctification.
