How does the law relate to salvation in the Bible?

The relationship between the law and salvation is crucial in understanding the need for redemption. The law serves as a mirror, exposing our sinfulness and inability to achieve perfection, which is required for salvation. Romans 3:20 explains that through the law comes the knowledge of sin. The law was never intended to save but to lead us to Christ, who fulfills the demands of the law on our behalf. It shows us that we cannot save ourselves through our own efforts, thus increasing our reliance on the grace of God realized through Jesus Christ. The ceremonial law illustrated the need for a perfect sacrifice, which Christ provided once for all, as articulated in Hebrews 10.
