What does the Bible say about the role of the law in salvation?

In Romans 7:7, the Apostle Paul articulates the purpose of the law by stating, 'I would not have known sin except through the law.' This indicates that the law serves as a mirror reflecting our sinful nature and our inability to achieve righteousness through our efforts. It exposes the depths of human sinfulness, driving us to recognize our need for a Savior. While the law is good and holy, it cannot bestow salvation; only faith in Christ can do that. We see this exemplified in Psalm 25:5, where the psalmist seeks guidance from God as the ultimate source of salvation, affirming that reliance on divine mercy and grace is essential for real hope.
