What does the Bible say about salvation and the law?

The Bible clearly states that by the deeds of the law, no flesh will be justified in the sight of God (Romans 3:20). Salvation is not based on our ability to keep the law, as no one can fulfill its demands. Instead, the gospel establishes the law because Christ, through His obedience, fulfilled the law on our behalf. Therefore, true salvation comes only through the grace found in Jesus Christ, who is Himself our law-keeping righteousness. The Pharisees' teaching, which emphasized salvation through legalistic observance, stands in stark contrast to the gospel of grace, which reveals that it is God who saves His people, not the works of man.
