How do works and grace differ in Christian belief?

In Christian theology, particularly in the Reformed tradition, works and grace represent two opposing approaches to salvation. Works rely on human effort and merit, suggesting that one's deeds can earn God's favor. This is contrasted with grace, which is the unearned, unmerited favor of God toward sinners, as emphasized in Ephesians 2:8-9. In a grace-based faith, salvation is wholly dependent on Christ's work on the cross rather than human achievements. This distinction is crucial, as it highlights the truth that true redemption comes not from our efforts but from God’s sovereign grace through faith in Jesus Christ.
