How is grace opposed to works in salvation?

The distinction between grace and works is a fundamental tenet of Reformed theology. Ephesians 2:8-9 clarifies that salvation is a gift of God, not a result of works, so that no one can boast. This positions grace as God's unmerited favor toward sinners, highlighting that human effort has no contribution toward achieving salvation. Instead, grace assures believers that their righteousness before God is based solely on Christ's obedience and sacrifice. This notion liberates believers from the burden of having to earn favor with God and affirms their identity in Christ as recipients of grace.
