Why is it important for Christians to distinguish between grace and works?

The distinction between grace and works is fundamental for Christians, as it shapes our understanding of salvation. Ephesians 2:8-9 states that we are saved by grace through faith, and not of ourselves; it is the gift of God, not of works, lest anyone should boast. When we rely on our deeds, we undermine the grace of God and revert to a system that cannot lead to righteousness. Rather, grasping grace enables us to acknowledge our total dependence on Christ, cultivating humility and true assurance of salvation. This recognition ensures we do not build a house of works but reside in the safe haven of grace built by our Savior.
