Why is the concept of grace versus works important for Christians?

The sermon contrasts the religion of grace with the religion of works, emphasizing that only through grace can one achieve salvation. This distinction is crucial for Christians because it affects our understanding of how we relate to God and serve Him. In a grace-based theology, salvation is a gift from God, not something earned through human effort. Ephesians 2:8-9 underscores that we are saved by grace through faith, not by works, so no one can boast. This understanding leads to a genuine expression of faith, resulting in good works that are done in gratitude for God's grace rather than as attempts to earn His favor.
