Why is God's grace important in salvation?

In Reformed theology, God's grace is the cornerstone of salvation. Ephesians 2:8-9 makes clear that we are saved by grace through faith, a gift from God, not a result of works. This emphasizes God's unmerited favor bestowed upon sinners, affirming that no one can earn salvation through their own efforts. The account of Naaman illustrates grace vividly; he receives healing not because of his status or deeds, but purely through faith in God’s promise as conveyed by the prophet. In recognizing that salvation is a work initiated and completed by God, believers are called to trust in Christ alone for their redemption, which reinforces the Five Solas and the truth that salvation is entirely a work of grace.
