Why is the grace of God pivotal in the Christian faith?

Grace is foundational in Christianity because it represents God's unmerited favor towards sinners. According to Ephesians 2:8-9, believers are saved by grace through faith, which emphasizes that salvation is a gift from God, not a result of human works. This grace transforms lives, enabling believers to live in a manner that reflects their new identity in Christ. Furthermore, it assures believers of God's continued presence and support throughout their spiritual journey, as seen in Romans 8:31-39, which highlights God's unwavering love and commitment to His children. Without grace, the entirety of the Christian experience, from salvation to sanctification, would be undermined.
