Why is the concept of salvation by grace important for Christians?

The concept of salvation by grace is central to the Gospel message, as articulated in Ephesians 2:8-9, which states that we are saved by grace through faith, not of works, lest anyone should boast. This truth eradicates any notion of self-righteousness and underscores the necessity of relying solely on Christ for salvation. It is important because it affirms that our relationship with God is not performance-based but grounded in His love and mercy. This understanding fosters humility and gratitude in believers, motivating them to live in a manner that reflects the transformative power of God's grace in their lives.
