Why is grace essential in the Christian faith?

Grace is foundational to Christianity as it signifies God's unmerited favor towards sinners. According to Romans 5:20, where sin abounds, grace abounds much more. This means that no matter the depth of sin, God's grace surpasses it providing forgiveness and new life. It is through grace that believers are justified, adopted into God's family, and empowered to live in accordance with His will. Without grace, the burden of sin would be unbearable, but through grace, they find strength and assurance of salvation.
