Why is grace essential in Christianity?

Grace is at the heart of the Christian faith, emphasizing God's unmerited favor towards sinners deserving of condemnation. According to Scripture, salvation is by grace through faith, as captured in Ephesians 2:8-9: 'For by grace are ye saved through faith; and that not of yourselves: it is the gift of God.' This grace is not only pivotal for initial salvation but also for ongoing sanctification. Believers rely on God’s grace to empower them to live in accordance with His will, reflecting the truth of His character. Therefore, understanding and experiencing grace draws believers into a deeper relationship with God, encourages unity among them, and strengthens their testimony of Christ to the world.
