What is the role of God's grace in transforming our hearts?

God's grace plays a foundational role in heart transformation as it is only by His power that we can experience true repentance and new life. In John 3:3, Jesus emphasizes that one must be born again to see the Kingdom of God, which underscores our need for God's initiating grace. Through His grace, He enables us to cry out for a new heart, recognizing our helpless state—'Lord, I need a new heart' conveys our complete reliance on Him. Ultimately, grace is what redeems us, sanctifies us, and sustains us in our walk with Christ, confirming that all transformation stems from His unearned favor.
