How do we know God's grace can change a scorner's heart?

The transformation of the heart is foundational in God's salvific work. As discussed in the sermon, the scorner possesses a carnal heart that is inherently rebellious against God. However, when the Spirit of God intervenes, He removes this stony heart of rebellion and replaces it with a heart of flesh that loves God and His word. This miraculous change affirms the promise in Ezekiel 36:26, where God declares that He will give a new heart and spirit. The previous hostility against God is replaced with a desire to obey and honor Him, signifying a genuine transformation through grace.
