What does it mean to have a new heart according to the Bible?

Ezekiel 36:26 provides a powerful depiction of the transformative nature of conversion: 'A new heart also will I give you, and a new spirit will I put within you.' This change signifies that God takes away the heart of stone, characterized by rebellion and sinfulness, and replaces it with a heart of flesh, responsive to His will and infused with spiritual life. This new heart is essential for true obedience and fellowship with God. It embodies the inner transformation that salvation entails, enabling believers to walk in His statutes and keep His judgments, ultimately leading them to a life that glorifies God.
