What does it mean that Christians receive a new heart in conversion?

The transformation of the heart in conversion is a crucial aspect of salvation. God promises to replace the deceitful and wicked heart of stone with a new heart of flesh (Ezekiel 36:26). This signifies a radical change in the believer's nature, enabling them to follow God's statutes and live in accordance with His will. By receiving a new heart and the Holy Spirit, believers gain the capacity to genuinely seek God and obey His commands, reaffirming the sovereign work of God in their redemption.
