How can we replace our deceitful heart according to the Bible?

The Gospel does not just attempt to improve or rehabilitate our old hearts; it offers a complete transformation by giving us a new heart and new desires. Ezekiel 36:26 speaks of God replacing our heart of stone with a heart of flesh, illustrating the profound change that occurs in believers. This new heart allows us to have new affections that align with God's will. While we receive this new heart through faith in Christ, we are still called to test everything against Scripture, ensuring that our thoughts and desires are in line with God's truth.
