Changed heart? So, how does a man change his heart? He doesn’t. God changes his heart. But the man must put himself before the King in such a way that God can change his heart. It must become his highest priority, and this is where being resolute is required.
“Moreover, I will give you a new heart and put a new spirit within you; and I will remove the heart of stone from your flesh and give you a heart of flesh.”Ezekiel 36:26 NASB
A Changed heart is a new creation in Christ! You have new desires, new thoughts, etc. It is a 180! Not a 360!
