Ezekiel 11:18 They will return to it and remove all its vile images and detestable idols. 19 I will give them an undivided heart and put a new spirit in them; I will remove from them their heart of stone and give them a heart of flesh. 20 Then they will follow my decrees and be careful to keep my laws. They will be my people, and I will be their God.
I am a sinner and when I read these passages I am reassured that through the grace and forgiveness of the Lord my heart (the center of my thoughts) can be renewed!
