HEART OF FLESH

He doesn't say, "I will remove their will of stone from their flesh and give them a will of flesh," but rather, Ezekiel 19 And I will give them one heart, and a new spirit I will put within them. I will remove the heart of stone from their flesh and give them a heart of flesh;

The will in a heart of stone is bound by the nature of stone, the will in a heart of flesh is bound by the nature of flesh
