Do not be conformed to this world, but be transformed by the renewing of your mind. Then you will be able to discern what is the good, pleasing, and perfect will of God. Romans 12:2

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; so that they may walk in my statutes and keep my rules and obey them. And they shall be my people, and I will be their God. Ezekiel 11:19-20
