Ezekiel 11:19

‘I will give them a heart to know Me, for I am Yahweh; and they will be My people, and I will be their God, for they will return to Me with their whole heart.

and I will give them one heart and one way, that they may fear Me always, for their own good and for the good of their children after them.

“Cast away from yourselves all your transgressions which you have committed and make yourselves a new heart and a new spirit! Now why will you die, O house of Israel?

“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.

“And I will put My Spirit within you, and you will come to life, and I will place you on your own land. Then you will know that I, Yahweh, have spoken and done it,” declares Yahweh.’”

being manifested that you are a letter of Christ, ministered to by us, having been written not with ink but with the Spirit of the living God, not on tablets of stone but on tablets of hearts of flesh.
