29 But he is a Jew, who is one inwardly; and the circumcision is that of the heart, by the Spirit,5 and not by the letter; whose praise is not from men, but from God. [The Spirit circumcises your heart, cutting away the sins as you wait on God to receive his grace that both charges sin and then removes sin, purifying a peculiar people zealous for good works. Reading about sin in the Bible does not remove the desire for sin from your heart; only the Spirit does that.]
19 And I will give them one heart and I will put a new spirit within them; and I will take the stony heart out of their flesh, and will give them a heart of flesh,
31 Cast away from you all your transgressions, by which you have transgressed; and get a new heart, a new mind, and a new spirit. For why will you die1, O house of Israel?
32 For I have no pleasure in the death of him who dies," says the Lord GOD. "Therefore turn [from your evil ways] and live!"
26 I will also give you a new heart, and I will put a new spirit within you, and I will take away the stony heart out of your flesh, and I will give you a heart of flesh.1 [The stony heart symbolizes the stubborn, evil heart in all men; the fleshly heart symbolizes the heart that is submissive and obedient to God.]
7 And I will give them a heart to know me, that I am the LORD; and they shall be my people, and I will be their God for they shall return to me with their whole heart.
33 "But this shall be the covenant that I will make with the house of Israel. After those days," says the Lord, "I will put my law in their inward parts, and write it in their hearts; and I will be their God, and they shall be my people.
34 And they shall no longer teach every man his neighbor, and every man his brother, saying, 'Know the LORD,' for they shall all know me, from the least of them to the greatest of them," says the Lord, "for I will forgive their iniquity, and I will remember their sin no more.1
39 And I will give them one heart, and one way, that they may fear me forever, for the good of them, and of their children after them.
40 And I will make an everlasting covenant with them, which I will not turn away from them to do them good; but I will put my fear in their hearts, so that they shall not depart from me.
