AND THE ETERNAL THY G-D WILL CIRCUMCISE THY HEART. It is this which the Rabbis have said, “If someone comes to purify himself, they assist him” [from on High]. The verse assures you that you will return to Him with all your heart and He will help you.This following subject is very apparent from Scripture: Since the time of Creation, man has had the power to do as he pleased, to be righteous or wicked. This [grant of free will] applies likewise to the entire Torah-period, so that people can gain merit upon choosing the good and punishment for preferring evil. But in the days of the Messiah, the choice of their [genuine] good will be natural; the heart will not desire the improper and it will have no craving whatever for it. This is the “circumcision” mentioned here, for lust and desire are the “foreskin” of the heart, and circumcision of the heart means that it will not covet or desire evil. Man will return at that time to what he was before the sin of Adam, when by his nature he did what should properly be done, and there were no conflicting desires in his will, as I have explained in Seder Bereshith. It is this which Scripture states in [the Book of] Jeremiah, Behold, the days come, saith the Eternal, that I will make a new covenant with the house of Israel, and with the house of Judah; not according to the covenant that I made with their fathers etc. But this is the covenant that I will make with the house of Israel after those days, saith the Eternal, I will put my Law in their inward parts, and in their heart will I write it. This is a reference to the annulment of the evil instinct and to the natural performance by the heart of its proper function. Therefore Jeremiah said further, and I will be their G-d, and they shall be My people; and they shall teach no more every man his neighbor, and every man his brother, saying: ‘Know the Eternal;’ for they shall all know Me, from the least of them unto the greatest of them. Now, it is known that the imagination of man’s heart is evil from his youth and it is necessary to instruct them, but at that time it will not be necessary to instruct them [to avoid evil] for their evil instinct will then be completely abolished. And so it is declared by Ezekiel, A new heart will I also give you, and a new spirit will I put within you; and I will cause you to walk in My statutes. The new heart alludes to man’s nature, and the [new] spirit to the desire and will. It is this which our Rabbis have said: “And the years draw nigh, when thou shalt say: ‘I have no pleasure in them’ — these are the days of the Messiah, as they will offer opportunity neither for merit nor for guilt,” for in the days of the Messiah there will be no [evil] desire in man but he will naturally perform the proper deeds and therefore there will be neither merit nor guilt in them, for merit and guilt are dependent upon desire. If Jesus Christ is truly the Messiah and all his followers are truly the talmudim of him, there will be no sin and [evil] desire among them. If the [evil] inclination instead grows among the people, it proves there is no circumcised heart, which means it’s not the days of the Messiah.
Deuteronomy 30:6: And HaShem thy G-d will circumcise thy heart, and the heart of thy seed, to love HaShem thy G-d with all thy heart, and with all thy soul, that thou mayest live. (JPS)
Born Haredim like me are fundamentally agnostic about every claim, as we are developing the true unification.
