John 1: 14

Matthew 5: 17 "Do not think that I have come to abolish the Law or the Prophets; I have not
come to abolish them but to fulfill them." NIV 1984.

The old Testament is divided in three parts; The Law (Torah), the Prophets, and Ketuvim. As we can see above in Matthew 5:17, at the time of our Lord and Savior Y'SHUA, only the two first parts were cannonical. The third part was added around the year 90 CE at the council of Yavneh - birth of Rabbinic Judaism. So in John 1: 14 what Word was he talking about becoming Flesh? Torah or the Law of course, because the law was given to Jew and Gentile alike at Mount Sinai (Leviticus 24:22). Once we go thru the purification process at the end of times, there will be no need for a law anymore, because the law is created out of transgression in order to redeem. There will always be a need for (Christ) order, because order is part of perfection or perfect continuity of actions - motions = same state of mind - not changing His or Her ways.

At the end of times there will be no more need to fix the body because it will not be broken anymore, and there will be no more need to heal it because it will be one hundered percent clean (pure).
