Will the heavens and earth pass away one day?... If so .. Will the law as well?... Seems to me Yeshua is implying this...Or is the law eternal ?.. I know Hashem makes a new covenant with the house of Israel one day.. So which covenant is eternal?... The covenant made on mount Sinai or the new covenant yet to come under the messiah?
In like manner, the 'New Covenant' is more of a Re-Newed Covenant, in that, it was also given to the children of Israel besides the Covenant received on Mt. Horeb.
"These are the words of the Covenant which YHWH commanded Moshe to make with the children of Israel in the land of Moab, beside the Covenant which he made with them in Horeb...
...Keep therefore the words of this Covenant, and perform them, that you may prosper (be blessed) in all of your endevors; Everyone of you which stand before YHWH your Elohey, your captains of your tribes, your elders, and all of your officials of Israel, your little ones, your wives, and your foreigners that are in your camp, from the hewer of wood, unto the drawer of water, that you may enter into this Covenant with YHWH your Elohey...
...Neither with you alone do I make this Covenant and Promise, but with them who stand here with us Today before YHWH our Elohey, and also those who are not with us here Today...
...Yet YHWH has not given you a heart to perceive, nor eyes to see, or ears to hear unto Today...
...Therefore YHWH your Elohey will circumcise your heart, and the heart of your seed, to love YHWH your Elohey with all of your heart, and all of your soul, that you may live...
...If you will Listen unto the Voice of your Elohey, to keep his commandments, and his statutes which are written in this book of the Torah/Law, if you turn unto Elohey with all of your Heart, and with all of your Soul...
For this commandment which I command you Today, it is not hidden from you, neither is it FAR off; It is not in Heaven, that you need to inquire, who shall go up to Heaven, and bring it back for us? that we may hear it, and perform it! But the Word is very NEAR unto you, in your mouth, and in your heart, so you can perform it". Deut. 29 & 30]
I create the fruit of the lips; Peace, peace to him that is FAR off, and unto him that is NEAR, says YHWH, and I will heal him. But the Wicked are like the troubled sea when it can not rest, whose waters cast up debri, and mud. [Isa. 57:19-20]
Who have said ....Our lips are our own: [Ps. 12:4]
While the predisposition of a man's heart, and the reply of the tongue belongs to YHWH. [Prv. 16:1]
Therefore it is not you that speak, but the Spirit of your Father that speaks through you. [Matt. 10:20]
According to these passages the (New) Covenant has long been in existence, and was never exclusive to the children of Israel, yet it and the written Torah are of the same:
One is sown in your Heart, and the other on a table(t) to nurture ones Soul (mind, spirit), that we may learn to obey him with both our Heart & Soul; those who have taken hold of the (Re-)New(-ed) Covenant are those who are Near, and those who still believe their lips are their own are Far off, for Y'shua says the Kingdom is at hand, meaning both near and available, not, far off, or yet for some time to come.
YHWH clarifies, that, it is the condition of one's heart that enables (or disables) one to perceive with their heart, see with their eyes, or hear with their ears that which is otherwise already evident, and in effect.
When we do not believe him, we make him out to be a liar, and the very truth itself appears unbelievable, consequently the disbeliever is handed over to a delusion, and Elohym ensures that they are convinced in their own lie. (See 2Thesalonians 2:12)
One does not see Divinely Ordained Priests, Anoited Prophets, or Appointed Kings as before, probably because, one is expecting to see someone greater than themself (who are but) Divinely Appointed Kings, priests, and Prophets who (when standing), literally have their buttocks resting on His Throne (i.e. Heaven, our atmosphere), and their feet resting on His footstool (Earth).
Though some intetpretative, and customary laws, and practices have come to a halt, it is the Mediatorship that was...well, more or less absorbed, rather than done away with, for we were originally called Christians, because we claimed to be Anointed beings, since the anointing of Ruach H'Kodesh many of us have fallen back to sleep, thus many of us know the words, but not their meanings, (See Isa. 29); Because the Torah and the (New) Covenant are (content wise) one in the same, one can destroy a copy of the Torah (which is but a sacred photograph), but the the Torah itself is as eternal as its Author.
"The grass withers, the flower fades; but the Word of our Elohey shall stand forever.
