As we take a look at this issue of faith, our review should begin with a discussion of the righteousness of MASHIACH as expressed in his own words:

Mattithyahu (Matthew) 5:17-18

Think not that I am come to destroy the Torah, or the prophets: I am not come to destroy, but to fulfil. 18 For verily I say unto you, Till heaven and earth pass, one Yod or one tittle shall in no wise pass from the Torah, till all be fulfilled.

There is a lot of argument as to what the word fulfilled might mean.  The antinomians take this as meaning that the Torah was then finished, done away with, completed, etc.  The rationale however is clearly suspect, given the edicts of the Torah, such as I AM YAHUAH ELOHIYM.  How is that rendered obsolete?

In the Greek, the word fulfilled is γινομαι (ginomai) which means in the first instance to cause to be; to come into being; to arise; or to come to pass. It also means to grow, to happen, to have, to be kept, to be made, to be married, to be ordained, to partake, to pass, to be performed, to be published, et cetera.

Think not that I am come to destroy the Torah, or the prophets: I am not come to destroy, but to (bring into being). 18 For verily I say unto you, Till heaven and earth pass, one Yod or one tittle shall in no wise pass from the Torah, till all is brought into being (or, till all has arisen; or, till all has come to pass; or till all has come to be).

Remember that it is the Torah that has Mosheh giving his own prophecy:

Devariym (Deuteronomy) 18:15

YAHUAH your ELOHIYM will raise up unto you a Prophet from the midst of you, of your brethren, like unto me; unto him ye shall hearken; 16 According to all that you desired of YAHUAH your ELOHIYM in Chorev in the day of the assembly, saying, Let me not hear again the voice of YAHUAH my ELOHIYM, neither let me see this great fire anymore, that I die not. 17 And YAHUAH said unto me, They have well spoken that which they have spoken. 18 I will raise them up a Prophet from among their brethren, like unto you, and will put my words in his mouth; and he shall speak unto them את (eth) all that I shall command him. 19 And it shall come to pass, that whosoever will not hearken unto my words which he shall speak in my name, I will require it of him. 20 But the prophet, which shall presume to speak a word in my name, את (eth) which I have not commanded him to speak, or that shall speak in the name of other gods, even that prophet shall die. 21 And if you say in your heart, How shall we know the word which YAHUAH has not spoken? 22 When a prophet speaks in the name of YAHUAH, if the thing follow not, nor come to pass, that is the thing which YAHUAH has not spoken, but the prophet has spoken it presumptuously: you shall not be afraid of him.

This is just an example of one portion of the Torah that would yet be fulfilled in Mashiach.  Consider also the Song of Mosheh, bearing in mind that not one YOD and not one tittle will pass away until all is fulfilled:

Devariym (Deuteronomy) 32

GIVE ear, O ye heavens, and I will speak; and hear, O earth, the words of my mouth. 2 My doctrine shall drop as the rain, my speech shall distil as the dew, as the small rain upon the tender herb, and as the showers upon the grass: 3 Because I will publish the name of YAHUAH: ascribe ye greatness unto our ELOHIYM. 4 He is the Rock, his work is perfect: for all his ways are judgment: an EL of Truth and without iniquity, just and right is he. 5 They have corrupted themselves, their spot is not the spot of his children: they are a perverse and crooked generation. 6 Do ye thus requite YAHUAH, O foolish people and unwise? is not he your Father that has bought you? has he not made you, and established you?

7 Remember the days of old, consider the years of many generations: ask your father, and he will show you; your elders, and they will tell you. 8 When EL ELYON divided to the nations their inheritance, when he separated the sons of men, he set the bounds of the people according to the number of the children of Yisra’el. 9 For YAHUAH’S portion is his people; Ya`aqov is the lot of his inheritance. 10 He found him in a desert land, and in the waste howling wilderness; he led him about, he instructed him, he kept him as the apple of his eye. 11 As an eagle stirs up her nest, flutters over her young, spreads abroad her wings, takes them, bears them on her wings: 12 So YAHUAH alone did lead him, and there was no strange god with him. 13 He made him ride on the high places of the earth, that he might eat the increase of the fields; and he made him to suck honey out of the rock, and oil out of the flinty rock; 14 Butter of kine, and milk of sheep, with fat of lambs, and rams of the breed of Bashan, and goats, with the fat of kidneys of wheat; and you did drink the pure blood of the grape.

15 But Yasharon waxed fat, and kicked: you are waxen fat, you are grown thick, you are covered with fatness; then he forsook ELOAH which made him, and lightly esteemed the Rock of his YAHUSHA. 16 They provoked him to jealousy with strange gods, with abominations provoked they him to anger. 17 They sacrificed unto devils, not to ELOAH; to gods whom they knew not, to new gods that came newly up, whom your fathers feared not. 18 Of the Rock that begat you you are unmindful, and have forgotten EL that formed you. 19 And when YAHUAH saw it, he abhorred them, because of the provoking of his sons, and of his daughters. 20 And he said, I will hide my face from them, I will see what their end shall be: for they are a very froward generation, children in whom is no faith. 21 They have moved me to jealousy with that which is not EL; they have provoked me to anger with their vanities: and I will move them to jealousy with those which are not a people; I will provoke them to anger with a foolish nation. 22 For a fire is kindled in my anger, and shall burn unto the lowest She’ol, and shall consume the earth with her increase, and set on fire the foundations of the mountains. 23 I will heap mischiefs upon them; I will spend my arrows upon them. 24 They shall be burnt with hunger, and devoured with burning heat, and with bitter destruction: I will also send the teeth of beasts upon them, with the poison of serpents of the dust. 25 The sword without, and terror within, shall destroy both the young man and the virgin, the suckling also with the man of gray hairs. 26 I said, I would scatter them into corners, I would make the remembrance of them to cease from among men: 27 Were it not that I feared the wrath of the enemy, lest their adversaries should behave themselves strangely, and lest they should say, Our hand is high, and YAHUAH has not done all this. 28 For they are a nation void of counsel, neither is there any understanding in them. 29 O that they were wise, that they understood this, that they would consider their latter end! 30 How should one chase a thousand, and two put ten thousand to flight, except their Rock had sold them, and YAHUAH had shut them up? 31 For their rock is not as our Rock, even our enemies themselves being judges. 32 For their vine is of the vine of Cedom, and of the fields of Amorah: their grapes are grapes of gall, their clusters are bitter: 33 Their wine is the poison of dragons, and the cruel venom of asps. 34 Is not this laid up in store with me, and sealed up among my treasures? 35 To me belongs vengeance, and recompence; their foot shall slide in due time: for the day of their calamity is at hand, and the things that shall come upon them make haste. 36 For YAHUAH shall judge his people, and repent himself for his servants, when he sees that their power is gone, and there is none shut up, or left. 37 And he shall say, Where are their gods, their rock in whom they trusted, 38 Which did eat the fat of their sacrifices, and drank the wine of their drink offerings? let them rise up and help you, and be your protection. 39 See now that I, even I, am he, and there is no god with me: I kill, and I make alive; I wound, and I heal: neither is there any that can deliver out of my hand. 40 For I lift up my hand to heaven, and say, I live forever. 41 If I whet my glittering sword, and my hand take hold on judgment; I will render vengeance to my enemies, and will reward them that hate me. 42 I will make my arrows drunk with blood, and my sword shall devour flesh; and that with the blood of the slain and of the captives, from the beginning of revenges upon the enemy. 43 Rejoice, O ye nations, with his people: for he will avenge the blood of his servants, and will render vengeance to his adversaries, and will be merciful unto his land, and to his people.

44 And Mosheh came and spoke all the words of this song in the ears of the people, he, and Husha the son of Nun. 45 And Mosheh made an end of speaking all these words to all Yisra’el: 46 And he said unto them, Set your hearts unto all the words which I testify among you this day, which ye shall command your children to observe to do, all the words of this Torah. 47 For it is not a vain thing for you; because it is your life: and through this thing ye shall prolong your days in the land, whither ye go over Yarden to possess it.
