All was fulfilled - in JESUS. Your position is demolished by this rather simple fact.
Nice how you pick some words of Jesus and leave others out. You left out:
John 8:58 “I tell you the truth,” Jesus answered, “before Abraham was born, I am!”
So… show me in the Word of God, where Jesus said his teachings would be supported, do you see the name Jesus mentioned? God said He declared these things from the beginning and has not kep them hid from our eyes. So, where is it?
Isaiah 9:6 For to us a child is born, to us a son is given, and the government will be on his shoulders. And he will be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace.
God names His son. You can find it in Hosea 11: 1. Why don’t you post up the name that you see for me. Maybe your version says something different?
If not, God said these things were not hid from our eyes and my KJV it is Israel written there as the Son and not Jesus. So, what does your say? Perhaps we do have a misunderstanding in my version.
I am after Truth and in the name of that quest, I looked it up in 20 different English versions all of which name the Son of God as Israel.

A mystery is simply something that man cannot understand:
Job 28:23 God understands the way to it and he alone knows where it dwells,
Psalm 147:5 Great is our Lord and mighty in power; his understanding has no limit.
Our understanding does have limits. Clearly, the God of the Old Testament has no problem with pointing out that he understands things man does not.

Proverbs 2: 1-7
Isaiah 43:
7 Even every one that is called by my name: for I have created him for my glory, I have formed him; yea, I have made him.
8 Bring forth the blind people that have eyes, and the deaf that have ears.
9 Let all the nations be gathered together, and let the people be assembled: who among them can declare this, and shew us former things? let them bring forth their witnesses, that they may be justified: or let them hear, and say, It is truth.
10 Ye are my witnesses, saith the LORD, and my servant whom I have chosen: that ye may know and believe me, and understand that I am he: before me there was no God formed, neither shall there be after me.
11 I, even I, am the LORD; and beside me there is no saviour.
12 I have declared, and have saved, and I have shewed, when there was no strange god among you: therefore ye are my witnesses, saith the LORD, that I am God.
13 Yea, before the day was I am he; and there is none that can deliver out of my hand: I will work, and who shall let it?
And to those only quoting
a verse out of Job… read the whole book and not just one verse. When Job was able to see that man’s knowledge could not save him, God fed him knowledge from His own mouth.
I am giving you knowledge that comes from God and so no one is declaring me wrong, but rather God wrong.

Oh, and for the schpill about not including the rest of the passage, the end of Psalm 147 declares exactly who it is you can go to to gain the knowledge of God.
19 He sheweth his word unto Jacob, his statutes and his judgments unto Israel.
20 He hath not dealt so with any nation: and as for his judgments, they have not known them. Praise ye the LORD.
He declares it… the nations have not been dealt with by God as has Jacob, Israel and thus, they cannot know the judgments of God save by the Son of God, which is declared as Israel.
