HETEROSIS 

Thanks to CM who played a recording of another person who gave the name of Heterosis which means that it is essentially a Prophetic talk, that when Yehovah has prophets speak of Yeshua, Yeshua did not exist but will exist, it is foreknowledge of an event which you see in 1 Peter 1:20 (Proegnosmenou) "Foreknew before the foundation of the earth".  This is heterosis Yeshua was foreknown before the world began so he did not exist but God's plan of Yeshua did and Yeshua's resurrection did not exist in time until the event happened and was revealed in the time which it played out, this is Heterosis.  We know the whole old testament is essentially pointing to Yeshua's coming as the Messiah, that he is the sacrifice, he is the suffering servant, he is the chosen one Isaiah 42:1 - 1“Here is My Servant, whom I uphold, My Chosen One, in whom My soul delights. I will put My Spirit on Him, and He will bring justice to the nations. / this is Yeshua, we see how Isaiah 61:1-2 was quoted of Yeshua prophetically which was fulfilled in Luke 4:18-21 again the prophecy of Yeshua come to be in the events that unfolded in the future which is now our past his death, and we also still have some things relating ourselves the true chosen people, and Yeshua in his returning and the Kingdom in Daniel 7:14-27 which partially has been fulfilled where Yeshua goes before the ancient of days that is fulfilled, but then in Daniel 7:25-27 are talking about the saints, the ones who do what is right will be made Kings but this has not physically happened but has already happened in Yehovah's mind for us, this is Heterosis just as Yeshua being the son of man before ancient of days which Is Yehovah, and that he is made King over all kings which is he being King over us as kings under him.   We also see in Isaiah 65:17 - 17For behold, I will create new heavens and a new earth. The former things will not be remembered, nor will they come to mind. / which also itself lines up with what Yeshua himself said in Matthew 5:18 - 18For I tell you truly, until heaven and earth pass away, not a single jot, not a stroke of a pen, will disappear from the Law until everything is accomplished. // So notice heaven and earth passing and also that nothing leaves the law until all is accomplished, this has not yet been accomplished even now as we see in another correlating verse in Revelation 21:1 - Then I saw a new heaven and a new earth; for the first heaven and the first earth passed away, and there is no longer any sea. / again this is clearly Heterosis which is events that have not happened but will happen and Yeshua knew this has to happen, so all things have not yet been fulfilled but will and we will be made Kings those who are true Unitarian messianic believers who keep the Torah observed to the end, so while we are not Kings now I can say I will be I know this glory is promised to those who obey this is a glory God will give me and my brothers and sisters when we achieve overcoming the world, again heterosis prophecy that will come to be but is not yet, which is why Yeshua can speak bluntly of his glory before it existed as if he had it, because Yehovah does not lie so he already did have it, and was given what was promised as will we if we do as he says.
We see we are foreknown as well in other passages in new testament, we are destined to be conformed to the image of his son, so Yeshua will be first of many brothers, the first born from the dead:  Romans 8:29-30 - 29 For those whom He foreknew, He also predestined to become conformed to the image of His Son, so that He would be the firstborn among many brothers and sisters; 30 and these whom He predestined, He also called; and these whom He called, He also justified; and these whom He justified, He also glorified. / also this correlates to Colossians 1:15-18 - 15 [a]He is the image of the invisible God, the firstborn of all creation: 16 for [b]by Him all things were created, both in the heavens and on earth, visible and invisible, whether thrones, or dominions, or rulers, or authorities—all things have been created through Him and for Him. 17 He [c]is before all things, and in Him all things [d]hold together. 18 He is also the head of the body, the church; and He is the beginning, the firstborn from the dead, so that He Himself will come to have first place in everything. /

Jeremiah 1:5 - 5 “Before I formed you in the womb I knew you, And before you were born I consecrated you; I have appointed you as a prophet to the nations.”
(Jeremiah 1:5 is heterosis of Jeremiah's existence, does this make him some how Yehovah since God knew of him also before he existed?  No!  Simply that Yehovah knew of all things before they played out.)

Statements like John 8:58 before Abraham was I am is heterosis because firstly we see in John 8:40 that Yeshua said he is a man who hears from God not that he is God Yehovah, secondly he relays truth from God which he hears, so it wouldn't make sense of Yeshua to say "I am a man you're trying to kill for telling you the truth I heard from God, but I am God the I am as I am before Abraham." for example, I mean it just doesn't make sense what so ever, unless you take into consideration that Yehovah has planned Yeshua not only to be above all rulers even angels and all creation but under Yehovah himself 1 Corinthians 15:27-28 but he is also before Abraham in the creation from resurrection from the dead Colossians 1:15-18, he is born before Abraham because he is the first born among many brothers and first born from dead Romans 8:29-30, Colossians 1:15-18 which again shows the fuller context to Yeshua being before Abraham.
John 8:40 - 40 But as it is, you are seeking to kill Me, a man who has told you the truth, which I heard from God; this Abraham did not do. / When you see this whole chapter it is figurative speech he says in in John 8:41-47 - 41 You are doing the deeds of your father.” They said to Him, “We were not born as a result of sexual immorality; we have one Father: God.” 42 Jesus said to them, “If God were your Father, you would love Me, for I came forth from God and am here; for I have not even come [a]on My own, but [b]He sent Me. 43 Why do you not understand [c]what I am saying? It is because you cannot listen to My word. 44 You are of your father the devil, and you want to do the desires of your father. He was a murderer from the beginning, and does not stand in the truth because there is no truth in him. Whenever he tells [d]a lie, he speaks from his own nature, because he is a liar and the father of [e]lies. 45 But because I say the truth, you do not believe Me. 46 Which one of you convicts Me of sin? If I speak truth, why do you not believe Me? 47 The one who is of God hears the words of God; for this reason you do not hear them, because you are not of God.” / Notice the figurative speech and some clear statements that, the one who is of God hears what God says, that their Father is satan, why?  Because you are of the one you obey.  So notice the context to what is said in John 8 is figurative speech he didn't say literally he exists before Abraham in physical birth, no it is talking figuratively of the resurrection and from the Dead a new creation, the new birth.  John 8:48-55 - 48 The Jews answered and said to Him, “Do we not rightly say that You are a Samaritan, and You have a demon?” 49 Jesus answered, “I do not have a demon; on the contrary, I honour My Father, and you dishonor Me. 50 But I am not seeking My glory; there is One who seeks it, and judges. 51 Truly, truly I say to you, if anyone follows My word, he will never see death.” 52 The Jews said to Him, “Now we know that You have a demon. Abraham died, and the prophets as well; and yet You say, ‘If anyone follows My word, he will never taste of death.’ 53 You are not greater than our father Abraham, who died, are You? The prophets died too. Whom do You make Yourself out to be?” 54 Jesus answered, “If I glorify Myself, My glory is nothing; it is My Father who glorifies Me, of whom you say, ‘He is our God’; 55 and you have not come to know Him, but I know Him. And if I say that I do not know Him, I will be a liar like you; but I do know Him, and I follow His word. /  You see clearly now that he is not speaking as if he is God, but Jesus said the Jews claimed the Father, he is our God, that Yeshua seeks the Glory from him, not from other men, and Yeshua himself said if you seek glory from men you get it, rather than Glory from God so do in secret and the one who sees in secret will reward you Matthew 6:4 - 4so that your giving may be in secret. And your Father, who sees what is done in secret, will reward you. / So when we move on here and we see Yeshua said I follow his word, so the old testament is HIS WORD which is the Father's word, the word God speaks is the Father not the Trinity but the Father his Word and the word is logon from logos, so is Yeshua saying I follow his myself, or I follow his Yeshua? so Yeshua follows himself?  or is it just simply The Fathers word, speech, utterance?  Simple.  So Jesus follows his word and he followed the entire Tanakh, he spoke the words of the Father why because only the Father is Yehovah not a trinity.  Let us continue in John 8:56-58 - 56 Your father Abraham was overjoyed that he would see My day, and he saw it and rejoiced.” 57 So the Jews said to Him, “You are not yet fifty years old, and You have seen Abraham?” 58 Jesus said to them, “Truly, truly I say to you, before Abraham [f]was born, [g]I am.” // So, Abraham saw his day, when?  When he said God will provide the lamb.  This is him being born of spirit from the dead in a figurative way with the full context of the chapter and other passages relating to Yeshua, it can not be saying Yeshua pre-existed him in physical creation, but has to be contextual to the spiritual birth from the Dead it is a figurative speech which is this - A figure of speech is a word or phrase that possesses a separate meaning from its literal definition. It can be a metaphor or simile designed to make a comparison. https://examples.yourdictionary.com/figure-of-speech-examples.html 

So Heterosis is: the figure of speech Heterosis. [1] Heterosis occurs with verbs, and is a form of exchange. It is the exchange of one form of the verb for another, one mood or tense for another, one degree for another, or one gender for a different gender. The exchange can be difficult to see because, for one thing, it occurs in the Hebrew or Greek verb. We must pay close attention to the context and scope of Scripture to make sure that we are understanding the change correctly. Nevertheless, there are some very clear examples in the Word of God.
Additionally - Another example of Heterosis might occur when a parent asks a son to take out the garbage. The son might look at the parent and say, “Done,” meaning that he will do it. The son does not know he is using the figure Heterosis (we also call this the idiom of the Prophetic Perfect)

So Heterosis is on site 2: The term heterosis was first proposed by G.H Shull in 1948 to replace the term heterozygosis. So what? Well, before that, the word “Heterosis” was used by E.W. Bullinger in his book, “Figures of Speech Used in the Bible,” which was first published in 1898. Bullinger’s use of this word has a completely different meaning than that which you might find if you do an internet search on “heterosis.”
Additionally: HETEROSIS – AKA THE PROPHETIC PERFECT TENSE - Here we come back to Bullinger’s definition of the term “Heterosis”: [The past tense is used instead of the future tense] when the speaker views the action as being as good as done. This is very common in the Divine prophetic utterances where, though the sense is literally future, it is regarded and spoken of as though it were already accomplished in the Divine purpose and determination. The figure is to show the absolute certainty of the things spoken of. – Bullinger, Figures of Speech Used in the Bible, Heterosis III-2
