You don't say what points of the above relate to the points I made. So I can only make general comments in return.
1. You claim Jesus wasn't in the OT but he was. Jesus is the Word.
In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God; all things were made through him, and without him was not anything made that was made…..
….And the Word became flesh and dwelt among us, full of grace and truth; we have beheld his glory, glory as of the only Son from the Father. (John 1:1-3, 14)
In the beginning God created the heavens and the earth. (Gen 1:1)
Jesus was there at the beginning
2. You claim that the Holy Spirit only speaks scripture and quote Jn 14:26
But the Counselor, the Holy Spirit, whom the Father will send in my name, he will teach you all things, and bring to your remembrance all that I have said to you.
But not everything that Jesus spoke is recorded in scripture.
But there are also many other things which Jesus did; were every one of them to be written, I suppose that the world itself could not contain the books that would be written. (John 21:25)
So how could the Holy Spirit remind the apostles "all that I have said to you" if not all is recorded in scripture?
After his resurrection Jesus spent 40 days with his disciples until his ascension. Unless you think he spent that time chatting about the old days we must presume he was teaching them and giving final instructions of their mission.
Of that time very little is recorded. So how can the Holy Spirirt remind them of those teachings if he only speaks scripture?
Moreover, according to Wikipedia, regarding John's gospel "Most scholars estimate the final form of the text to be around AD 90–110." So if the Holy Spirit only spoke scripture he could not remind the apostles of some of the things that Jesus said until 60+ years after Jesus' death.
3. You quote John 16:13
When the Spirit of truth comes, he will guide you into all the truth; for he will not speak on his own authority, but whatever he hears he will speak, and he will declare to you the things that are to come.
This is about guiding the apostles in the future as new situation arise. But if the Holy Spirit only speaks scripture how could he guide the apostles into all truth in new situations? The Holy Spirit cannot speak anything new if he can only speak what has already been written.
How can the Holy Spirit "declare to you the things that are to come" if the can only quote the past?
Trinity Is A Strong Delusion
So I might just as well show it to you. God said if you dont have a love of the truth He would put strong delusions in scripture that you would fall for. He did. Now there are verses that can be taken out of context to form a deceiving belief. The trinity has done this. Trinity isnt in the bible, deity isnt in the bible. I refuted all the evidence they could come up with in the ninties. So now they step outside of the scriptures to explain something that isnt in scripture the trinity. They explain the trinity with eggs, water, door nobs, human families. They break every rule that a believer must follow to find the truth. Dont think beyond what is written, and dont add one thing to the verses or take one thing away from the verses.
1 Cor 4:6
6 Now these things, brethren, I have figuratively transferred to myself and Apollos for your sakes, that you may learn in us not to think beyond what is written, that none of you may be puffed up on behalf of one against the other.
(NKJ)
Rev 22:18-19
18 For I testify to everyone who hears the words of the prophecy of this book: If anyone adds to these things, God will add to him the plagues that are written in this book;
19 and if anyone takes away from the words of the book of this prophecy, God shall take away his part from the Book of Life, from the holy city, and from the things which are written in this book.
(NKJ)
xxx Once they get you hooked, they start telling you no one can truly understand the trinity, and no one will truly understand it until after we leave this world. That is not what scripture teaches. Scripture teaches us there is nothing hidden that will not be revealed. The trinity plants all these doubts in your mind so you won't go looking for the truth.
Mark 4:22-23
22 "For there is nothing hidden which will not be revealed, nor has anything been kept secret but that it should come to light.
23 "If anyone has ears to hear, let him hear."
(NKJ)
xxx They want you to worship God through your imagination. And if you want to find the Holy Spirit you must get rid of your imagination. The only power we have against deception is the Word of God. The trinitarians dont want you in the Word.
2 Cor 10:4-5
4 (For the weapons of our warfare are not carnal, but mighty through God to the pulling down of strong holds;)
5 Casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ;
(KJV)
xxx Trinitarians are the blind leading the blind.
Luke 6:39
39 And He spoke a parable to them: "Can the blind lead the blind? Will they not both fall into the ditch?
(NKJ)
II Th 2:10-12
10 and with all unrighteous deception among those who perish, because they did not receive the love of the truth, that they might be saved.
11 And for this reason God will send them strong delusion, that they should believe the lie,
12 that they all may be condemned who did not believe the truth but had pleasure in unrighteousness.
(NKJ)
2 Pet 3:16
16 as also in all his epistles, speaking in them of these things, in which are some things hard to understand, which untaught and unstable people twist to their own destruction, as they do also the rest of the Scriptures.
(NKJ)
xxx The Word abiding in you from the Holy Spirit is the only true success spiritually. The Holy Spirit is the only guarantee in the whole bible.
[Jhn 5:38–44
[38] "But you do not have His word abiding in you, because whom He sent, Him you do not believe.
[39] "You search the Scriptures, for in them you think you have eternal life; and these are they which testify of Me.
[40] "But you are not willing to come to Me that you may have life.
[41] "I do not receive honor from men.
[42] "But I know you, that you do not have the love of God in you.
[43] "I have come in My Father's name, and you do not receive Me; if another comes in his own name, him you will receive.
[44] "How can you believe, who receive honor from one another, and do not seek the honor that [comes] from the only God?
xxx The Holy Spirit can only bring to remembrance what Jesus has already said. The verses . And only the verses that you have believed.
[Jhn 14:26
[26] "But the Helper, the Holy Spirit, whom the Father will send in My name, He will teach you all things, and bring to your remembrance all things that I said to you.
