John 3:13:
Everyone came from Heaven. It is saying everyone has come with the Word Of God who is in heaven, the commandments. Which is why Nicodemus is asking, and Jesus says how do you not know this. They were from Heaven, like SYMBOLICALLY how God is in Heaven, we were sent from God to spread the commandments. Jesus himself told him how you do not know this, meaning he also was from Heaven. Now if you wanna put it into that interpretation, then that means Nicodemus was also in Heaven with Jesus, so look at it, and you will see that he is not LITERALLY from Heaven.
John 8:58:
I AM, does not mean he was born before Abraham. Once again, it means that before Abraham was even created. His Word, which is Word Of God was there. God was there before Abraham, he never says that he was there before Abraham chronilogically but that God, the Word was. Which he was spreading. I AM is used as an identification of what he was, a prophet sent as we can see in
Exodus 3:14 It is God essentially.
John 1:1:
Same thing. Word is God. The Word was with God, whom Jesus was sent to spread the Word. For certain the Word is God, not Jesus.
John 17:5:
He never said he was there before World was there. The Glory was there before it began meaning God once again.
The verses before say whom God has sent. So, another thing is he never claimed divinity, just saying.
John 6:62:
Same, thing. He was with God, the commandment, as God prescribed.
John 6:38:
Same thing.
