John 17:5 KJV — And now, O Father, glorify thou me with thine own self with the glory which I had with thee before the world was.
John 6:38 (NASB) “For I have come down from heaven, not to do My own will, but the will of Him who sent Me.
The above passages alone are sufficient to show Jesus’ pre-existence. Jesus Himself explicitly taught His own pre-existence as shown below.
No it doesn't, for actually what Jesus is praying for here, is that God would glorify both himself and Jesus together with the glory that he speaks of in the first verse from his hour of suffering and which Jesus had with the Father in the Father's foreknowledge of it before the world was and just as Peter also confirms as a second witness on this.
1 Peter 1:20 speaking of Jesus "who truly was foreknown (prognosis) before the world was but was in these last days manifested for you"
Peter wouldn't have used the word "prognosis" here if he believed that Jesus was God and pre existed his birth as God but he would have just stated that plainly instead but the word "prognosis" used by Peter here very clearly refers to God's foreknowledge of Jesus and that he was known by God before he existed the same way as Jeremiah was in Jeremiah 1:5 and David was in Psalm 139.
With the exception of the fact, that Jesus was the firstborn over them in God's foreknowledge and which by the way, Paul even reveals in Romans 8:29 below.
Romans 8:29, "For those whom he foreknew, them he also predestined to be conformed to the image of his (human Son) that he might be the firstborn among many (human) brethren".
By the way, this includes all the saints both OT and NT and therefore would include Abraham and John the Baptist also and you might want to consider this when you read verses like John 8:58 and John 1:15, for this is what they are truly revealing and not that Jesus pre existed Abraham and John as God.
For starters, John 1:15 makes it clear when John the Baptist said that Jesus was superior to him only because he was before him and not because he was his God
13And no man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven.
Notice, Jesus is speaking of himself not as the Son of God here but as the son of man and by the way, the words "which is in heaven" are not found in the best manuscripts and because they are not in all of them anyhow, they are questionable because of this fact.
33For the bread of God is he which cometh down from heaven, and giveth life unto the world.
Bread is a physical created substance and so was manna and Jesus even makes it clear in John 6 that it was his flesh that would give life and then he makes it clear also that the life was given unto him by God to give unto others and as per John 5:26 and John 6:57.
38For I came down from heaven, not to do mine own will, but the will of him that sent me.
Indeed, he was sent from the Father via the Holy Spirit and therefore came down from heaven as a brand new created male seed to replace Adam and his failure and that is why Paul in 1 Corinthians 15:45-47 calls him the second man and last Adam and we see more on this in Romans 5:12-22.
62What and if ye shall see the Son of man ascend up where he was before?
Yep, for he began in heaven as a new male seed and creation of God
23¶And he said unto them, Ye are from beneath; I am from above: ye are of this world; I am not of this world.
Yep they are from Adam and he wasn't but instead he was sent from heaven as a brand new human male seed and not tainted by Adam's failure and sin.
This is why in John 8:24, Jesus goes on to say, "for unless you believe that I am from above and not of this world" you will die in your sins, and which simply meant that he was the Messiah that God would send to die for the sins of all men and as Isaiah 53 and Psalm 22 states.
28I came forth from the Father, and am come into the world: again, I leave the world, and go to the Father.
Same argument as in my other replies.
If that doesn't convince you than we have The Lord saying He existed prior to Abraham’s birth (John 8:58–59) even though Abraham’s birth preceded Jesus’ own birth by many centuries! Several texts present Jesus as pre-existing with His Father (Romans 8:3; 1 John 1:2; Galatians 4:4). Several passages even identify Jesus as the Creator (John 1:2–3; Colossians 1:16–17; Hebrews 1:2).
Sorry but in John 8:56-58, Jesus was speaking about himself in a vision that Abraham received and by which he saw the day when Jesus would come and walk among the Jewish people his descendants and Jesus never moved from speaking about that vision, for the vision went back further than Abraham and in fact the first prophecy of his coming was in Genesis 3:15.
So what Jesus was speaking of, is the same thing that Paul wrote about in Romans 8:29, that Jesus was the firstborn in God's plan and predestination and in his foreknowledge and also the very image that all other saints would one day be conformed to as well.
Sorry but there is no scriptures that say "Jesus created all things" anywhere in the scriptures but only that "God created all things through and in him".
This simply means that in God created all things through his foreknowledge of Jesus and what he would do on the cross by his death and it was the only reason why God created anything that he did knowing that it would be ruined by sin, for Jesus would be the remedy to make it all worth creating.
For Jesus was the hope through and in which he went ahead and created all things knowing that it would be corrupted by sin and without which hope, God wouldn't have created any of it at all period.
