If Jesus pre-existed as God then that would contradict Scripture and mean that Jesus changed. Jesus is a man, was always a man, will always be a man. No way around this.
Hebrews 13 (NIV)
8Jesus Christ is the same yesterday and today and forever.
Revelation 1:8 isn't about Jesus being the Almighty. If you will check the context, Revelation 1:4-8, you should see the following:
Jesus isn't "Him who is and who was and who is to come" therefore he isn't the Lord God Almighty. Case closed.
Revelation 1
4John, to the seven churches which are in Asia:
Grace to you and peace
from Him who is and who was and who is to come, and from the seven Spirits who are before His throne,
5and from Jesus Christ, the faithful witness, the firstborn from the dead, and the ruler over the kings of the earth.
To Him who loved us and washed us from our sins in His own blood,
6and has made us
[c]kings and priests to His God and Father, to Him
be glory and dominion forever and ever. Amen.
7Behold, He is coming with clouds, and every eye will see Him, even they who pierced Him. And all the tribes of the earth will mourn because of Him. Even so, Amen.
8“I am the Alpha and the Omega,
the Beginning and
the End,” says
the Lord, “who is and who was and who is to come, the Almighty.”
Those don't say Jesus is himself eternal life, but rather eternal life is something that can be found in him. Furthermore, Jesus didn't inherently have life in himself or the authority to give eternal life, but rather those are privileges granted to him by the Father. The Father is the Only True God.
John 17 (NIV)
2For
you granted him authority over all people that he might give eternal life to all those you have given him.
John 5 (NIV)
26For as the Father has life in himself, so
he has granted the Son also to have life in himself.
Eternal life was something revealed by or manifested in Jesus. The Word of life, or eternal life, is a thing, not a person. It's something someone can have by knowing the Only True God and Jesus (John 17:3)
1 John 1 (NIV)
1That which was from the beginning, which we have heard, which we have seen with our own eyes, which we have gazed upon and touched with our own hands—
this is the Word of life. 2And this is the life that was revealed; we have seen it and testified to it, and we proclaim to you the eternal life that was with the Father and was revealed to us.
That is not Jesus in Rev. 1:8. Please see what I said above.
Jesus did not create all things. The grammar of John 1:2,3 proves that the God the Word was with is the Creator, not the Word being the Creator.
John 1 (NIV)
2He was
with God in the beginning.
3Through him all things were made; without him nothing was made that has been made.
This supports that fact that ALL THINGS are from the Father, not Jesus.
In Psalm 45:6, this same line of text appears, and it's used to refer to a human with a queen. When the writer of Hebrews transferred to concept to Jesus it was not their intention to say Jesus is God, but since capitalization didn't exist in the Hebrew and Greek, just making it capitalized gives the wrong impression.
Scripture says Jesus and "men" were given this authority to forgive sins. Means Jesus and the other men didn't inherently have this power, but it was given to them. Means it was not a Jesus exclusive.
Matthew 9 (KJV)
6But that ye may know that
the Son of man hath power on earth to forgive sins, (then saith he to the sick of the palsy,) Arise, take up thy bed, and go unto thine house.
7And he arose, and departed to his house.
8But when the multitudes saw
it, they marvelled, and
glorified God, which had given such power unto men.
Being bowed down to as the son of God doesn't mean Jesus accepted worship as God. Being Son of God doesn't mean Jesus is God. There are many sons of God who are not God. Many examples of kings or people of status accepting or giving worship in the Bible without it meaning they were accepting it as God.
Jesus is never given the kind of spirit and truth worship reserved only for God in Scripture.
True worshippers only worship the Father. This proves Jesus is not God.
John 4 (NIV)
23Yet a time is coming and has now come when the t
rue worshipers will worship the Father in the Spirit and in truth, for they are the kind of worshipers the Father seeks.
24God is spirit, and his worshipers must worship in the Spirit and in truth.”
Hebrews 1:6 proves Jesus isn't YHWH. YHWH said He is the only God.
Isaiah 45 (NIV)
5I am the Lord, and there is no other;
apart from me there is no God.
I will strengthen you,
though you have not acknowledged me,
Scripture already teaches what is in the heart of man. This is something everyone can know.
Jeremiah 17 (NIV)
9The heart is deceitful above all things
and beyond cure.
Who can understand it?
This doesn't teach that Jesus is omnipresent. Jesus will have a physical return to earth in the future. He isn't here yet.
Revelation 1 (NIV)
7“Look, he is coming with the clouds,”
and “every eye will see him,
even those who pierced him”;
and all peoples on earth “will mourn because of him.”
The Father gave Jesus that authority so he didn't inherently have it.
John 17 (NIV)
2For
you granted him authority over all people that he might give eternal life to all those you have given him.
Jesus does not fit the definitions of God.
There are dozens of names, titles, qualities, and statuses that Jesus doesn't share with God.
At your service,
Brother Runningman, One God and Father of all, over all, the only true God.
