Jesus is God. He has existed thru all eternity, therefore his existence does not depend on whether God wanted or needed a son, he wasnt created, hes always existed
Therefore your arguments are meaningless.
Doesn't Psalm [90v2] say God is from everlasting. Meaning no beginning.
Only God was before the beginning.
The word 'father' means life giver. Jesus calls God as his Father [Life Giver]
Even the resurrected heavenly Jesus still thinks he has a God over him at Revelation 3v12.
The resurrected heavenly Jesus still considers himself as the Son of God at Rev. 2v18.
If Jesus always existed why does Jesus consider himself as the beginning of the creation by God at Rev. 3v14 B ?
