Yes I agree the couple verses tbat state a trinity concept are grown and then people try to explain what it means rather then realizing the entire Bible explains what it means and who it’s talking about
“Who is the image of the invisible God, the firstborn of every creature: ( see he’s God the creator and also became the first creature one and the same expanding into his own creation himself in order to redeem it from sin and death )
for by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him: and he is before all things, and by him all things consist. ( this can only be speaking if God himself created by him ( father ) for him ( son )
And he is the head of the body, the church: who is the beginning, the firstborn from the dead; that in all things he might have the preeminence. For it pleased the Father that in him should all fulness dwell;”
Colossians 1:15-19 KJV
before jesus was born
“The heaven, even the heavens, are the LORD's:
But the earth hath he given to the children of men.”
Psalm 115:16 KJV

“Jesus knowing that the Father had given all things into his hands, and that he was come from God, and went to God;”
John 13:3 KJV

“And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth.
Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.”
Matthew 28:18-20
He has to become a man because earth was given to man and he doesn’t go back on his word so he fulfilled the requirements of man himself becoming one of us the hiers of creation from the beginning
