Jesus has always been the Son. The Father has always been His God.
Much of about the Son predates the Son of Man.
This is truth and was written for future generations. We will live because of Jesus. The life in Jesus is the Father. Jesus calls the Father truthfully as the only true God.
Just as the living Father sent me and I live because of the Father, so the one who feeds on me will live because of me.
I think we agree on many things about the Son.
I still am not clear about your view of the most important aspect of His identity as God; the Lord God Almighty.
Do you believe Jesus is Lord; YHWH, the Lord God Almighty?
