When you see verses like "and the Holy Spirit descended on him in bodily form like a dove", it makes it seem real contrived to say that Jesus descended upon himself.
John 14:10 Do you not believe that I am in the Father and the Father in me? The words that I say to you I do not speak on my own authority; but the Father who dwells in me does his works.
Let's see. The Father dwells in heaven. Yet the Father dwelt in Jesus. How did He do that? Wasn't that personal dwelling of the Father within Jesus the Spirit of God, the Spirit of the Father?
Likewise, was not the Holy Spirit that descended upon Jesus, none other than the Spirit of the Father?
It seems that when Jesus lived here on earth, His Spirit was confined to His body. After He was raised, He could extend it anywhere in the universe.
I still see the Deity as comprising of exactly two Divine Individuals.
