I"ll answer your question. Do I have God's Spirit inside me? Of course. Scripture tells us that.
Ok, next. God "came as a son". That tells me that God is now two. The God that is still in heaven that Jesus prays to and the God that "changed" into a man. So now we have two Gods. Wow, I'll tell ya, this is something that I'll never believe in!! Sorry my friend....
Why cant you believe that Jesus is the son of God? If God came to earth as a man, why the role playing of father and son? Couldnt God just say, ok, I'm coming down to earth as a god. And thats it. Why do we have this father and son thing? Ever think of that? God is the Father. Jesus is the son. That's what I read.
Look at the OT. They were told that the "coming Messiah" would be a man from David's line. Psalms 22, 2 Sam 7, Isaiah 53, etc, etc..... Sorry, but I completely dont see what your seeing at all.
