Wow! You have the God/man relationship down pat in your mind don't you.
The Son, the second Person of the Trinity, left the body He temporarily inhabited on Earth, but His divine nature did not die, nor could it.
Now, you like asking questions but you don't answer mine. If Jesus is God and God is one who was Jesus talking to when on the cross he said "My God, my God, why have you forsaken me"?
No I don’t have it down pat. That’s why I have so many questions. And it is by no means intended to be an inquisition. Your response: “The Son, the second Person of the Trinity, left the body He temporarily inhabited on Earth, but His divine nature did not die, nor could it,” gives me something to ponder. It was necessary for Christ to suffer these things and enter into His glory, but maybe it was sufficient for Christ to die in his human form to redeem us from our sins.
I did answer your question about Psalm 22. You said please explain. After offering suggestions, I concluded by saying I don’t know. As to who He was talking to, I have given that some thought in the past. Was it to the Father, to the crowd, to anyone? Maybe in His humanity He was just crying out in anguish. I really don’t know that answer, either.
