Greetings StillSVoice.
I see you have a keen eye for bent things..
Quote: No; while He may assign specific tasks to various angels (to run His errands, so to speak),
True...but it's not as though God has not the power to do the things Himself as to these specific tasks assigned.
But it seems He has chosen to assign things as if by design.
quote: God does not share/delegate power.
While He might not share/delegate power...yet in the purpose/pleasure of His plan, He gives authority to exercise His power.
And in this grand scheme of things God has (by design) needs. Such as a Messiah.
Therefore, the Messiah shares in value with God. For God cannot deliver man or advance man from his fallen condition without The Man (Messiah).
Without the Man...there is no remissiion/forgiveness of sin. There must be shedding of blood as you well know.
This is why under the new covenant (as I contend) being an oneness advocate of God...understand Philipians 2 to mean that the man Christ Jesus did not think he was stealing anything away from God. In fact, saw his role in the plan/design of God as being (as a man) of equal value. Without him there is no salvation, no restoration, no restitution, etc.
So, God will/has exalted (the Man) -to the right hand of God- the place of authority.
If I'm not right about Jesus being the Messiah, then when he comes, he will be highly exalted in the manner aforementioned.
Angels would not be able to run these errands for God so to speak ...
only a man.
And while, maybe, not sharring His power, He would yet share Himself in a manner that would allow man to take dominion of the earth once again.
He breathed Himself into Adam. Why not breath Himself into Messiah (Emanuel)?
Thatzall..
