Ok, I can accept what you are saying here, but then it leads me to ask: how then did the fullness of the God head dwell bodily in Him if He was not in possession of all His godly powers? How can this be fullness if He didn't possess them? The only way I see to resolve this would be to say that Jesus did possess all of His godly powers but chose to use none of them while walking on the earth. It is like a man that possess great physical strength or fighting ability but chooses not to use it in a confrontation. In affect, it would put that man on equal footing as someone that did not possess these abilities.
For me it is a difference between a description and a definition.
Omni-powers
describe some aspects of god-hood that separates God from His creation. That is not to say that god-hood is
defined by those aspects, so the fullness of the God-head does not require Jesus to have those abilities at all times.
Jesus's essence as God is his Holiness and His One-ness with the Father and The Spirit.
Here, several posts has referred to God's DNA. We know that we are not really talking about physical deoxyribonucleic acid, but the essence that Jesus shares with the Father. (I was going to say 'derives' from the father, but that might be taken to imply that the Father had to exist before the Son).
The
powers of the son may proceed from His
essence as God, but his essence as God is not dependent upon those powers.
In my posts, I have tried to avoid stating flatly that Jesus did not have those powers available to Him, in His own right while He was on Earth. I truly don't wish to ponder that too closely (particularly in terms of his human development). To me, both his divinity (holiness, oneness, same essence as the other two) and His humanity are important. I really do not want to draw a fine line separating two natures (which I think would be a wrong way to approach Him).
As an aside: A few years ago, I was looking through my copy of Gray's Anatomy. I noticed a couple of places where my body, as I was born and developed do not match. Later medical procedures further changed me. If we take that book as description than I am just an uninteresting deviation. If you take it as defining human than I am not a human.
If you take the powers as descriptive of the god-hood, you are left with one view, but if you take those as defining god-hood, you are left with a very different view.
