I've had this discussion, and studied the topic, for a number of years. You could say I'm familiar with the material.
Jeremiah wrote that YHWH is the God of all flesh, and therefore, when Jesus took on flesh, He took that on also. He joined us in our fleshy lives in all respects except without sin. Yet still He submitted to the Father as we are all to do. It's like He told John. He didn't need to be baptized, that was for the remission of sin, and He had no sin. Yet still He submitted to being baptized. He did everything we were supposed to do.
But again, from Philippians,
Philippians 2:6-8 KJV
6) Who, being in the form of God, thought it not robbery to be equal with God:
7) But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men:
8) And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross.
I'm not talking about "to be equal with God". There's quite the discussion about those words, but no, I'm looking at:
made himself of no reputation
took upon him the form of a servant
being found in fashion as a man, he humbled himself
Each of these three statements show transition. Transition involves both a former and latter state of being. And of course this is what that means to me:
God the Mighty and Exalted One . . . made Himself of no reputation.
God, the King of Kings and Lord of Lords . . . took upon Him the form of a servant.
God, the Creator of all, being found in fashion as a man, submitted Himself to that lowly estate.
Now, whether you would frame this as I do, probably not, right? However . . . Where was Jesus before He was a child in Mary's womb? And Who was He? We know Him, we've seen Him in the Bible.
No one has seen the Father at any time. Who did Abraham serve a meal to?
Genesis 18:1-5 KJV
1) And the YHWH appeared unto him in the plains of Mamre: and he sat in the tent door in the heat of the day;
2) And he lift up his eyes and looked, and, lo, three men stood by him: and when he saw them, he ran to meet them from the tent door, and bowed himself toward the ground,
3) And said, My Lord, if now I have found favour in thy sight, pass not away, I pray thee, from thy servant:
4) Let a little water, I pray you, be fetched, and wash your feet, and rest yourselves under the tree:
5) And I will fetch a morsel of bread, and comfort ye your hearts; after that ye shall pass on: for therefore are ye come to your servant. And they said, So do, as thou hast said.
Much love!
