Marhig, even that passage you chose there is part of a set that shows equivalence. See Isaiah 45:23, Romans 14:11, and Philippians 2:10 individually and together. It's written inside and out.
Part 1, Isaiah
Isaiah 45:22-23 KJV
(22) Look unto me, and be ye saved, all the ends of the earth: for I am God, and there is none else.
(23) I have sworn by myself, the word is gone out of my mouth in righteousness, and shall not return, That unto me every knee shall bow, every tongue shall swear.
Question for Marhig, whom are we told to look to to be saved? When Moses raised the serpent upon the pole, whom did that serpent represent? This was Jesus, as in John 12:32, "And I, if I be lifted up from the earth, will draw all men unto me." We are told to look upon Jesus and be saved. Jesus was lifted up, and not another. Regardless, remember that the subject of Isaiah 45:23 is God, that "unto me [God] every knee shall bow."
Part 2, Romans
Romans 14:10-12 KJV
(10) But why dost thou judge thy brother? or why dost thou set at nought thy brother? for we shall all stand before the judgment seat of Christ.
(11) For it is written, As I live, saith the Lord, every knee shall bow to me, and every tongue shall confess to God.
(12) So then every one of us shall give account of himself to God.
Question for Marhig, to whom do we give account of ourselves? Jesus is the judge of the quick and the dead, and we stand before the judgment seat of Christ. Paul says we thus give account to God. We are judged by Jesus, we are not judged by the Father, yet it says we give account of ourselves to God. And by the way, note that "God" from the Old Testament is here now "saith the Lord." He's quoting Isaiah and he considers "God" and "the Lord" to be the same.
Part 3, Philippians
Philippians 2:10-11 KJV
(10) That at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth;
(11) And that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father.
Question for Marhig, did Paul make up something new, or is he quoting that passage in Isaiah again? The same passage that in the Old Testament where "God says unto me every knee shall bow" in Romans Paul interprets it as "the Lord saith unto me every knee shall bow" and in Philippiansthis same Paul understands that this is interchangeable with "unto Jesus every knee shall bow."
Marhig, I don't think Paul was a careless or uneducated writer. Yet he uses "God" and "Lord" and "Jesus" interchangeably when quoting the same Old Testament passage. People understand Jesus as their God because they read these scriptures.
And why not Marhig? In the aforementiond Isaiah 45:23 (and Jeremiah 22:5) God says that he swears by himself. He even refers to himself in the third person in passages like this in Zechariah:
Zechariah 3:2 KJV
(2) And the LORD said unto Satan, The LORD rebuke thee, O Satan; even the LORD that hath chosen Jerusalem rebuke thee: is not this a brand plucked out of the fire?
Even with my limited mortal self I will talk to myself: I think thoughts in my head and come up with answers, I send myself emails or write myself notes as reminders, and I don't have anything as complicated as being God and incarnate in flesh at the same time like God did. Your incredulous question isn't a valid evidence, actual bible statements are valid evidences.
How does he "live by his will and not by his own will?" Your statement is a contradiction. Regardless, Jesus lived by his Father's will, which is what you would expect if that were his true identity. I have multiple conflicting wills in myself (and Paul states the same in other scripture) yet we yield to our true selves. We are dealing with terms of expression. If Jesus lived by his own will and against his Father's will, then you would have a case saying that Jesus was not God. Not the other way around Marhig.
See all the above. If Jesus exercised will contrary to the Father, then he would not be God. If he could do things apart from the Father or against the Father, then he would not be God. And of course the Father is greater than he, just like my hand would defer to my head. They are both me, both ultimately the same person.
Jesus is the living God, which is why he drops the subtle approach entirely by the time we reach the book of Revelation. "I am the beginning and the end" he says. If you don't know the significance of that title, read the book of Isaiah. Word search that phrase, you'll find it.
