Those scriptures i gave you are 100% irrefutably directly connected to understanding who the "sons of God" were/are in Genesis ch6
How are they connected? They don't share a common theme or a common subject matter. The ONLY thing they have in common are three words "sons of God."
So also is Romans 8: 9-11"though the body is dead because of sin, yet the spirit is alive because of righteousness"
AND
1 Cor ch15 - Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; nor does corruption inherit incorruption. Behold, I tell you a mystery: We shall not all sleep, but we shall all be changed— in a moment, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, and the dead will be raised incorruptible, and we shall be changed.
For this corruptible must put on incorruption, and this mortal must put on immortality.
Our flesh bodies were not Born-Again, only our spirit.
Spirits are not born again. People are born again. Don't fall for the fallacious spirit/flesh dichotomy.
This you said is true: "But this is not the final state of the man in Christ."
Focus on the TRUTH = Luke 20:34-36
Jesus answered and said to them, “The sons of this age marry and are given in marriage.
But those who are counted worthy to attain that age, and the resurrection from the dead, neither marry nor are given in marriage;
nor can they die anymore, for they are equal to the angels and are sons of God, being sons of the resurrection.
There are two problems with your analysis in my view: 1) The New Testament's use of the phrase "sons of" and answering the wrong question.
"Sons of"
In the New Testament, the phrase "sons of" has the figurative meaning: "characteristic of." For instance, Mark records the calling of the Twelve and in that passage we read that Jesus gave nicknames to the sons of Zebedee, "sons of thunder." In other words, James and John were like thunder in some way.
In Luke 20:34-36, Jesus is comparing TWO groups: 1)
sons of this age and 2)
sons of the resurrection. The sons of this age are those living in this age, with all of the attributes and limitations of this age. The Sons of the resurrection have new and different attributes and have some of the limitations removed.
Jesus isn't saying that the sons of the resurrection are equal to angels. He is saying that the sons of the resurrection they will share at least one situation and one attribute in common with the angels. Situationally, the sons of the resurrection will not marry or be given in marriage, just like the angels. And with regard to having a new attribute; The sons of the resurrection can never die anymore, just like the angels.
Answering the wrong question:
With regard to the nature of humanity, we ask two different fundamental questions, 1)
who are we, and 2)
what are we. If you are asking me
what I am, I will list my attributes such as: sex, age, height, species, etc. If you are asking me
who I am, I will list items that situate me in time and history and why I am distinct from other human beings: name, family linage, address, education, CV, occupation, work history and etc.
Now, consider the investigation process as we seek to understand what Genesis 6 means by "the sons of God." What question are we asking? Who are they? or What are they? Deciding which question is relevant is fundamental to our understanding of the passage. Is Moses telling us
who these people are or is he telling us
what these people are?
Suppose Moses was answer the question, "what are they?"
What:
Sons of God = angelic beings
Daughters of men = human beings.
But suppose Moses was answering the question, "who are they"?
Who:
Sons of God = royalty
Daughters of men = common
Hopefully you can see the distinction and why it matters whether Moses is answering "who" or "what."
Is he concerned with their metaphysical state, i.e. angel vs. human, or is he concerned with their status among humans, i.e. royalty vs. common?
Those who say that the "sons of God" are angelic beings are answering the question, "What are they?" Son = Angel = metaphysical state = a state of being. But what if that is the wrong question to ask?
Focus on the TRUTH = 1 John 3:1-3
Behold, what manner of love the Father hath bestowed upon us, that we should be called the sons of God: therefore the world knoweth us not, because it knew him not. Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is. And every man that hath this hope in him purifieth himself, even as he is pure.
If you deny or misalign scripture, you will come to your own understanding (PhD) and FAIL to SEE what has been Said.
Again, what question is John addressing? Is John saying that we are now Angelic beings? I don't think he is.
