The OP gets really tricky when we get to human nature, Original Sin, and the hypostatic union. That's what I don't want to touch
Right. I don't know how to navigate those difficulties. But, as
@Pavel Mosko pointed out earlier, it can tend towards Apollinarianism to exempt him the internal experiences common to other humans, perhaps.
Apart from these matters, which are surely important (???), what if we just look at Jesus's life from a few things we can see:
NKJ Isaiah 50:4-6
"The Lord GOD has given Me The tongue of the learned, That I should know how to speak A word in season to him who is weary.
He awakens Me morning by morning, He awakens My ear To hear as the learned. 5
The Lord GOD has opened My ear; And I was not rebellious, Nor did I turn away. 6 I gave My back to those who struck Me, And My cheeks to those who plucked out the beard; I did not hide My face from shame and spitting.
NKJ Luke 2:40 And
the Child grew and became strong in spirit, filled with wisdom; and the grace of God was upon Him....42 And
when He was twelve years old, they went up to Jerusalem according to the custom of the feast. 43 When they had finished the days, as they returned,
the Boy Jesus lingered behind in Jerusalem. And Joseph and His mother did not know it;...46 Now so it was that after three days
they found Him in the temple, sitting in the midst of the teachers, both listening to them and asking them questions. 47 And
all who heard Him were astonished at His understanding and answers... 49 And He said to them, "Why did you seek Me?
Did you not know that I must be (speaks of necessity) about My Father's business?"
NKJ John 3:34 "For
He whom God has sent speaks the words of God, for God does not give the Spirit by measure.
NKJ John 8:26 "I have many things to say and to judge concerning you, but He who sent Me is true; and
I speak to the world those things which I heard from Him." 27 They did not understand that He spoke to them of the Father. 28 Then Jesus said to them, "When you lift up the Son of Man, then you will know that I am He, and that I do nothing of Myself; but
as My Father taught Me, I speak these things. 29 "And He who sent Me is with Me. The Father has not left Me alone, for
I always do those things that please Him...."
I speak what I have seen with My Father, and you do what you have seen with your father."
Point being, what an extraordinary upbringing Jesus had and with the Spirit promised to Him as Abraham's Seed. Taught by God. The strong spirit/filled with wisdom at age 12. The resolve at 12 to speak of the necessity of being about His Father's business. He speaks the Father's words and always does what pleases the Father. The knowledge and resolve to handle the adversary's tests in the wilderness. The resolve to handle the cross in obedience to our Father.
I've studied the matters you speak of. I sometimes wonder why we don't just focus on how He was brought up, taught, trained, and the knowledge and resolve He had developed within Him to be about His Father's will above anything and everything else. The thought of ever going against His Father was just foreign to Him.
In concept this is a similar upbringing we have in Christ by His Spirit. The older I get and the more time I redeem learning and pondering these things, the more I understand the mindset of desiring never to be out of our Father's will and only do and say what pleases Him. What's the point of existence if not this?
Not able to sin. Able not to sin. I don't know if I really care anymore. Didn't sin. Learned obedience. Saving us from our sins, so we can live a life to God. We don't know who and what we are yet, but when we see Him we'll be like Him.... Sin's disgusting. Functioning at such low capacities we were not designed to have to function at is horrible. Watching this world destroy itself is tragic. Learning of the mindset developed in our First-Born Brother by our Father and how He always remained in our Father's love is amazing. I think we self-limit how much we - a new creation in Christ Jesus - have available to us.
