What does that have to do with this discussion? Nothing
It is actually an important aspect of the discussion.
What separates Christ the Man from all other men, including Adam, is that at no time was He separated from God.
Adam enjoyed fellowship with God, which may or may not be likened to our fellowship with Him when we are redeemed, immersed into God in eternal union, and thus born again. I lean to the to the position that Adam was not in eternal union with God, but rather that he was more likely filled with the Spirit as was the norm in the Old Testament.
When Adam sinned, which was a willful violation of the direct command of God, he lost that communion with God and access to the Tree of Life, thus death entered the world, and consequently all of his offspring are born in that state.
Christ's conception and birth, on the other hand, was not due to procreation, but the flesh He took upon Himself was created in the womb of Mary, and again, the one thing that distinguishes Him from all other men is that He never shed His Deity, and was thus never separated from God.
That is man's condition, and the reason he sins. I think Martin put it best:
in our natural state are 'non posse non peccare'-- not able not to sin.
And the reason is because we are conceived and born separated from God. "Not sinning" requires the intevention of God.
Dead in our sin and transgression? Yes
Yes. That too is an important element of the discussion, because no man has life except he eat of Christ's flesh and drink His blood, which is to say...believes on Him in His capacity as Risen Savior. The True Bread He gave was His flesh, or in other words, His offering of Himself in our stead, taking upon Himself our penalty for sin, which is death.
Not spiritual death, because Christ did not die spiritually to achieve Atonement. He died physically.
Dead in Adams sin and transgression? No
Dead
because of Adam's sin.
Is Jesus's divine nature simply a bent or disposition toward Divine things? Or is his divine nature the essence of his being?
Agreed, He did not shed His Divine Nature. What He did was veil that Nature in flesh, thus taking on the limitations imposed by the flesh.
God bless.
