You probably have a good reason to write what you did, and in all but one point I agree. But what is the difference between ...
"God continued His plan through Noah" (Corban),
and
"Noah would be instrumental in the descent of Jesus of Nazareth from Adam" (Nehemiah6)?
First, it seems like semantics to me. Second, the lineage from Noah is vitally important because Noah's "generations were perfect". That is, the way he was generated, and what he generated, were perfect, showing that he was not involved in the lineage of angels (the context). Satan's attack is always directed at the seed of the woman by murder, war, famine, mating with angels, mating with man-KIND (homosexuality), bestiality and "forbidding marriage".
The point I question is that being the "rightful heir to the throne of David" achieves nothing for the Nations. Israel and the Nations are mortal enemies. And it helps nothing to point out that Christ is the "seed of the woman" because (i) that woman, Eve, was not an Israelite, and (ii) Luke traces His lineage to Adam - also not an Israelite. Of much more profit to the Nations is "seed of Abraham", for to Abraham's seed is the WORLD promised (Rom.4:13). Abraham, like Adam, was a Gentile - a Syrian.
Not many understand this principle. It gives us the answer to all the bloodshed and wars throughout the Old Testament. It gives us the answer to virtually every Old Testament story. Satan attacking the seed line, and God doing whatever it took to preserve the seed line.
