Rella, you mention in your post the importance of genealogy. If you believe, as many do, that we all came from Adam and Eve, then all of mankind would trace back to them eventually. In other words, all mankind would be the "seed" of the woman Eve. But, Scripture says that "Eve is the mother of all those who live." From what I understand, the "seed" is the word of God( the Golden Rule) which was what Jesus was teaching. It is the word of the Spirit that gives life to all who obey. This word came from Adam and Eve who handed them down to their children.
I am not sure I fully understand your question.
I would first have to ask you if you do not believe we all came from Adam and Eve, how would that even be possible?
As my thoughts run...
If you believe that God formed Adam from the earth of the ground and then made Eve from one of Adams ribs (or even if you are among those who do not accept this idea of how they came into being) then all future human life would have had its beginning there.
After the flood, ( and if you are among those who do not believe in the flood ) I will amend this to say after Noah, Shem, Ham Japheth and their wives left the ark they proceeded to populate the world again.
If the entire ark and world wide flood story is a myth inspired by God to be placed in His Holy Words.... (perhaps for a good bedtime story?) in any event, yes, those people who begat , and begat and are still begatting to this very day down through the centuries are descended from Adam as there was no other human being around until Eve, and then their children.
(This is no place or forum for you if you believe Adam was not the first man, as others do, so we will continue with this idea that mankind as accepted all these generations)
The inportance of genealogy
See Genesis 5
There are 10 generations for Noah to Adam. Just about 1100 years.
Genesis 5 starts out with
1 This is the book of the genealogy of Adam. In the day that God created man, He made him in the likeness of God.
Inspired words from God to the author.
Because it was important.
Mathew 1 tells us Jesus' lineage.... by way of Joseph. As Joseph was not Jesus' biological father is this in error? No.
Mathew 1 starts out with
1.The book of the genealogy of Jesus Christ, the Son of David, the Son of Abraham:
and vs 16
16And Jacob begot Joseph the husband of Mary, of whom was born Jesus who is called Christ.
Even in Luke we have the following ( see this chart for clarity)
And it seemingly points to Joseph as being the link to David... even not being a blood relative.....
And interesting reading from scripture is in Jerimiah 22: 24-30
24 “As I live,” says the Lord, “though [a]Coniah the son of Jehoiakim, king of Judah, were the signet on My right hand, yet I would pluck you off;
25 and I will give you into the hand of those who seek your life, and into the hand of those whose face you fear—the hand of Nebuchadnezzar king of Babylon and the hand of the [c]Chaldeans.
26 So I will cast you out, and your mother who bore you, into another country where you were not born; and there you shall die.
27 But to the land to which they desire to return, there they shall not return.
28 “Is this man [d]Coniah a despised, broken idol—
A vessel in which is no pleasure?
Why are they cast out, he and his descendants,
And cast into a land which they do not know?
29 O earth, earth, earth,
Hear the word of the Lord!
30 Thus says the Lord:
‘Write this man down as childless,
A man who shall not prosper in his days;
For none of his descendants shall prosper,
Sitting on the throne of David,
And ruling anymore in Judah.’ ”
Pay attention... there may be a test
This passage says that no descendant of Jeconiah would have the right to the throne of David.
Until Jeremiah, the first requirement for messianic lineage was to be of the house of David.
So not only must the Messiah come from the line of David.... He must also be apart from Jeconiah.
Yet, as we read in Matthew’s genealogy, Joseph is of the lineage of Jeconiah—meaning, none of his descendants could sit on David’s throne.
So then how could Jesus be the Messiah, if the Messiah must come from the line of David, but also not be of the line of Jeconiah?
Wait.... it gets truly interesting here....
Remember: Mary was a virgin when she concieve Jesus by the Holy Spirit. That would make Jesus, at best, Joseph's adopted son, while being Mary's biological son.
So how does this explain Jesus being a descendant of David?
Remember King David had more than one son. One of them was Nathan. None of Nathan's descendants had any "Jeconiah-like" curses.... and Mary was a descendant of Nathan.
It does get more involved then this but you were not talking about Jesus lineage, I just got carried away.
And that was to make a point that GOD inspired all that to be written in the scriptures we call the Holy Canon so God really believes genealogy to be important.
