Our Father knows BA. He has established the bloodlines and He is not confused. He knows about all of us. In this age of grace, everyone should seek to be saved by the blood of the Lamb who is the Lord Jesus Christ, and to be found in Him at His coming.
The most important genealogy in the Bible is found in Matthew 1:1.
Mat 1:1 The book of the genealogy of Jesus Christ, the Son of David, the Son of Abraham:
Christ is the seed of the woman from Genesis 3:15, and the seed of Abraham in Genesis 12:3. Paul confirms this in Galatians 3:16.
After that point, a person's DNA is meaningless as revealed by the following text.
Mat 3:9 and
do not think to say to yourselves, 'We have Abraham as our father.' For I say to you that God is able to raise up children to Abraham from these stones.
(John the Baptist told his people to not say... "We are Abraham's seed.". However, many Christians today continue to say... "They are Abraham's seed.")
Joh 8:39
They answered and said to Him, "Abraham is our father." Jesus said to them,
"If you were Abraham's children, you would do the works of Abraham.
(Jesus made it plain to the Pharisees that being the seed of Abraham is not going to bring salvation.)
Joh 8:44
You are of your father the devil, and the desires of your father you want to do. He was a murderer from the beginning, and does not stand in the truth, because there is no truth in him. When he speaks a lie, he speaks from his own resources, for he is a liar and the father of it.
Rom 2:28 For
he is not a Jew who is one outwardly, nor
is circumcision that which
is outward in the flesh;
Rom 2:29 but
he is a Jew who is one inwardly; and circumcision
is that of the heart, in the Spirit, not in the letter; whose praise
is not from men but from God.
1Ti 1:4
nor give heed to fables and
endless genealogies, which cause disputes rather than godly edification which is in faith.
(A person's DNA sample does not now change their relationship with God.)
Grace is a result of the New Covenant promised to Israel and Judah in Jeremiah 31:31-34 and found fulfilled by the Blood of Christ in the following passage. The exact text from Jeremiah chapter 31 is quoted below and bracketed before and after with text revealing that Christ is now the mediator of this New Covenant, which has made the Old Covenant "obsolete".
Heb 8:6 But
now He has obtained a more excellent ministry, inasmuch as He is also Mediator of a better covenant, which was established on better promises.
Heb 8:7 For if that first
covenant had been faultless, then no place would have been sought for a second.
Heb 8:8 Because finding fault with them, He says: "BEHOLD, THE DAYS ARE COMING, SAYS THE LORD, WHEN
I WILL MAKE A NEW COVENANT WITH THE HOUSE OF ISRAEL AND WITH THE HOUSE OF JUDAH—
Heb 8:9 NOT ACCORDING TO THE COVENANT THAT I MADE WITH THEIR FATHERS IN THE DAY WHEN I TOOK THEM BY THE HAND TO LEAD THEM OUT OF THE LAND OF EGYPT; BECAUSE THEY DID NOT CONTINUE IN MY COVENANT, AND I DISREGARDED THEM, SAYS THE LORD.
Heb 8:10 FOR THIS IS THE COVENANT THAT I WILL MAKE WITH THE HOUSE OF ISRAEL AFTER THOSE DAYS, SAYS THE LORD: I WILL PUT MY LAWS IN THEIR MIND AND WRITE THEM ON THEIR HEARTS; AND I WILL BE THEIR GOD, AND THEY SHALL BE MY PEOPLE.
Heb 8:11 NONE OF THEM SHALL TEACH HIS NEIGHBOR, AND NONE HIS BROTHER, SAYING, 'KNOW THE LORD,' FOR ALL SHALL KNOW ME, FROM THE LEAST OF THEM TO THE GREATEST OF THEM.
Heb 8:12 FOR I WILL BE MERCIFUL TO THEIR UNRIGHTEOUSNESS, AND THEIR SINS AND THEIR LAWLESS DEEDS I WILL REMEMBER NO MORE."
Heb 8:13 In that He says,
"A NEW COVENANT," He has made the first obsolete. Now what is becoming obsolete and growing old is ready to vanish away.
The period of the New Covenant is "everlasting".
It does not end before the Second Coming of Christ.
Heb 13:20 Now may the God of peace who brought up
our Lord Jesus from the dead, that great Shepherd of the sheep, through the blood of the everlasting covenant,
