You do realize the one blood is that of Christ don't you?
Paul said that we no longer know Christ after the flesh. He said that we are one
spirit in Christ.
As to the flesh are you saying God can't tell the difference in Asian, Blacks, Indians, or fair skinned peoples?
Your argument is circular. You ASSUME that a difference still remains and then you argue, "God can tell the difference." I am telling you that God
abolished the ethnic difference.
Again I ask, is there the possibility you're of Israel and just don't know it, and how would you discern that?
Thank you! Thank you! Thank you! No one can know if they are of Israel and they THEMSELVES must know it in order to claim their inheritance.
For the sake of argument let's do it your way. A great aunt of a homeless man may leave him an inheritance. But she doesn't know who he is. The homeless man also doesn't know about his great aunt. God knows who the man is. But if the man himself doesn't know who he is he will never claim his inheritance. The aunt may hire a private investigator to search him out and find him. The man is found and then informed that he has a great aunt that left him an inheritance. Then and
only then will the man claim what is his.
The Romans destroyed all the Jewish archives. There are no more geneaological records going back to the twelve tribal heads. So
no one can know if his lineage traces back to one of the twelve tribal heads. They cannot know if they are heirs.
And YOU cannot know that those who now occupy the so called promised land are descendants from the twelve tribal heads. So even if the distinction still remains as you suppose, God is NOT going to zap them all on the head and tell them. If that was His method, then He would not have given us the gospel to preach.
But God has solved it: "Believe on the Lord Jesus Christ and you will be saved," and, "You are all the children of God through faith in Christ Jesus. And if children, then
heirs according to the promise."
Those
who believe and
only those may know that they are heirs. It doesn't take a degree in rocket science.
