The point of my question is this:
Jesus called us the lost sheep of ISRAEL.
The new Covenant is for the HOUSE of ISRAEL.
JEREMIAH 31: 33*"This is the covenant I will make with the house of Israel after that time,"
Paul says: No, a man is a Jew if he is one inwardly; and circumcision is circumcision of the heart,*by the Spirit,*not by the written code.", & "In him you were also circumcised,*in the putting off of the sinful nature,*not with a circumcision done by the hands of men but with the circumcision done by Christ."
The prodigal son in a foreign country, was not merely a parable of a son going anywhere on Earth. It describes those God foreknew, returning to him, meaning they were there at one point in time, for those God foreknew, he also predestined.
Jesus said he was sent from above to find that which was lost to take us home again. Meaning "for they are not of the world any more than I am of the world."
Think of it like this, to make it home, one must know where one came from, period. And if our home is above, what must that mean?
Like this: you have Oklahoma above Texas. Say a man was leaving home, he left Oklahoma and he went to a completely different state, he went south to Texas. But while he was in a foreign state, the laws of that place and the actions of others steered him away, and led him into a terrible accident, he forgot where he came from a long the way. But say this man's brother came to Texas to find his lost brother. He told everyone he was from above and the laws of this place didn't apply to him. But they hated him, they could not understand what he was saying because his laws and speech were foreign to them. But he found his brother, and his brother remembered suddenly where he was from, he remembered his daddy's rules and the laws of his state. Well soon all this guy's buddies who led him into all this trouble started to dislike him too. The Lost man started talking like the guy from above in Oklahoma. But the man that found the lost brother, well he went back home, his work was complete and told the lost brother he had to stay, cause there may be others that these crazy guys from below had led away, and he told the brother not to be afraid of all the wild people, while he was here the laws of the foreign country wouldn't apply to him because he would be an ambassador now, and every ambassador is governed by the laws of his own country while in this foreign place, so do not be afraid, he would have diplomatic immunity.
If the man from above had to come below to find that brother that had wondered away, doesn't that mean they are both from the same place? You think both brothers foreknew each other before coming to the wild foreign place?
You see the one wild child was lost, he had forgot the laws of his home or even how to get back to that place.
To be the Lost sheep of Israel, of the heavenly one, well that's just deep. Not all scripture is about earthly things, Isaiah 54 is about the heavenly Jerusalem, but they still call it Zion. The new covenant is for us, but God says its for the house of Israel, but we fail to look at that and remember there's two houses of Israel, one above, one below, they are both called the same thing, and this is why it's important to understand, our citizenship is in heaven.
And that is the house of Israel, and those members have been circumcised in heart, washed clean, all done by the hands of Christ. Such a thing makes a person a member or the heavenly Jerusalem as Paul says: Such a man's praise comes not from men but God.
