Paul did say (yet again) that not all who are descended from Israel belong to Israel, and he even used Jacob and Esau - twin brothers of Israel himself, to demonstrate this and God's purpose of election. So, irrefutably, not all of Paul's fellow countrymen are among God's people; not all his people are God's people; not all of them are true Jews in the sense of what he said in Romans 2:28-29. So yes, in Romans 9-11, especially Romans 9, he is contrasting who outwardly is of Israel to who the Israel of God really is. Ethnic/physical Israel and God's eternal/spiritual Israel, consisting of His elect, are two different groups of folks... not that they are mutually exclusive, as God's eternal Israel will contain a number of those who were part of earthly, physical Israel. This Venn diagram should suffice:
The inner circle is not to scale; we cannot know the true percentage of the people within the outer circle who are or will ultimately be also in the inner circle.
Grace and peace to all!
God made a covenant with National Israel.
this covenant had nothing to do with anyone's salvation
it had nothing to do with them obeying him
It had nothing to do with whether they believed in God or not
He gave it to Abraham, As their natural father, that gift still belongs to them (lev 26 gives the guidelines on what would happen if they sin)
what you call spiritual Israel. is actually the descendants of Abraham concerning another aspect of his covenant, "in you (literally in your seed) shall all the nations be blessed.
The seed of course, and I think we agree, is Christ
I am part of one of those nations (the united states) that God said would be blessed because of Abraham's seed..
I am not part of the promise given to Abraham concerning the national covenant, It was never given to me or for me. It was given to Abraham and his people as a GRACE gift..
Just like salvation was given to me as a grace gift.
Both are eternal
Both are based on God and his character, and not based on us or our character.
Once concerned eternal life. The other concerned a peace of property.
Both have consequences if we sin (them as sown in Lev 26, me and us, we will be disciplined, we will suufer loss. We will suffer hardship. we will suffer the results of our sin. We may even suffer the sin unti death if we are beyond help, But in neither case will God give up on the promise he made. If he does, he deny's himself. because he made the promise its on him!
