The following resource is from desiring God.org. Okay, let's read verses six through eight.

Here's the reason the word of God has not fallen.

For not all who are descended from Israel

belong to Israel.

And not all are children of Abraham because they are off his offspring. But through Isaac, shall your offspring be named, not Ishmael, the Isaac.

This means, for now he's interpreting what he said,

this means that it's not the children of the flesh who are the children of

God, but the children of God, but the promise are counted as offspring. That's his argument.

Now he's going to give some foundation for it in verses 9 through 13

from the Old Testament, but let's see if we can figure out his argument here first.

Why hasn't the word of God to Israel, the promises, the covenants, why haven't they failed?

And his answer at the end of verse six is,

it would be a mistake to say the word has failed because those who have descended from Israel are

is perishing because not all those who have descended are Israel.

That's his argument. Not all Israel is Israel.

Which means the promise has never been that all ethnic Israel will be saved, that there can't be lost ones.

There's never been, may put it like this, there's never been a necessary connection

between being born Jewish and being a child of the physically belong to Israel.

So he's clearly distinguishing two kinds of the use of word Israel, right?

This use right here and this use right here are different.

If you are born of Israel... this one you say you say you say of

well of course I belong to Israel
