I'm a little confused here.
Are you saying that the Jews who rejected Jesus were the tribe of Judah, and that the Gentiles to whom the gospel has spread and are accepting Jesus as savior are of the House of Israel?
And this is how God is remarrying Israel?
Great question and I’m confused, too.
Yes, though there are two factors - There still also needs to be a physical/nationalistic representation of the tribes too. In the ending battles they have armies, and are included by name - so there must be a physical manifestation, and it must needfully be a distinct thing from what we know as the nation of Israel right now...
The Jews ARE the House of Judah. The very name 'Jew' is a shortened form thereof. You will not find 'Jew' used in the Bible to describe any other. 'Jews,' the House of Judah, have within them the tribe of Levi (the Kohenim, priestly line), part of the tribe of Benjamin, and of course the tribe of Judah. All the other tribes, including the rest of Benjamin, are figured in the House of Israel. The NATION of Israel, the current, physical Israel IS the House of Judah.
