I wouldn’t recommend holding your breath while waiting for Israel to convert to Christianity.
... LOL ... true that ... or any other nation in the world ... :-) ...
It’s not a practical solution for winning wars. Of course Jesus never said one’s personal salvation was for winning wars!
Israel isn’t going to convert to Christianity; the remnant of Israel is going to recognize Jesus as their Messiah when He returns. The same God who says this also says through His prophets and in the New Testament through His Son and the apostles that ISRAEL WILL NOT BE DESTROYED.
There are going to be more than a few battles, but God, the God of Abraham, Isaac, and Jacob, the God of the Christians, will deal with the nations who have come up against Israel.
Where does that put us? Our illustrious leader has pitted us against Israel.
