The position that seems most logical to me is that G-d promised Abraham that he would look after his people. Jesus may be the path for Gentiles but the original Covenant with the Jews still stands. To suggest otherwise is to suggest that G-d breaks his promises does it not?
There is no different path: Jesus is the only path. At the end of the world, in His second coming, he will finally be recognized as the Messiah by all peoples including his own.
He will fulfill all the Biblical promises to the Jewish people and welcome all the righteous Gentiles into his kingdom as well.
Where did I suggest otherwise? I said they would not become Christians at their death. I believe I am correct. God never breaks a promise!
