I don't take that view either. My view is more basic. I think these sorts of questions can be divisive. I say, why start a fight over some theological question which has no application to my life? I don't honestly know who is going to heaven and who is not. Only God knows that, it is God's choice, after all. So, the bible does call the Jews the chosen people of God, and I feel like they are. This way we can all be friends.
Jesus did not die on the cross to teach us theology. He died that we might find salvation, and the presence of the Holy Spirit.
I try to avoid holding too tightly to complex theoretical conclusions which have little or no practical value. How is thinking that Jews are saved or not going to affect me? I mean, theology is nice, and can be edifying. But, having a perfect theology is not really the point of being a Christian.
When it comes to salvation, we all have a responsibility to figure out our place in the world, and our relationship to God. If I find a Jewish friend who is questioning his faith, I am happy to share mine with him. But, if my Jewish friend feels like he has all the answers he needs, I don't push my faith on him. It is his choice what he believes, and if he tells me he is finding plenty of fulfillment and salvation in his life, who am I to tell him he is wrong? He knows his own soul better that I do.
