Why do Xians and Jews seem to talk past each other?

I have seen a number of conversations (mostly on the web) where Xians and Jews are discussing religious things. My impression is that they frequently talk past each other, like two skew lines neither intersecting or running in parallel. After pondering this, I submit that the reason is that the core question in each religion is different:

The Xian question: How can I be saved?

If you are not up on Xian-speak, this could also be rendered – How can I be made right with God? It could also less accurately be asked as – How can I get to heaven? Or How can I have a place in the World to Come?

I have seen on a Roman Catholic site - "How can I receive God's grace?" and I submit that the nuances between "How can I be saved?" and "How can I receive God's grace" illustrate some of hte differences between Evangelicals and Catholics.

The Jewish question: How should I live?

I think that part of this comes from the fact that in Xianity people are born outside of a covenant with God and must enter. In Judaism, Jews are already in a covenant and have been for a long time. It is not that Jews never ask about being right with God or the World to Come, and it is not that Xians never ask how they should live. It just seems that the default question of each is not the same. Xians spend much time, energy, and focus on witnessing, converting, being born again, etc. Jews (well religious Jews) seem to spend a great deal of time on figuring out exactly how they should observe Torah.

I know far less about Islam than either Xianity or Judaism, so I am still trying to figure out their question. My best shot right now is:

The Muslim question: Will you submit?

And just for fun, if I had to pick a question for Jesus, it would be: Who do you say that I am?

Jesus had this fascinating characteristic to be both humble and meek while at the same time He acts as though it is all about Him. And He does it so matter of factly. He does not seem boastful or arrogant, yet He still seems to regard Himself as the center of all things.
