The way i see it Jews and Christians worship the same God.....the problem is that the Jewish faith does not "know" him due to their denial of the savoir that God promised them....
God was/is not wrong in choosing the Jewish people as his "choosen people".....the Jews were wrong and missed the boat when they failed to recognize the "promised savior". God still watches over his choosen people and rejoices whenever one comes to "know" him.....God knew before hand that his choosen people would reject him as a whole.....
We do, we just differ on our understanding of His nature.

Your believing this does not make it true.
