God began by making covenants with His creations to restore us from the Fall. First, with Noah (individual), then with Abraham (family or tribe), and then with an entire people, the Jewish people (with Moses as their God-selected leader). When Christ came, He fulfilled the Jewish law and made His Church available to people of every nation. God could have selected other peoples to do this with, but since He selected this way, we can be sure it is the most perfect way. At any rate, the Jews are God’s chosen people and we should pray very much for those who do not recognize the Messiah is come because those to whom more is given, more is expected. It is really cool, though, IMHO to have a group of people who had a covenant with God still in existence carrying out Mosaic traditions today.
