Answer 2

The Jewish tradition identifes 613 commandments in the Torah that are binding on all Jews. These cover a wide range of things from, for example, not committing murder at one extreme to avoiding wearing clothing made of a mixture of linen and wool at another. Many of these commandments have a strong ethical basis, as in love your neighbor as yourself, while others have no obvious reason, such as not planting two different crops in the same field. Some of the commandments have become impossible to obey since the Temple in Jerusalem was destroyed by Imperial Rome in the year 70. Sacrifices, for example. The Jewish tradition holds that if it is impossible to do, God will forgive your not doing it.

Another writer mentioned the idea of Jews being a chosen people being a reason for all these commandments. Chosenness does not imply a shortcut to salvation. The Jewish tradition holds that "the righteous of all nations have a place in the world to come" (as it was put by a medieval Talmud commentator). If anything, the complexity of Judaism makes it a harder road to follow than that of being a righteous gentile.
