There are 3 reasons: First, Jewish tradition does not say you have to be a Jew to be saved or to go to heaven. The traditional Jewish view on this was stated by a Medieval rabbi as "there is a place in the world to come for the righteous of all nations." As a result, there is no moral obligation to convert people, only to help them be good. Second, being a Jew is hard. Jewish tradition holds that all of humanity is bound by the Noachide covenant, the one God made with Noah after the flood. The terms of this covenant are inferred from the list of reasons given in Genesis for the flood. Jewish tradition holds that there are only 7 "Noachide commandments." In contrast, Jewish tradition counts 613 commandments in the Torah that apply to Jews. Judaism considers any religion that teaches the 7 Noachide commandments to be a legitimate path to righteousness. Third, being a Jew is dangerous. Today, there are still antisemites who want to kill Jews. Today, conversion to Judaism is still a capital offense in Saudi Arabia, and it was a capital offence just about everywhere in the entire Muslim and Christian world not that long ago. So, Jews have an obligation to warn potential converts that they are taking a risk.
Unlike other religions, Judaism is not centralised and there is no one leader.
Generally it is Christians and Buddhists who seek out converts, and none of the other main religions (Judaism, Hinduism, Islam.)
The biggest difference between Judaism and other religions is that Judaism has few if any converts. If you are not born into the religion, then you are not part of that religion. Buddhism, Christianity, Islam, Sikhism, Jainism all welcome converts.
Judaism does not have a "representative on Earth". Unlike some other religions, there is no Jewish intercessor with God or a living demi-god.
Back when Judaism was first Founded, all other religions were polytheistic. Judaism was monotheistic.
Christianity.
Judaism was the only belief that abhorred idolatry.
Zoroastrianism, Judaism, Christianity, Islam, and Sikhism are the better known monotheistic religions.
No. It is the text of Islam (Muslims). Other texts such as the Bible and Torah are used in other religions such as Christianity and Judaism.
Christianity and Islam are the two major ones, but there have been several other offshoots of Judaism.
The Middle East is the birthplace of all three Abrahamic Religions, Judaism, Christianity, and Islam. Along with other religions such as Bahá'í, Druze, Yazidi, and Zoroastrianism.
Judaism and Christianity are two religions connected to each other as Christianity stems, or has its roots in, Judaism; they are, however, separate religions. Catholicism is the largest denomination in the Religion call Christianity.
