Mainly Judaism, followed by Islam and Christianity. In addition, there are small sects such as Baha 'i and Samaritan. Judaism is undoubtedly the most important thing for Israel. Because according to the Hebrew Bible, Israel was founded. At the beginning, the foundation of Jewish restoration was because the Bible recorded that God promised the Jews this land, which was a "promised land". Both Christianity and Islam can broadcast freely in Israel, but the target is often non-Jews. Because there are Christian holy places in Israel, many Christians come to pilgrimage every year, which brings considerable tourism income. Baha 'is can't develop followers in Israel, but Haifa has the main altar of Baha 'is. Samaritan basically does not accept converts. Relatively speaking, the influence of religion on development is subtle. For example, Judaism, on the surface, many ultra-orthodox Christians-caliphs do not work, concentrate on studying the Torah, and refuse to perform military service. They are saved by government subsidies and charity, and they are a group of people who are of no help to social production. But the existence of these people objectively guarantees the continuation of Judaism. This is also important for Israel. The value of Judaism to Israel cannot be measured by money. In fact, it has preserved the cohesion and moral ethics of the Jewish nation and exerted an important influence on the cultural development of Israel and even the whole world. Jews only have140,000, but only 7 million people can speak Hebrew. Jewish books handed down from generation to generation need a lot of manpower to preserve. Israel has spared no effort to protect its religious traditions and spent a lot of manpower and financial resources. Without Judaism, some documents about the Bible would be lost. This will cause immeasurable losses.
