Religion - Judaism
Judaism is a religion that is actually very closely related to one of the world's largest religions - Christianity. However, Judaism represents a very small group of people, mostly Jews living in Israel and across the world. The two religions have identical roots, and they even use almost identical sacred texts.
The first five sections of the Jewish holy text is exactly the same as the first five sections of the Christian Bible. This is known as the Pentateuch, consisting of the books of Genesis, Exodus, Leviticus, Numbers, and Deuteronomy. Believers of Judaism value these five books so much that they make them required reading for their children. By the time Jewish children reach the age of 12, they are expected to know the Pentateuch by heart.
Judaism is unique in its own ways, though. For one, they are very particular with following nearly all the laws written in the books of Leviticus and Deuteronomy. That is another sign of how much they value what's inside the Pentateuch. There are over 600 individual rules in those books, and followers of Judaism strive to adhere to every single one of them.
Judaism believes that the way to please God is to faithfully follow all of the more than 600 laws enumerated in Deuteronomy and Leviticus, with no exceptions. Missing out on even one small rule will displease God and cause him to be angry. For this very reason, Jews are very, very particular with their laws.
Despite having similar holy texts, adherents of Judaism do not believe that Jesus Christ is the savior of mankind. They say that the only way to God is by following their laws. To them, favor from God must be earned through good deeds and good character. For this reason, their culture and all aspects of their lifestyle are designed around the Leviticus and Deuteronomy laws so that it is easier to follow them.
