What is the core teaching of Jewish Religion (Judaism)?
Belief in one G-d, who is all-knowing, undefined and the Creator of all things. Belief that G-d has a purpose for humankind and that purpose is achieved on Earth. Belief that G-d communicated His purpose to His people 3300 years ago at Mt. Sinai and that He continues to send us messages and hear us talk to Him. Belief that His purpose requires every human to acknowledge Him and live a moral life- and that the Jewish People live according to a complex religious code. Belief that the world will eventually reach its goal and we will all live in peace and spiritual enlightment at that time.
