Jews do believe in a Hell (Sheol) and the Devil (ha-Satan).
Jews practice the Shabbot on the actual day, Friday at dusk to Saturday at dawn, whereas the Christians changed it to Sunday from midnight to midnight.
Jews do not believe that Jesus was a prophet nor a messenger of God, but a false prophet; it is only Muslims and Christians that honor Jesus as the Messiah, but Muslims don't regard Jesus as God, nor the son of God.
Jews don't have the concept of original sin since Adam and Eve repented and were forgiven, mankind are born without sin but turn to sin afterward, but have the chance to repent for their sins. Christianity believes that everybody is born of sin and have to believe in the blood atonement of Jesus.
Jesus (a Jew) stated that he was sent only to the lost sheep of Israel, not the Gentiles, that Jews must still abide by the Ten Commandments [see Matt 15:21-24]; whereas, the Christians stated that Jesus was sent for mankind, and that the Law doesn't have to be followed, no longer valid. [see Ephesians 2:8-9; Romans 3:20, 3:27-28]
Judaism has some cultural influence from ancient Greek and Babylon; whereas, Christianity is a retrospect of Roman and Germanic paganism.
