Many of the major religions of the world have a lot in common. The similarities between Christians, Jews and Muslims, for instance, can be seen in the story of Abraham and Sarah.
The history of the Jewish people begins in the Middle East during the Bronze Age. God spoke to a nomadic leader called Abram (later called Abraham) and promised him that he would be the father of a great people. Abraham simply had to do exactly what he was told with unyielding faith.
