Judaism was the among the first to promote a belief in a monotheistic god. They got their laws from that God through their prophets. They wrote down their history and their laws and refined them.
The adherents to Judaism are among the most ardent believers. They follow the tenets of their religion faithfully. God has rewarded them with superior genetic traits. (Or was it that because they were genetically superior that they found God?)
Despite their small numbers, they are leaders in fields such as medicine, law, politics, education, science, literature and the arts. God has been good to them, and they have great material wealth.
Of course, one might argue that they wander off track somewhat and get punished, for they believe in a vengeful God, and it seems he does not disappoint.
Jesus was Jewish and possibly the Messiah predicted. On one hand, the followers of Judaism contribute greatly to society, but they do not follow the message of Brotherly Love as taught by Jesus (which was the basis for the Islamic religion).
Do you think the religious Jews (the majority of the culture) are mad irrational people?
