Well, it seems that Judaism is more of a fashion-trend or the commercialization of God, rather than cordial and invitational to teach others what God is about. I always hear of Muslims and Christians talking of God's love and mercy, but I rarely--if ever--hear of a Jewish person talking about how God loves you, created you, and wants to be in a deep and personal relationship with you.
And to say that they are so rich would be a comical understatement. Persians, Chinese and Indians are definitely richer, because they numerically outweigh them
but on the issue of God, i have yet to hear of an emotive, sentimental invite to be emotional with God. I don't know, it just feels as if they haven't done a good job in teaching their faith as the other two have.
