All over Jerusalem and Israel you will see members of Chabad helping Jewish men to put on Tefillin. Gutman Locks has another goal as well and that is to teach Jewish young people that they must avoid intermarriage. He also makes and interesting point, that if a woman converts only for the purpose of marriage, it may Not be a Kosher Conversion!
He also tells them that all religions in the world are based on belief--that is, whatever you believe that is your religion--kind of like the flavor of the day. A Buddhist can become a Muslim or both can become Christian. Only Judaism is different because Jewishness comes from the Mother. We are a People--Not a Faith!
