For Chabad Chassidim, it is not enough to be a G–d-fearing Jew. This fear of G–d must come through Avodah, effort. Concerning this, the Rebbe relates:
A Chossid once asked the Tzemach Tzedek to bless his son with a good memory. “He should remember everything he sees and hears when among the Rebbe and Chassidim, and automatically he will be a G–d-fearing Jew. The Tzemach Tzedek responded, “It has been already over 50 years that my grandfather (the Alter Rebbe), my father-in-law (the Mitteler Rebbe) and I have been toiling that Chassidim should be G-d-fearing through Avodah, and not automatically.”
