Answer: Faith is defined as the quality of bestowal in Kabbalah. This is not what is accepted in religions. All Kabbalistic terms originated several thousand years prior to the appearance of religions.
Jewish religion came into being 2,000 years ago. Before that, the Jews only had Kabbalah and people existed sensing two worlds simultaneously: our world and the upper world. Later on, they fell from sensing the upper world and remained sensing only our world, and what resulted became known as Judaism, religion.
The Jewish nation lost the condition of “Love your neighbor as yourself” and began to engage in the routine performance of the commandments – Mitzvot. From that, Christianity appeared with all of its branches and later on, Islam. Judaism, Christianity, and Islam do not belong to Kabbalah.
Kabbalah explores the upper world and brings a person to its revelation while living in this world. That is why in Kabbalah, there is no need to believe in anything. In Kabbalah, faith is called the quality of bestowal, the quality of influencing others.
