Unlike other ancient Near Eastern gods, the Hebrew God is portrayed as unitary and solitary; consequently, the Hebrew God’s principal relationships are not with other gods, but with the world, and more specifically, with the people he created. Judaism thus begins with ethical monotheism: the belief that God is one and is concerned with the actions of humankind. According to the Tanakh (Hebrew Bible), God promised Abraham to make of his offspring a great nation. Many generations later, he commanded the nation of Israel to love and worship only one God; that is, the Jewish nation is to reciprocate God’s concern for the world. He also commanded the Jewish people to love one another; that is, Jews are to imitate God’s love for people. These commandments are but two of a large corpus of commandments and laws that constitute this covenant, which is the substance of Judaism.
Thus, although there is an esoteric tradition in Judaism (Kabbalah), Rabbinic scholar Max Kadushin has characterized normative Judaism as “normal mysticism”, because it involves everyday personal experiences of God through ways or modes that are common to all Jews. This is played out through the observance of the Halakha and given verbal expression in the Birkat Ha-Mizvot, the short blessings that are spoken every time a positive commandment is to be fulfilled.
