According to the Torah, the concept of God is that of a singular, absolute reality. The term Elohim (אֱלֹהִים) denotes a Supreme Force, grammatically plural and uncountable yet singular in essence, like the word "water — מַיִם." This force is defined as YHVH Elohim (יְהוָה אֱלֹהִים), the Sovereign Power over all celestial and terrestrial realms. The core principle is that no form was perceived at the revelation at Horeb, forbidding any image or representation of creation, including celestial bodies, to prevent idolatry. These are merely allocations to the nations, not objects of worship.
The central tenet is the absolute oneness of God, declaring that YHVH is God in heaven and on earth, and there is nothing else. This means only God truly exists; all else has contingent existence within His reality. To perceive the world is to perceive God's creation, always being in His presence without perceiving a form. True awareness is the constant realization of God's necessary existence and our dependence on it.
This stands in direct opposition to the idea presented by the serpent in Genesis, which promised that eating from the tree would make humans like gods, knowing good and evil [an idea of illusion]. That temptation is the root of believing in multiple powers or authorities outside of or independent from the one God. It is the error of attributing autonomous power to any aspect of creation, which is the essence of idolatry. Therefore, one can always "see" God in the sense of perceiving divine providence and unity in all things, but this vision is strictly non-corporeal and non-representational.
The Torah describes God with human-like emotions like love or anger to make His interactions understandable, but these are not literal. God is incorporeal and omnipresent. Human existence is affirmed, as humanity is created in the divine image. To nullify one's purpose is to nullify this divine expression, making human life intrinsically valuable to God's plan.
