The material world is not inferior, matter in itself is not lower or worse, and in a sense the physical world may even be considered the height of Creation.
It is the marvel of Creation for the paradoxical reason that the very existence of matter is a condition that seems to obscure the Divine, and thus could only be the result of a special intention on the part of the Infinite.
Matter is a sort of standing wave between the manifestation of God and the hiddenness of God; it is defined by its limitations.
To retain its separate and independent existence, infinite force has to be exerted on every particle.
