Two facets of creation are recognized here: its goodness, and (in the adjacent dilogic) its temporal reality.
The Bible itself describes the creation in common words; it places God's blessing of reality and recognition on the stars, air, water, plants and animals of our world. These same common words were used even in describing creation before the Fall. This one creation is real to God, as well as to us. It is not to be despised, but rather was declared by the Creator to be "very good".
Therefore the physical world is not inherently earthy, unspiritual, or
evil. Moreover, its Creator is not caught up in a struggle with its
matter. These Platonic ideas are not biblical.
