The symbol of the work week, which is crowned by a day of rest (Gen 1:1-2:3), is an expression of how good, beautiful, and wisely ordered creation is.
From the symbolism of “the work of six days” we can derive important principles: (1) Nothing exists that was not called into being by the Creator. (2) Everything that exists is good in its own way. (3) Something that has become bad still has a good core. (4) created beings and things are interrelated and interdependent. (5) Creation in its order and harmony reflects the surpassing goodness and beauty of God. (6) In creation there is an order of complexity: man is superior to an animal, an animal is superior to a plant, a plant is superior to inanimate matter. (7) Creation is heading for the great celebration when Christ will bring the world home and God will be everything to everyone.
