There is no gray.
There is only black and white. What we perceive as gray is really just a conglomerate of blacks and whites, indiscernible within our ability to perceive.
All things break down to this: is and is not. 1 and 0. On and off. A pen (what we call a pen) is a conglomerate of infinite on/offs created by God, tinkered with by man. This is true for all things down to the smallest thing knowable by man (whatever that happens to be).
What is and is not comes from that which wills it.
