When God created, he invented the media as he went, calling into being what had existed only in his imagination, and along with every free choice came a limitation. He chose a world of time and space, a “medium” with peculiar restrictions: first A happens, then B happens, and then C. God, who sees future, past, and present all at once, selected sequential time as an artist selects a canvas and palette, and his choice imposed limits we have lived with ever since.
