Let. There. Be. Light.
Let (God). There (Differentiation). Be (Surface). Light (Matter).
Let (Nothing). There (Nothing). Be (Nothing). Light (Something).
Light chose, at will, to become something rather than simply remain as one (good) part of the differentiating nothing, as even God, his Differentiation, and the Surface that these two parts now occupy, can only be defined as indefinable no-things.
Therefore, one could argue that Lucifer– the Light Bearer– was the topological outburst of Light, the one part of the nothing that chose to unnaturally become something else, and/ or further yet, being plausibly identified as the origin-source of Evil itself. As Evil, at its most repugnant base, is the dreadful act of going against the natural divergence of the ever-becoming good.
