We know that light exists in absence of darkness. But this would assume darkness came before it as an inevitable state of existence. Perhaps it’s best to say that light exists in spite of darkness. Darkness is pervasive, expansive, suffocating, final. Yet there is hope through faith, which is self same as light.
The important function of light is held in two governing principles. First, light must come from a source which emanates power. The details of the source—such as how the source is the source, under which authority, and from where the source is sourced—are not so important in this analysis. Let’s just focus on the fact the power source from which light emanates exists. This relates to light’s second governing principle: it has an undeniable essence. This means that while a light may shine in Beijing, another in Toronto, and another in Accra, the separateness of their manifestation is held in tandem by their common essence. In other words, the very characteristic(s) of the light and its potential are the same although all three lights may have different vessels.
If we can agree that light has a source and an essence, can we also posit that the source and essence must have a creator? Are they the same creator? Or are there two? And, further, who created the creator? As I’ve alluded to, perhaps the (unanswered) questions point to an inevitable existence of something much grander than our logic can reason. This, even though difficult to grasp, ought not detract from the fact of the unanswered questions and their merit.
There is no real purpose for a vessel to carry light in darkness. Might I suggest a simple enough way to understand the phenomenon is as a gift intended to light one’s path. Only the creator could distribute gifts of choice at her will; though the rationale may escape (some of) us, she is presumably omniscient. So, then, we can perhaps take a leap of faith and reason the perfect use of the creator’s gift is eternal light through the source for some intended benefit (Romans 6:23).
Now, what happens when a light dims? I would say either the wick within is not properly lit, or the light is not connected to the power source properly. In each case, the consequence is a vessel lacking brilliance. On the flip side, how does a light grow brighter? This is nearly impossible, if not for two specific scenarios. Either the essence of the light changes/is enhanced—which would require all lights to grow brighter. Thus, this rationale fails its own test. The second hypothesis is by means of a power surge or voltage spike directly from the source. Now, this means that in order to benefit from a possible spike, the light’s vessel must be connected to the power source at all times. Otherwise it might miss the surge it needs to keep burning.
