But the reason I mention this is because the last scene in Episode 9 features two of the astronauts looking at the beta object. As it turns out, all the astronauts, save one, can see it, has had visions, and can hear the music that seems to serve as it's method of communicating. The one astronaut who can't see it can only see the light that is coming from it.
This made me think. When we "see" the light, which is Christ, we also see God by eyes of faith. The unbeliever sees the light, but can't see God at all. In fact, the unbeliever wont even entertain attributing God as the source of the light, literally because they CAN'T see it. They'll find anything as an explanation of why the light is there, even suggest that the light is us. But since they can't see the object of faith, they will always attribute the light to something other than that which it comes from, thus shunning the light itself. After all, what good is light if you can't actually nail down it's source?
This should give pause to any unbeliever. The light of Christ is upon you, but because you can't see the source of the light with natural eyes, you reject the light. Those who can see the light and know it's source have had the source revealed to them by the source itself. You who cannot see the source, conversely, cannot know the source because the source has not revealed itself to you. All you can see is the light, and you attribute that light to everything but the source of the light itself.
