A Little About Optics

According to Wikipedia, “Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated”. In simple English, reflection happens when a wave hits a medium and bounces back at an angle. In the case of light, a ray hits a mirror and returns to the air from which it came. On the other hand, “Refraction is the change in direction of wave propagation due to a change in its transmission medium “. An object which allows refraction is said to be translucent, it allows light pass through it.

The Sun and The Moon

We have been taught that the moon reflects the light of the Sun. The Sun is the true source of light and the moon only appears to have light emanating from it. The moon appears to be a source of light. Some people attempt to describe our relationship with God as one between the Sun and the Moon, we being reflectors of the light emanating from God but I think there can be a more accurate description: Light passing through us.

Light Passing Through Us

Light passing through us implies that we are the first recipients of the effect of the Light before we have it directed at others. It implies that we are conditioned in a certain way, as translucent objects with respect to God’s light. It implies that we absorb some of that light before it ends up hitting another object. I think I would be more comfortable thinking about God’s light passing through me that simply bouncing off me. 

20 “according to my earnest expectation and hope that in nothing I shall be ashamed, but with all boldness, as always, so now also Christ will be magnified in my body, whether by life or by death. 21 For to me, to live is Christ, and to die is gain.” (Philippians 1:20-21)
