"The Light shines in the darkness, and the darkness did not comprehend it."
Darkness and light are not equal opposites like we sometimes suppose them to be. Darkness is simply the absence of light. Do you feel like you are in darkness? It is because there is an absence of light. Wherever there is darkness, there is no light, but as soon as you turn on a light, the darkness is gone. Light is the absolute death of darkness, but not vice versa. Darkness is a servant of the light. Darkness can never overcome light, but light pierces darkness immediately, and the darkness has no answer. Satan, for all his cunning, cannot comprehend the Light. Darkness and Light cannot coexist. They are mutually exclusive. There is no such thing as a "light darkness" or a "dark light." Where there is darkness there is no light, but simply turn to Jesus and allow Him to be a Light to your dark places and you find those dark places are no longer there. It is reassuring to realize that, no matter how deep your own darkness seems, it is not an entity in itself, but exists only as the absence of light. Not only that, but it is reassuring to realize how quickly light fills a dark room, when a lightswitch is flipped. Often, in our darkest moments, Jesus seems very far away, but it only takes a instant for his light to permeate our circumstances.
It is also interesting to consider that another form of darkness is shadow. Shadows are the lack of light resulting from light being blocked by an object. Sometimes, we are in the dark because we let other things get in the way of our source of light. We stand in the shadows of our own idols. We would be humble were it not for our pride. We would be generous were it not for our greed. We would be loving were it not for our selfishness. When darkness settles around us, the first thing to check is, "Is the light on?" The second check is, "Am I hiding behind something?" We have to surrender all our idols and gods to see the light clearly.
FEAR NO DARKNESS!
