Have you ever heard of phototaxis? Phototaxis is the automatic movement of an organism toward or away from light. If an organism is positively phototactic, it will move toward light. A perfect example of this type of organism is the moth. Moths fly toward light. That is why you will see them at night flying around your porch light. Organisms that are negatively phototactic, on the other hand, move away from the light. Cockroaches are negatively phototactic. That’s why they scurry off to dark corners when you turn on the kitchen light and interrupt their midnight snack.
When it comes to people, you can say that there are some who are positively phototactic and some who are negatively phototactic. But this phototaxis is not a movement toward or away from physical light. Rather, it is a movement toward or away from a spiritual light. That light is Jesus Christ, who is the Light of the World (John 8:12). Jesus is the light that shines in the darkness, exposing the evil deeds of men. Those who do evil, who live a life of sin, are not only living in the darkness, but they also embrace it (John 3:19). They hate the light and move away from it to avoid having their evil works exposed (John 3:20).
On the other hand, there are those who do what is true, who live by the truth of God’s Word. They live righteously, seeking to obey God’s commands and become more like Christ. These people move toward the light. They are not afraid of having their works exposed by the light (John 3:21). They seek to follow the Light, to follow Christ. And, in doing so, they reflect His light to those around them. They themselves become the light of the world, allowing their good works to be seen by others and give glory to God (Matthew 5:14-16).
We all have a choice. We can be negatively phototactic, choosing to remain in the darkness of sin and avoid the light. Or, we can be positively phototactic, turning from our sin and choosing to come to the Light, to follow the Light of the World, Jesus Christ.
