Light Pollution

You can't see the stars as well in the city as you can out in nature. This is because of an effect called "light pollution." I'm not sure exactly how it works, but somehow, the lights from the city make it harder to see the stars.

I think that many people have the same problem, spiritually. They've gained so much of the knowledge and the wisdom of the world that it makes it harder for them to see the knowledge and wisdom of God. They don't turn to Him for guidance because they think they get enough guidance from the world, never mind that it's leading them in the wrong direction.

Of course, not every intelligent person has this problem. There are also many people who know a lot, but still trust that God knows more. We should be like that. As we gain knowledge and wisdom here on Earth, we should be careful to not let it blot out the knowledge and wisdom we have gained and can yet gain from God. Learning is good, but we should never make the mistake of thinking that we've learned enough that we don't still need God to teach us. Earthly light is fine, so long as it doesn't make it harder for us to see and follow heavenly light.
