fire fly nights

now when i am out in the evening i am in the midst of the crazy flight of fireflies. even though they are small and the light is very tiny, their sparkly selves are hard to miss. little missionaries of cheer in the rushing darkness. i once read a book about the greek experience that put forth the idea that the great ideas of greece, democracy and all that, was the result of the absolute clearness of the air. i have not been to greece so cannot attest to the air, but i have not every seen a cloudy picture of greece. i guess you wouldn't do that...take pictures of cloudy weather, if you wanted tourists to come. in england, well, not that many really clear bright sunny days. so how important is light, and where the light is? you cannot see the fireflies in the daylight, i am not sure if they actually fly around in the day time. Christians are to be lights. surely the brightness of the light partially depends on where you are. does it shine any less in goodness than it does in darkness. it is easier to notice in the night, but does it shine less in the day?
