The sun rises and the sun sets, and hurries back to where it rises. The wind blows to the south and turns to the north; round and round it goes, ever returning on its course. All streams flow into the sea, yet the sea is never full. To the place the streams come from, there they return again.
The earth is a self sustaining system--methodically replenishing itself--daylight, darkness, wind, and water.
How awesome is creation. It's no wonder that man selects to worship it--ever focusing on the creation he sees, hears, and feels--and neglecting the incomprehensible Hand behind it.
