A Computer (Part 3) - Water

"Take a long, hard look. See how great he is--infinite, greater than anything you could ever imagine or figure out! "He pulls water up out of the sea, distills it, and fills up his rain-cloud cisterns. Then the skies open up and pour out soaking showers on everyone. Does anyone have the slightest idea how this happens? How he arranges the clouds, how he speaks in thunder? Just look at that lightning, his sky-filling light show illumining the dark depths of the sea! These are the symbols of his sovereignty, his generosity, his loving care.  (Job 36:26-31 MSG)


There's quite a bit of talk about water right now.  Considerable rainfall has resulted in dangerous flooding conditions in more than one area in the United States.  We are affected by such tragedies because they are unusual, disruptive, and even devastating to our usual pattern of life.  Why?  What is "normal" when it comes to rainfall?  Where does the water normally go?  For that matter, where does it come from?


Well, we learned that in science class.  Remember?  Water on the ground evaporates, becoming "lighter" than air and the molecules ascend into the sky.  Once they get "up there", a combination of gravity, temperature changes, and the atmosphere all cause the water to stop going up, gathering into clouds.  These clouds gather more and more water until gravity and other forces finally cause the clouds to "let go" of their payload, dropping the water back to earth in the form of rain, hail, sleet, or snow.  This whole process is one that we call, "The Water Cycle."


Now scientists tell us that we need water to survive.  Our survival time is directly connected to factors such as temperature and the presence of shade.  The bottom line is this, though.  Without water, we would not survive.  The sun, heat, evaporation, the atmosphere, gravitational pull, air movement...each of these things must be in place for the water cycle to work, for water to remain on the earth, for us to have cleaned water to drink.  Without the water cycle, life as we know it would cease to exist.


It's almost like multiple pieces of a computer that must be in place in order for the computer to function.  Click...Click...Click...I'm glad each piece is in place.
