Job 5:9-10 says, "Who does great and unsearchable things, wonders without number. He gives rain on the earth and sends water on the fields". Job calls the giving of rain a great wonder of God.
I was reading today from a book by John Piper who gave some facts concerning rain. For us to get rain here in San Antonio we need water to come about 150 miles to San Antonio from the Gulf of Mexico. Have you ever given thought to how much water weighs? Well, if one inch of rain falls on one square mile of land here in the city of San Antonio that would be 27,878,400 cubic feet of water, which is 206,300,160 gallons, which is 1,650,501,280 pounds of water.
That is a lot of weight over our heads when we are sleeping at night. How did that much water get up in the sky? It got there by evaporation. What is evaporation? It means that the water stops being water for a while so it can go up and not down. How does it come down? It comes down by condensation. What is condensation? The water starts to become water again by gathering around little dust particles between .00001 and .0001 centimeters wide. That is small.
Also remember there is salt in the water? Our water comes from the Gulf of Mexico, so somehow we have to get the salt out so the water will not kill all of our trees, flowers, and grass. The sky picks up close to 2 billion pounds of water from the Gulf of Mexico, carries it about 150 miles (in the process removes the salt) and then later dumps it on our city.
Well, it doesn't dump it. If the sky dump close to 2 billion pounds of water on one square mile of our city - there would be nothing left - our homes, businesses, and churches would be crushed. So the sky dribbles the couple of billion pounds of water in little drops. And they have to be big enough to fall for one mile or so without evaporating, and small enough to keep from crushing our trees, flowers, and grass.
How do all these microscopic specks of water that weigh a couple of billion pounds get heavy enough to fall? It's called coalescence. Coalescence means that the specks of water start bumping into each other and join up and get bigger, and when they are big enough, they fall.
Now there is even more to it than my mind can begin to understand. That is why I like Job's words about rain.
Job 5:9-10 Who does great and unsearchable things, wonders without number. He gives rain on the earth and sends water on the fields. Job calls the giving of rain a great wonder of God.
I agree with John Piper when he says, "I think I should be thankful, a lot more thankful than I am.
Thank you Lord Jesus for the rain this week!
