Consider The Clouds

READ: Job 37:1-16

Do you know how the clouds are balanced? —Job 37:16

One day many years ago my boys and I were lying on our backs in the yard watching the clouds drift by. “Dad,” one asked, “why do clouds float?” “Well, son,” I began, intending to give him the benefit of my vast knowledge, but then I lapsed into silence. “I don’t know,” I admitted, “but I’ll find out for you.”

The answer, I discovered, is that condensed moisture, descending by gravity, meets warmer temperatures rising from the land. That moisture then changes into vapor and ascends back into the air. That’s a natural explanation for the phenomenon.

But natural explanations are not final answers. Clouds float because God in His wisdom has ordered the natural laws in such a way that they reveal the “wondrous works of Him who is perfect in knowledge” (Job 37:16). Clouds then can be thought of as a symbol—an outward and visible sign of God’s goodness and grace in creation.

What is relative humidity and how does it affect how I feel outside?

If the air is at 100-percent relative humidity, sweat will not evaporate into the air. As a result, we feel much hotter than the actual temperature when the relative humidity is high.

Humidity is somethi­ng we hear about daily in weather reports. Humidity is to blame for that muggy, steam-room feeling you experience on certain summer days.

Humidity can be measured in several ways, but relative humidity is the most common. In order to understand relative humidity, it is helpful to first understand absolute humidity.
