Have you ever wondered if air has weight? It does! That is the reason you can feel the wind blow against your face on a windy day. Air can be heavy depending on the temperature and the altitude of your location. If you are standing on the top of a mountain, the air will weigh less than it would at a lower elevation. In fact, air pressure at sea level is almost 15 pounds per square inch!
Why aren’t people crushed under the weight of air? It’s because God designed the human body to withstand that kind of pressure. God even made our lungs to contain roughly the same air pressure as the air outside our bodies.1

Wind can be quite a destructive force. The Bible says that everyone who listens to and obeys the Word of God is like a wise man who built his house upon a rock foundation. “The rain came down, the streams rose, and the winds blew and beat against that house; yet it did not fall, because it had its foundation on the rock” (Matthew 7:25). This is in contrast to a foolish man who built his house on the sand. The wind and rain beat against the foolish man’s house and it fell, because sand is not a strong foundation. What kind of spiritual foundation are you building? Will it withstand the winds of life? To learn about building a strong spiritual foundation of rock, please read the good news.
