My friend bought an old, but low mileage, cute Volkswagen Bug. But this car had sat immobile for too long. Almost immediately, the car’s fuel pump failed. Next, the water pump failed. Soon, the belts failed. And so on. Our bodies are very much like that little Bug. If we don’t use them, we lose them, so to speak. They do not function at their best. “Fearfully and wonderfully” God designed our bodies (Psalm 139). And when we use them by moving (exercising) them, the way God designed, our bodies are amazing. However, if we sit, just like this poor car sat, they fail to be all they can be.
