Chaplain Jesse of Truckstop Ministries explains a spiritual truth by employing a practical example: "Life without joy is like a vehicle without shock absorbers. A vehicle's shock absorbers are designed to cushion the vehicle from unexpected bumps in the road. Without them, the vehicle would fall apart from the violent blows encountered during its travels.
People are often the same way.
As we travel on the road of life, most of the time we are not looking for bumps or potholes. So when they suddenly show up, we're not ready for them. The Holy Spirit — our God-given 'shock absorber' — cushions the blow until we can readjust and adapt our thinking to accommodate the sudden change in the ride. Joy is to life what shock absorbers are to vehicles. It won’t take the potholes out of the road, but it sure makes the ride smoother. Laughter and joy are the shock-absorbing cushions of life and can radically change our perspective."
John 16:33 " ... but be of good cheer; I have overcome the world." (KJV)
