Ken Davis & The Law of the Pendulum

Just read a review of Lord, Save Us from Your Followers. I saw a screening of the movie a couple weeks ago. The review addresses one of the thoughts I had after seeing the movie... the idea of churches in America sort of going back and forth in terms of trends, emphasis, etc. The word "pendulum" came to mind.

Several years ago I heard Ken Davis tell this very funny, yet poignant story about the Law of the Pendulum. Below is an excerpt from his book - How to Speak to Youth ... and Keep Them Awake at the Same Time - and tells that story in his own words.

In college I was asked to prepare a lesson to teach my speech class. We were to be graded on our creativity and ability to drive home a point in a memorable way. The title of my talk was, “The Law of the Pendulum.” I spent 20 minutes carefully teaching the physical principle that governs a swinging pendulum. The law of the pendulum is: A pendulum can never return to a point higher than the point from which it was released. Because of friction and gravity, when the pendulum returns, it will fall short of its original release point. Each time it swings it makes less and less of an arc, until finally it is at rest. This point of rest is called the state of equilibrium, where all forces acting on the pendulum are equal.

I attached a 3-foot string to a child’s toy top and secured it to the top of the blackboard with a thumbtack. I pulled the top to one side and made a mark on the blackboard where I let it go. Each time it swung back I made a new mark. It took less than a minute for the top to complete its swinging and come to rest. When I finished the demonstration, the markings on the blackboard proved my thesis.

I then asked how many people in the room BELIEVED the law of the pendulum was true. All of my classmates raised their hands, so did the teacher. He started to walk to the front of the room thinking the class was over. In reality it had just begun. Hanging from the steel ceiling beams in the middle of the room was a large, crude but functional pendulum (250 pounds of metal weights tied to four strands of 500-pound test parachute cord.).

I invited the instructor to climb up on a table and sit in a chair with the back of his head against a cement wall. Then I brought the 250 pounds of metal up to his nose. Holding the huge pendulum just a fraction of an inch from his face, I once again explained the law of the pendulum he had applauded only moments before, “If the law of the pendulum is true, then when I release this mass of metal, it will swing across the room and return short of the release point. Your nose will be in no danger.”

After that final restatement of this law, I looked him in the eye and asked, “Sir, do you believe this law is true?”

There was a long pause. Huge beads of sweat formed on his upper lip and then weakly he nodded and whispered, “Yes.”

I released the pendulum. It made a swishing sound as it arced across the room. At the far end of its swing, it paused momentarily and started back. I never saw a man move so fast in my life. He literally dived from the table. Deftly stepping around the still-swinging pendulum, I asked the class, “Does he believe in the law of the pendulum?”

The students unanimously answered, “NO!”

Davis' point is this: don't listen to what people say about their faith, watch what they do. My thought, as related to Lord, Save Us from Your Followers and trends in the Church, is that the Church shouldn't mimic the pendulum, i.e., it's primary emphases shouldn't swing from one side to another in reaction to cultural trends and generational preferences. Rather, just as the pendulum is in perfect equilibrium while in its static state (resting still in the middle), the Church will find perfect biblical balance while while resting on the perfectly balanced truth of Christ... grace AND truth. We tend to go back and forth. Grace. No, no, no. Truth. No, no, no. Grace. No, no, no...

John 1:14 says, the Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father, full of grace and truth.

The perfectly balanced message of the Church? Grace and Truth. One without the other is an incomplete, inaccurate picture of Christ. One without the other leads us and others astray. One without the other can never truly transform a life.
