Like life, the physics lab can be a noisy place. The test instruments all clank and bang and give off the sounds of friction, resistance, force, power, energy, lift, drag, velocity, and all the other testing parameters. There are fulcrums, inclines, pulleys, weights, levers, transistors, electrical meters, and other gadgets designed to prove the physical laws God calibrated into His creation. Bump and grind go the mechanics of our world, visibly displayed. They somehow make all the mathematical formulas and calculations more comprehensible.
Over them all is the constant whirring of another machine. It is a slight hum, the mmmmmmm of all of the physics functioning in proper order. It is plugged into an electrical outlet and the power surges through it's wires to the inner mechanism. An electrical motor runs deep inside the machinery. A fan operates almost silently. It is the air-conditioning unit over in the corner. It's motor forces cooled air from it's vents at three speeds. The amps and volts and ohms over-ride the resistance of hot air and sends the coolness in a stream throughout the room. Thermo-dynamics converts the the warm air into a temperature that is set on the mechanism. It blows at three determined speeds. Wow, the physics of every day life.
A lot has to happen to make the thing work. The schematic was drawn with precision by an engineer of air, an architect of coolness. We only pay attention to it when one of the machine parts malfunctions and the flow of air is interrupted. Then it makes some noise, maybe puffs smoke, even fills the air with a fowl odor, a breakdown in the physics. One of the components, perhaps many, aren't working properly. Now we're sweating. So, we may bang on the lid, give the outer covering a swift kick, switch the power on and off, try un-plugging and re-plugging.
Eventually, we'll most like call a specialist to regain efficient operation and cool air again, someone trained in repairing these things. With precision and delicacy they will identify the problem, present solutions, replace or repair broken parts, and get the thing moving again as soon as possible. You know, you can't live without air these days.
The physics of church, and of life, naturally, break down occasionally too. Sometimes we can make minor adjustments to reactivate the machinery. Other times, a specialist is required. We can consult the ultimate physics text, the Bible, for instruction. There may need to be some re-wiring, cleaning of the lines, re-attachment of contacts, smoothing of surfaces, elimination of resistance, polishing some friction, or other calibrations. But, the machinery, that is, the human body, the heart and mind for human relationships, the church too, are very fine equipment, designed with great care. When the connections are right, the angles properly set, the connections rightly made, and the instructions are followed as designed, this machinery works well too.
Over the noise of the lab we hear mmmmmmmm!
Pray that it is so.
