Engineering Joint Lubrication

In our rapidly modernizing world, engineers are kept busy solving problems. Take, for example, all of the various kinds of transportation. There are millions of problems in this area alone that keep engineers busy inventing better solutions.

Freight trains carry enormous loads in huge freight cars, each one capable of carrying the weight of the average home and everything in it, plus an automobile. Yet the axles must be able to swivel easily beneath the car as the train moves along tracks that swerve left and right. Consider the problem of setting 100 tons or more on a swivel without hindering the free movement of the swivel. Engineers at Shell Oil finally designed a disc that is placed beneath the body of the car to lubricate the axles for swiveling. Whenever the disc is squeezed by the weight of the load above or from too much friction in swiveling, lubrication automatically squirts out of the disc.

It is this same ingenious system that lubricates certain joints in your body. When additional lubrication is needed in a joint, tiny discs release lubricant into the joint. These discs are called bursae. And if you have ever had bursitis, you know what happens when the discs aren’t working properly.

It’s not science but faith in evolution that leads people to believe that this well-engineered system could be the result of accidental mutations.

Joshua 24:15
“And if it seem evil unto you to serve the LORD, choose you this day whom ye will serve… But as for me and my house, we will serve the LORD.”

I thank You, Lord, that You have designed my body in such a wondrous fashion. Help me to take good care of it, and grant me good health and strength to be used in service to You. Amen.
