Proverbs 25 8-25-22

If human fingers are simple, then why can’t scientists come up with even a two-dimensional version that works?

2 It is the glory of God to conceal a matter; to search out a matter is the glory of kings [humans].

As we continue our study on the index finger, this information is from, “A Pocket Guide to the Human Body,” pages 84-85.

The finger’s tendons and ligaments have rightly been described as a complex, dynamic “net” that constantly shifts position in response to the multiple forces acting upon it. Shifting the index finger from one computer key to another requires little conscious effort, but such activity demands simultaneous processing of hundreds of thousands of electrical signals. Nerve cells within the spinal cord receive signals from sensors in the hand that detect motion, stretch, and position. This information, together with visual input from the eyes, enables the nervous system to make instant calculations about the finger’s current position in space and immediately send new commands to multiple muscles to alter the finger’s position.

Digital signal processing did not originate with computers. It has been a part of our makeup since God created the first man, Adam. The monitoring system in our spinal cord and brain stem far surpasses anything humans have yet devised. By elaborate biochemical processes, sensors in the hand fire volleys of on-off signals to update the central nervous system about the hand’s status. This control system, which rapidly assesses incoming data from thousands of sources and then directs selected motors to respond, is apparently encoded in our DNA before birth. This “software” enables us not only to process a continuous stream of data but also to write new software subroutines that help us remember new finger motions as we practice them, whether learning to type or to play a musical instrument.

Effective functioning of the index finger requires not only well-orchestrated muscles, tendons, and nerves but also efficient processes to regulate blood flow, temperature, wound repair, growth, and immunity to diseases. The list goes on and on.

Tomorrow, we look at an unsung hero. It will also be our last study of the human body. Sadness…

Abba, even as I type feverishly on my keyboard, I praise You for making me so fearfully and wonderfully, as well as every human ever born. Even though You have new bodies awaiting us in Your kingdom (heaven), these earth-suits are quite resilient. Thank You for this study. It has been quite educational as well as leading us to praise You and give You thanks. I am reminded to love my neighbor as I love myself. Knowing the way I am made helps me realize how much YOU love me; therefore, I am free and feel released–even empowered–to love others. May You receive all the glory, Lord. Amen.
