Micro Marvels of the Human Eye
“Jesus answered and said unto them, Go and shew John again those things which ye do hear and see: The blind receive their sight, and the lame walk, the lepers are cleansed, and the deaf hear, the dead are raised up, and the poor have the gospel preached to them.”
The tiny computer chip – the basis of modern computers – is a thin wafer of silicon only about 7 millimeters across – about one fourth of an inch. This tiny chip might have the equivalent of 100,000 transistors built into it. Despite its size, hundreds of connections might be attached to it. The design of the computer chip is a marvel surpassed only by the amazing technology that can build it.
If you were to find a silicon chip laying in the silicon sand at the beach (which would be quite an accomplishment because they are so small!), you would never be able to convince even one engineer that the chip had formed through the chance movements of all that silicon based sand!
Now consider the human eye. The retina at the back of the eye is a very thin membrane, much thinner than even the clingiest food wrap. This retina contains not transistors but much more sophisticated photo receptors, each of which is a high gain amplifier. The retina doesn’t have 100,000 of these, but rather it has 200,000 for each square millimeter of retina!
But the greatest wonder of all is how any scientist can say that your miraculous eye is the result of unguided genetic mistakes that, just by chance, resulted in the eye. Indeed, God’s fingerprints are all over the creation, just as our human work is seen in the computer chip. How can one who can design only the computer chip dare question the One who can design the eye – and so much more?!
Heavenly Father, just as man’s most creative technology is nothing compared with what You have made, so must I rely entirely on what Your Son, Jesus Christ, has done for me so that I may have the forgiveness of sins. Thank You. In His Name. Amen.
