(a personal psalm)




(I will praise you;

for I am fearfully and wonderfully made:

marvelous are your works;

and that my soul knows right well.

–Psalm 139:14, King James Bible 2000)


I do praise you, oh God, for the breathtaking wonder of the human body.

You put together trillions of cells that perform a multitude of functions in one harmonious whole.




As each of us was formed in our mothers’ wombs, you carefully engineered the transformation of cells into:

  • blood vessels—an estimated 60,000 miles of them.
  • more than 600 individual skeletal muscles. Two hundred of them are required for just one step—an indication of the complexity of the muscular system.
  • organs, including the liver. Scientists have discovered five hundred functions for this highly important body part that we rarely think about.
  • The heart–strong and reliable enough to beat more than 2.5 billion times over an average lifespan.

Within each cell nucleus is the DNA double helix, just 80 billionths of an inch long, yet “comprised of chemical bases arranged in approximately 3 billion precise sequences. Even the DNA molecule for a single-celled bacterium,  E. coli, contains enough information to fill all the books in any of the world’s largest libraries.”*

Once this amazing organism called “human” begins functioning, you, oh God, orchestrate more wonder:

  • Nerve impulses travel to and from the brain at 170 miles per hour.
  • Noses (in conjunction with the brain) begin cataloging up to 50,000 scents.
  • The heart pumps the equivalent of 2,000 gallons of blood through the vessels every day.
  • The blood circulates through the body three times every minute.
  • Cell replacement must occur frequently.  Approximately 25 million new cells are being produced every second.




Yet the wonder continues. You’ve given us the power to think and reason.

  • All the grooves or wrinkles in the brain provide more surface area, which equates to more processing power within the small confines of the skull.
  • The brain is surrounded in fluid that acts like a cushion in case of impact, and as a barrier in case of disease.
  • More than 100,000 chemical reactions occur in the brain every second.
  • The brain contains billions of neurons that send electrical and chemical messages to the body. If all the neurons were lined up end to end, they’d stretch 600 miles.
  • And for each neuron there are 1000 to 10, 000 synapses.



But you, oh God, weren’t finished yet! You created within each of us wonderful and unique abilities. Just among our family you’ve designed a (n):

  • imaginative artist,
  • caring school psychologist,
  • attention-holding preacher,
  • passionate psychiatrist,
  • self-taught tech wizard, and
  • talented graphics designer

a more recent photo of the whole family!)


How glorious to contemplate, O Lord, the breathtaking wonder of how we’re made. Hearts keep pumping, lungs keep breathing, nerve impulses keep sending messages–without a single voluntary thought. Our brains are capable of learning and storing an enormous amount of information. And everything works together in perfect unity.

I cannot begin to fathom your creativity, expert engineering, and attention to detail. Even if we were identical robots, we would have to stand in awe of your holy genius.

But you have made each person unique, designed to fulfill a specific purpose.

May I live close to you in order to be transformed day by day into the one you designed me to be.

Long ago, David wrote a prayer of praise, marveling at God’s omnipresence, omnipotence, and omniscience—Psalm 139. David celebrated that God is present everywhere at the same time, he is all-powerful, and he knows all.  It’s one of my favorite psalms.

In the middle of this prayer, David says, “You created my inmost being; you knit me together in my mother’s womb. I praise you because I am fearfully and wonderfully made; your works are wonderful, I know that full well” (vs. 13-14).

Even back in 1000 B.C., David recognized that the human body is an amazing work of engineering and art. But centuries of scientific discoveries only increase our wonder as we begin to understand the intricacies of how the human body works.

One of the most amazing finds occurred in the middle of the twentieth century: the discovery of DNA, researched by Francis Crick, James Watson, Rosalind Franklin, and Maurice Wilkins.

You may recall from biology class that all living cells contain a chromosome, a single molecule of DNA bonded to various proteins. These chromosomes contain the genes that determine inherited traits. In all eukaryotic cells (those that contain complex structures enclosed within membranes), the chromosomes are thread-like strands, located in the nucleus.

75 pxThese thread-like strands form a spiraled ladder, called a double helix. One side goes up, the other goes down. “Base pairs” interlock in the middle, keeping the distance constant between the two helixes.

(If you remembered all that, you either studied biology recently or have an incredible memory! And if I have misread the research and reported the facts wrong, please set me straight in the Comments section.)

Scientists now know just how many bits of information are coded onto each chromosome: twenty billion! That amount of information would take three billion letters to record.

If the average word contains six letters, the information on one human chromosome equals about 500 million words.

If there are 300 words on a printed page, the information would require two million pages to record.

If these pages were bound into 500-page books, the resulting library would contain 4,000 books.

The human chromosome carries 4,000 large books of information!

Part of that information is to instruct each cell about its job. There are more than 200 different cell-types in the human body. DNA instructs each one how to function—as bone, muscle, organ, brain, hair, fingernails, blood vessels, etc. DNA programs all 100 trillion of each body’s cells. And every hour one billion of those cells are being replaced.

Suddenly, David’s words, “We are fearfully and wonderfully made” take on fresh meaning. We shake our heads in amazement. And we’ve only considered one tiny miracle out of thousands that occur every day within our own bodies, much less everything else happening on our planet, in the galaxy, and in the universe.

Almighty God, our hearts fill with awe and praise as we consider your infinite genius, manifested in the wonders you have made. You are the all-wise Designer of everything, a perfect God whose work is perfect.

“You are worthy, our Lord and God, to receive glory and honor and power; for you created all things, and by your will they were created and have their being” (Revelation 4:11).

We proclaim your glory and honor and power!
