9, 10. (a) Jehovah demonstrates what type of wisdom, and how has he displayed it? (b) How does the cell give evidence of Jehovah’s wisdom?

⁹ Have you ever marveled at the ingenuity of a craftsman who makes beautiful things that work well? That is an impressive type of wisdom. (Exodus 31:1-3) Jehovah himself is the Source of and the ultimate Possessor of such wisdom. King David said of Jehovah: “I praise you because in an awe-inspiring way I am wonderfully made. Your works are wonderful, I know this very well.” (Psalm 139:14) Indeed, the more we learn about the human body, the more we find ourselves awed by Jehovah’s wisdom.

¹⁰ To illustrate: You started as a single cell​—an egg cell from your mother, fertilized by a sperm from your father. Soon, that cell started to divide. You, the end product, are made of some 100 trillion cells. They are tiny. About 10,000 average-sized cells would fit on the head of a pin. Yet, each one is a creation of mind-boggling complexity. The cell is far more intricate than any man-made machine or factory. Scientists say that a cell is like a walled city​—one with controlled entrances and exits, a transportation system, a communications network, power plants, production plants, waste disposal and recycling facilities, defense agencies, and even a sort of central government in its nucleus. Furthermore, the cell can make a complete replica of itself within just a few hours!

11, 12. (a) What causes the cells in a developing embryo to differentiate, and how does this harmonize with Psalm 139:16? (b) In what ways does the human brain show that we are “wonderfully made”?

¹¹ Not all cells are the same, of course. As the cells of an embryo continue to divide, they assume very different functions. Some will be nerve cells; others bone, muscle, blood, or eye cells. All such differentiation is programmed into the cell’s “library” of genetic blueprints, the DNA. Interestingly, David was inspired to say to Jehovah: “Your eyes even saw me as an embryo; all its parts were written in your book.”​—Psalm 139:16.

¹² Some body parts are immensely complex. Consider, for example, the human brain. Some have called it the most complex object yet discovered in the universe. It contains some 100 billion nerve cells​—perhaps as many as the number of stars in our galaxy. Each of those cells branches off into thousands of connections with other cells. Scientists say that a human brain could contain all the information in all the world’s libraries and that its storage capacity may, in fact, be unfathomable. Despite decades of studying this “wonderfully made” organ, scientists admit that they may never fully understand how it works.

13, 14. (a) How do ants and other creatures show that they are “instinctively wise,” and what does that teach us about their Creator? (b) Why might we say that such creations as the spiderweb are made “in wisdom”?

¹³ Humans, however, are just one example of Jehovah’s creative wisdom. Psalm 104:24 says: “How many your works are, O Jehovah! You have made all of them in wisdom. The earth is full of what you have made.” Jehovah’s wisdom is apparent in every creation around us. The ant, for example, is “instinctively wise.” (Proverbs 30:24) Indeed, ant colonies are superbly organized. Some ant colonies tend, shelter, and draw nourishment from insects called aphids as if these were livestock. Other ants act as farmers, raising and cultivating “crops” of fungus. Many other creatures have been programmed to do remarkable things by instinct. A common fly performs aerobatic feats that the most advanced of man’s aircraft cannot duplicate. Migrating birds navigate by the stars, by the orientation of the earth’s magnetic field, or by some form of internal map. Biologists spend years studying the sophisticated behaviors that have been programmed into these creatures. How wise, then, the divine Programmer must be!

¹⁴ Scientists have learned much from Jehovah’s creative wisdom. There is even a field of engineering, called biomimetics, that seeks to mimic designs found in nature. For instance, you may have gazed in wonder at the beauty of a spiderweb. But an engineer sees it as a marvel of design. Some frail-looking strands are proportionately stronger than steel, tougher than the fibers in a bulletproof vest. Just how strong? Imagine a spiderweb enlarged in scale until it is the size of a net used on a fishing boat. Such a web could catch a passenger plane in mid-flight! Yes, Jehovah has made all such things “in wisdom.”

15, 16. (a) The starry heavens give what evidence of Jehovah’s wisdom? (b) How does Jehovah’s position as Supreme Commander over vast numbers of angels testify to the wisdom of this Administrator?

¹⁵ Jehovah’s wisdom is evident in his works throughout the universe. The starry heavens, which we discussed at some length in Chapter 5, are not scattered haphazardly throughout space. Thanks to the wisdom of Jehovah’s “celestial laws,” the heavens are beautifully organized into structured galaxies that, in turn, are grouped into clusters that, in turn, combine to form superclusters. (Job 38:33, The New Jerusalem Bible) No wonder that Jehovah refers to the heavenly bodies as an “army”! (Isaiah 40:26) There is another army, though, that even more vividly demonstrates Jehovah’s wisdom.
