Your Skin Holds Everything Together

You can go online and get all the factual information you want on every part of the human body. Put in the word “skin,” and you will be amazed at how much information there is about human skin. One comic said, “Your skin holds everything together.” In truth, it does much more than that.

We tend to classify humans based on their skin color, but our skin color is related to the needs of the body. Black objects radiate heat more efficiently than white objects. Take two identical cans and paint one black and the other white. Heat them to the same temperature and then let them sit in an insulated environment. The black can will cool off faster than the white can. Dark skin color is due to a biological pigment called melanin. Melanin absorbs ultraviolet light and thus protects the body. People living in tropical areas where they are exposed to more heat and ultraviolet light have more melanin than people living in cooler regions. There is, therefore, a latitude effect on skin color.

The more you study the design of your skin, the more amazing it is. One square inch of human skin contains nearly 20 million cells and 625 sweat glands. That square inch of skin can also have as many as 65 hairs, 19 feet (5.8 meters) of blood vessels, and 19,000 sensory cells. To limit bleeding, blood vessels in your skin temporarily shrink instantly if the skin is cut or if pressure is applied. Your body sheds skin cells when they die and replaces them with new ones. Three-quarters of the dust floating around your house is made up of dead skin cells.

So, if you think your skin holds everything together, and that’s all, you would be wrong. Your skin, the largest organ in your body, does a wide range of things that help you to stay alive and comfortable. When David wrote, “I will praise you, God, for I am fearfully and wonderfully made” (Psalms 139:14), he was not aware of many things about our bodies that we know today. As we look at ourselves with tools such as microscopes, we see design in the construction of our bodies that David could not have imagined.

There is a wonderful book published in 1989 and now out of print that gives many other examples of the incredible designs we see in our bodies. The title is The Compass in Your Nose and Other Astonishing Facts About Humans by Marc McCutcheon and published by Jeremy Tarcher, Inc.

Why Do We Need Insects?

Many years ago, while working in a teen camp in Alaska, I heard a skeptical teenager disparage God’s existence by saying that if God existed, He certainly wouldn’t have made mosquitoes. I have heard similar comments about ticks, hornets, lice, locusts, spiders, and stink bugs. I suspect we have all had times when we were unhappy with annoying bugs, yet when you examine the role of insects, you realize they are critical to our own existence. The well-known entomologist E. O. Wilson said, “If human beings disappeared tomorrow, the world would go on with little change, but if invertebrates were to disappear, I doubt the human species could last more than a few months.” Why do we need insects?

Insects pollinate plants, aerate and fertilize the soil, decompose dung, and the bodies of things that have died. They control pests contributing 70 billion dollars every year to our national economy. Ninety-six percent of land-dwelling birds feed their young on insects, consuming approximately 400 to 500 million tons of insects. Most creatures in and around lakes and streams feed on insects, including fish and bears.

Why do we need insects? Humans are already seeing the cost of eradicating them. There are 68 species of bumblebees and roughly a fourth of those are in danger of becoming extinct. In Europe, the data shows a 76% drop in insects, including bees, beetles, lacewings, and katydids. The loss of pollinating insects has sharply affected the growing of many cash crops, and scientists are studying the effects of insecticide use.

Before we castigate God for what He has created, we need to be sure we have all the facts. We should learn what each creature does and how it contributes to our own well being. I dislike mosquitoes as much as the next person, but a majority of mosquitoes are pollinating insects. I am reactive to a bee sting, but bees contribute to much of what I eat. From our earliest existence, God has challenged us to take care of what He created. (See Genesis 2:15.) That includes caring for and protecting the agents that allow Earth to be hospitable to our existence.

Memorial to Help Us Remember

By definition, we establish a memorial to help us remember certain essential things. Memorials are very much a part of Christianity and of the history of Israel. Members of different denominations have instituted all kinds of special days and given them spiritual significance. In reality, those days are not found in the Bible, and there is no biblical command to observe them. Perhaps God knew that humans would corrupt special days and forget their significance and message. Christmas is an example of that.

In Exodus 3:15, God told Moses that the exodus from Egypt would be a “memorial to all generations.” Jesus spoke in Mathew 26:13 of a memorial for the woman who anointed him for burial. In Luke 22:19-20, Jesus gave His followers the one special memorial to observe. Early Christians met on the first day of every week to remember Christ’s body “which is given for you” as they ate the bread and drank the fruit of the vine–“the new testament in my blood which is shed for you.” Even though Jesus gave us this memorial to help us remember, it was very quickly corrupted. In 1 Corinthians 11:20-34, we read that it had become a drunken feast in the Corinthian church. The memorial’s purpose was lost because they were “not discerning the Lord’s body” (verse 29). Paul goes on in this description to say, “this is why many are weak and sickly among you, and many sleep” (verse 30).

Today in the United States, we celebrate Memorial Day. The last Monday in May was made a national holiday in 1971 to honor the memory of those who died to defend America from those who would try to destroy us. It seems that each year there is more emphasis on this day being the “unofficial first day of summer” with little emphasis on its intended meaning. Like the words of 1 Corinthians 11, this day has become a drunken feast for many, and our population is weak and sickly as a result. Many of us are more concerned with Memorial Day sales and, in 2020, how to celebrate without getting the virus than with pausing to give thanks for America and for those who died to preserve it.

As Christians, we have one special memorial to help us remember the sacrifice Jesus made. Even as we stop every week to remember what Jesus did for us, we must develop an attitude of gratitude. As we thank God who sent His Son to die for our salvation, we should also remember those who died to keep us free to worship in this country.

Bird Droppings and Waste Disposal

If you ever found your car looking like the one in the picture, you know how frustrating it can be. Maybe you should have parked in a different spot. Seriously, bird droppings and waste disposal by all animals present many design challenges.

One of the major issues for all living things is how to dispose of waste. Left inside the body, waste products can be toxic. Surviving the toxic effect can be a significant challenge for a hibernating bear. For birds, it becomes complicated because they must remain lightweight to fly. They cannot have a waste removal system that is heavy or dense. That means there is no bladder and no elaborate intestinal tract in birds.

God has designed a system of waste removal in birds that we are all aware of, but may have never considered carefully. The next time you see bird droppings on your car or the sidewalk, take a close look. You will see that there is a dark spot surrounded by white material. The dark spot is fecal matter, and the white stuff is urine. The urine washes away quickly in the first rain, and the fecal matter remains. Waste removal systems frequently benefit other forms of life, and that dark spot may contain seeds that contribute to the spreading of plant life.

Some birds have unique disposal systems such as owls, which make pellets out of solid material they eat, including bones. The birds that decorate your car are specially adapted to flight. The design of their disposal system allows them to be rulers of the sky. Birders are probably familiar with a periodical put out by a humorous writer who called himself Dick E. Bird. Years ago, he wrote this poem to explain how birds defecate:

“Birds, ya know, don’t got no bladder,
So wherever they is, it just don’t matter.
On the deck or on the sills,
The spirit moves, you hear a trill.
Then they fly, just like a thief,
That is how they spell relief.”

God intelligently designs every living system, and waste disposal systems are no exception. Bird droppings and waste disposal from animals also require clean-up after the fact, and God has that covered too, as we have discussed before.

Hitler and Richard Dawkins

We see a similarity between the writings of Hitler and Richard Dawkins. In 1941 Adolph Hitler, in his book Table Talk wrote:

“Today war is nothing but a struggle for the riches of nature. By virtue of an inherent law, these riches belong to him who conquers them. That’s in accordance with the laws of nature. By means of the struggle, the elites are continually renewed. The law of selection justifies this incessant struggle, by allowing the survival of the fittest. Christianity is a rebellion against natural law, a protest against nature. Taken to its logical extreme, Christianity would mean the systematic cultivation of human failure.”

Richard Dawkins has written:

“This is one of the hardest lessons for humans to learn. We cannot admit that things might be neither good nor evil, neither cruel nor kind, but simply callous-indifferent to all suffering, lacking all purpose.”

Both Hitler and Dawkins have attacked Christianity based on morality. If there is no such thing as good or evil, as Dawkins has written elsewhere, and if natural selection is the law we all live by, then survival depends on who is fit and who is not. In that case, there is no way to justify Christ’s teachings in the Sermon on the Mount or the content of Matthew 25. It means that we are all doomed to violence, suffering, and war. Dawkins would suggest that we should be indifferent to the atrocities of humans destroying other humans. It isn’t easy to see how Hitler and Richard Dawkins would disagree philosophically.

Atheism is both a philosophy and a religion. It is hard to believe that after a person looks at the history of atheism, they would deny God’s existence. The atheist, however, would point to religious wars as a demonstration that religion doesn’t do any better than Hitler’s beliefs. That is why this ministry does not defend any religion that can be defined as “human attempts to reach God.” This ministry only claims that there is evidence for God’s existence and that applying the teachings of Jesus Christ would bring peace and well-being to all of humanity.

Adolph Hitler and Richard Dawkins share the same perspective. Hitler claimed that Christianity cultivated human failure. Atheism claims life is purposeless, and by Dawkins’ admission, life cultivates violence and war. That is the fulfillment of what Hitler called “the law of selection.” The contrast between Christianity and atheism is crystal clear when we read the writings of Hitler and examine the history of his application of atheistic beliefs.

Nitrogen Fixation and Life

There are many chemical wonders in our world, but few are as important and complex as the chemistry of nitrogen. Nitrogen makes up 78% of our atmosphere. It combines with oxygen to form nitrates and with hydrogen to produce ammonia, both of which are essential for growing our food. Nitrogen fixation, which is how nitrogen gets from what we breathe to what we eat, is an amazing demonstration of design.

First, let us review a little high school chemistry. The atoms of all elements have electrons which give them their properties for forming compounds. The electrons are arranged in pairs with their magnetic poles designed so that in a stable arrangement, one electron’s north pole is matched with its neighboring electron’s south pole. The electrons have various orbitals with different energy levels. The atom is stable and chemically inert if an orbital is filled with all the paired electrons it can hold. For example, neon has 10 electrons. The first two orbitals each have two paired electrons, and the last orbital has six electrons in three pairs. This pairing of electrons makes neon an inert gas which does not combine chemically with other elements.

Nitrogen has an uneven number of seven electrons. So how does nitrogen become chemically stable? The answer is that two nitrogen atoms share three electrons, giving them stability. The two nitrogen atoms bond together to form a diatomic molecule that cannot be easily pulled apart to bond with other elements. How strong is the bonding? To break up a nitrogen molecule into two nitrogen atoms requires temperatures of 400 to 500 degrees Celsius and pressures of 200 atmospheres. So with nitrogen as the dominant element in our atmosphere, the atmospheric gases are stable and inert. Also, nitrogen is not a greenhouse gas that could threaten our temperatures on Earth. How then has God built a system that takes these stable nitrogen molecules and breaks their triple bonds to produce nitrates and ammonia?

If you think this isn’t an important subject, ask yourself where your food comes from? The answer is that 50% of the American diet is produced using artificial fertilizers containing nitrogen, which has been “fixed.” Nitrogen fixation combines that inert gas with oxygen and/or hydrogen to supply the soil with the chemical needed to grow the plants we eat, and which the livestock eat to provide us with meat.

Bacteria accomplish God’s method of nitrogen fixation. The bacteria turn nitrogen into ammonia, which is a nitrogen atom sharing electrons with three hydrogen atoms instead of with another nitrogen atom. Plants known as legumes such as soybeans and peas, as well as bayberry and alder trees, attract bacteria which concentrate in nodules on the plant’s roots. The bacteria turn nitrogen gas into ammonia and nitrates the plants can use. Cyanobacteria in the ocean and cycad plants on the land are also major nitrogen fixers. Scientists are also discovering tropical plants that contribute to the wealth of nitrogen compounds in the soil.

Most of our fertilizers have nitrogen fixed by a method called the Haber-Bosch process. It uses massive amounts of energy to break the triple bonds of nitrogen gas. Producing 500 degrees and 200 atmospheres is expensive, and that is why you pay so much for the fertilizer you use in your garden. God’s methods are free. Scientists are trying to figure out how to recreate God’s nitrogen fixation method to save energy and produce more food.

Many bacteria are beneficial in various ways, and nitrogen fixation is only one of them. This is a great apologetic for God’s wisdom and design in preparing the Earth to provide food for us to eat.

Religious Anti-Science Rhetoric

For the 51 years of this ministry, we have confronted religious anti-science rhetoric. Our critics are those who feel that science is an enemy and that you can’t be a good Christian and embrace science. We are now in a period when the issue of whether people can meet together for worship services has become an issue of science and politics. Some politicians oppose churches resuming worship services saying there is strong scientific evidence that it will expose participants to the COVID-19 virus. Many religious leaders insist that this is an attempt by the government to restrict religion. They say that this scientifically-based objection is destroying the right of people to worship together.

In previous articles, we have pointed out that a great deal of ignorance is involved in rejecting science. According to the dictionary, science is knowledge. Knowledge is always neutral. The critical thing is how we use it. When new scientific knowledge gave us lasers, the question was how we would use lasers. Would they be weapons that cause massive destruction, or would they be medical tools to heal eyes?

We now understand how the COVID-19 virus spreads from one person to another. Will we use this knowledge to stop the progression of the illness, or will we use this virus to destroy whole masses of people? The bubonic plague from 1347-1351 killed 200 million people, which was nearly half of Europe’s population. Religious anti-science rhetoric today has the potential to create a catastrophe.

It isn’t our knowledge about the COVID-19 virus that is a threat to freedom or to worship. The reality is that science will eventually develop a vaccine that will allow everyone to worship together. Smallpox was killing 400,000 people a year in Europe, and it only stopped when scientists developed a vaccine. It is hypocritical for religious people to vilify science while they: 1) enjoy modern technology in their entertainment 2) go to medical facilities for treatment of disease, 3) use scientific advancements to grow and prepare their food, 4) use new scientific discoveries in their businesses, and 5) use science in their homes to improve their standard of living.

Proverbs 8 makes it clear that God has used science (wisdom) in all He has done. Psalms 19 and 139 refer to God’s creation, and Romans 1:19-20 points out that science reveals God’s existence through the things He has made. The following verses, Romans 1:21-32, point out that human moral and political choices cause the pain and destruction we see in our world.

Christianity doesn’t need to violate social distancing to worship and to practice our faith. James 1:27 defines true religion, and Jesus made it clear that He is there when just two people come together in His name (Matthew 18:20). First Timothy 6:20 tells Christians to avoid scams and religious claims called science. Ignore the religious anti-science rhetoric and know that God and science are friends. Don’t listen to politicians and religious hucksters and rely on evidence and the message of proven researchers. Join together in prayer and worship in our homes on Zoom, YouTube, Facebook, or whatever method you choose. Rejoice that, through science, God has given us new ways to come together, encourage each other, and glorify Him even in the middle of a pandemic.

Strong Enough to Bend

In 1988 Tanya Tucker had a country song titled “Strong Enough to Bend” that had a great message. In the song, she compared a willow tree to human relationships. She pointed out that willows can survive because their limbs can bend instead of breaking.

Interestingly enough, that concept is present in most living things in the creation. God rarely uses stiff materials in what He creates. On the other hand, humans tend to use rigid materials such as metals, ceramics, dry wood, etc. In your own body, how many stiff materials are there? Bones and teeth are about it. These are components designed for a specific purpose where hardness and stiffness are required. Most things in the biological world are soft, not brittle.

A classic example of the benefit of being soft and not hard is kelp and other marine algae. Those plants live in the violent world of surf. If you have ever surfed, you know the power of waves. I have seen surfboards thrown against rocks, pounded by the waves, and turned into a pile of shredded plastic in a matter of minutes. Kelp live in the surf with one end attached to rocks and the surface of the plant exposed to sunlight for photosynthesis. Kelp can survive because they are strong enough to bend.

Waves produce flows that reverse direction every few seconds. As soon as the plant grows longer than the distance the local water travels between reversals, the additional length of plant material is swept back and forth with the water. The plant literally goes with the flow. Since it moves the same direction as the water and at the same speed, there is no friction between the plant and the water. Kelp can grow to lengths well over 130 feet (40 m). A rigid plant like an oak tree in the surf would be pounded to splinters in a few hours.

Closer to home for most of us, are the leaves of land plants. Take a cardboard tube like a paper towel tube and try to bend and twist it. Then make a lengthwise slit in the tube and try it again. Notice how much easier it is after you cut the tube. The reason leaves have exotic shapes is to allow them to bend and twist rather than breaking in high winds or creating wind resistance that would take down the tree.

This design shows highly complex engineering, and our lives exist because of it. Imagine what would happen if our skin, eyes, ears, stomach, blood vessels, hair, etc. were not made of soft, pliable material. A good sneeze could shatter our face! Our Creator knew that being strong enough to bend was critical for our existence.

How Do Sea Animals Drink Water?

Yesterday we discussed how fish drink water. In the ocean, the problem isn’t water but salt. Ocean fish are designed with specialized gills that support the kidneys in getting rid of salt accumulations that would otherwise pickle the fish. Obviously, not all animals that live in the ocean have gills. How do sea animals drink water?

Albatrosses and petrels are birds that can spend a year or more in the open ocean, but they need to drink water. Whales and seals also do not have land-based water supplies, and yet, like all mammals, they need water to survive. So how do sea animals drink water when ocean water is salty? God’s design of living creatures always includes unusual equipment to enable them to deal with their environment.

In the case of sea birds, they have a set of salt glands in their heads that connect to the bird’s nostrils. The birds drink seawater, but the glands are so efficient that within three hours, all of the salt is removed through the nostrils.

Whales and other aquatic mammals produce urine that has extremely concentrated salt content. By allowing high salt concentrations in the urine to diffuse into the ocean, the salt never reaches toxic levels inside the animal. An interesting sidelight to this is that the milk of these sea mammals is very low in water content. In that way, they conserve water. Milk from seals has only half the water content of lean hamburger.

Everywhere we look in the natural world, we see that a wonder-working hand has gone before. These marvelous designs are not the product of mindless chance. They show an Intelligence who created with purpose and wisdom. When we realize that ocean water has high salt content, we question, “how do sea animals drink water?” God already took care of that.

In Job 38-40, God challenged Job to advance his understanding of God’s power and wisdom by considering the natural things of creation. When Job questioned God’s wisdom and purpose in his personal struggles, he did not recognize the wisdom shown in creation’s design. We too need to look at what God has done and “know there is a God through the things He has made” (Romans 1:18-20).

How a Fish Drinks Water

Have you ever wondered how a fish drinks water? Your first reaction is probably something like, “It opens its mouth.” Like most things in life, it isn’t that simple.

All living things necessarily have some saltwater content in their bodies to keep chemical balance allowing life to exist. The fluids inside an ocean-dwelling fish are only about a third as salty as the ocean itself. The water inside the fish’s body tends to leave by osmotic pressure, which is the tendency of fluids to move through membranes toward higher concentrations. To avoid this loss of water, the fish does simply open its mouth and drink seawater. But that brings large amounts of salt into the fish’s body. The salt concentration would be more than the fish’s kidneys could handle. To aid the kidneys, the gills of ocean fish are designed to expel salt, so the fish isn’t pickled by it.

In freshwater fish, the osmotic pressure is reversed, so the fluids inside the fish are saltier than the water outside. The skin of a freshwater fish is designed so that water seeps in through its skin and gills. Therefore, the fish doesn’t have to drink at all. When a salmon leaves the ocean and enters a freshwater stream, it merely stops drinking. Like freshwater fish, it depends on its skin to bring in its water needs.

Now that you know how a fish drinks water, the next question would be about other creatures that spend their time in the sea. Birds like albatrosses and petrels can spend more than a year at sea, and whales and seals live in the ocean 24/7/365. How can they avoid being poisoned by the salt? We’ll discuss that tomorrow.

God’s design of life includes fitting living things with specialized equipment to survive in every environment. Fish are remarkable creatures specially equipped for the waterworld in which they live.
