God Created Two Books

How have you arrived at the belief system that governs your life? God created two books we are called to use as the basis for our lives, morals, and religious practice. Since these two books have one author, they must be complimentary and cannot conflict. It is strange that many people read one book and refuse to look at the other. That is true of both atheists and religionists.

One of the books is the Bible, and it calls us to use it as a guide for life. Second Timothy 3:16-17 states it very clearly: “All scripture is given by inspiration of God, and is profitable for teaching, for training, for guiding and for moral discipline so that the man of God may be complete and adequately equipped for all good work.” Atheists reject this book because it involves denying one of a few physical pleasures and gives a purpose in living other than survival. Living selfishly has its rewards, and that is attractive.

God created two books, and the second book is the creation itself. The Bible is full of admonitions to use the things God has created as a means of knowing truth and learning how to live a productive and rewarding life. The Old Testament calls us to use what we see in the world around us as a guide to life. The entire book of Job carries that message. Numerous Psalms call us to see God’s wisdom and design and shape our beliefs in them. (See Psalms 8:3-9; 19:1; 53:1-4; 139:14-16.) Proverbs is full of admonitions to learn from the creation. (See Proverbs 6:6; 8:1-7 and 22-36.)

In the Sermon on the Mount, Jesus used the created world as the basis of much of His teaching. (See Matthew 6:26-30; 7:16-20.) Romans 1:18 – 23 says of humans, “That which can be known of God lies plain before their eyes for God himself has made it clear to them. For those things of God which the eye can not see, ever since the creation of the world, are clearly perceived through the things that are made, and are clear to the eye of reason, even his eternal power and divine character so that men have no excuse.”

So God created two books, and it is clear why atheists do not wish to read and apply the Bible to guide their moral and spiritual lives. It is hard to understand why people who claim to believe in God refuse to look at the creation as a source of instruction and guidance. Some are too lazy to read the Bible and study its message, and others are too lazy to read the creation and learn its message. We need to read and study both books so that we can do what 1 Peter 3:15 tells us: “Revere Christ as Lord in your hearts and always be ready with your defense whenever you are called to account for the hope that is in you, yet argue gently and cautiously with meekness and respect.”

The Hippocratic Oath No Longer Used

In the past, the Hippocratic Oath was a sworn agreement made by medical students when they became doctors. It includes a promise “to share knowledge, to help the ill and not cause harm, and to never give a deadly drug or help another to use one.” Hippocrates (460 to 370 B.C.), a Greek physician known as the “father of medicine,” was concerned with the methods and ethics of medical treatment.

Hippocrates lived at the same time as Socrates, who extolled the doctor. He was in a clan known as the Asklepiads, devotees of Asklepios, a Greek god of health. They swore to the gods to keep themselves “pure and holy,” help the sick, and avoid “wrongdoing and harm to patients.” They vowed not to breach patient confidentiality, perform surgery for which they had not been trained, cause an abortion, poison, euthanize, or sexually abuse a patient.”

The Hippocratic Oath appeared in a collection of some 70 texts called the Hippocratic Corpus. By the 10th century, Christians had replaced Greek divinities in the Hippocratic Oath with the God of the Bible, and medical schools used that version until modern times. By the early 20th century, that began to change. In 1928 only 14 of 79 medical schools required their students to swear the Hippocratic Oath. No medical school in America requires it today.

In recent years, the ethics of medicine has become a major issue. Special interest groups like “Compassion and Choices” advocate for physician-assisted suicide. Laws in several states now allow doctors to prescribe lethal amounts of drugs for use in suicide.

Is the morality of a doctor important when you or a loved one are in declining health? What is the difference between a doctor who believes the body is the “temple of the Holy Spirit” (1 Corinthians 3:16) and one who believes in survival of the fittest? This is a significant issue for all of us dealing with end-of-life issues, as all eventually will.

Lightning Dynamics and St. Elmo’s Fire

As an old physics teacher, I am interested in lightning dynamics. Most of us have seen the effects of lightning and have been impressed with its power and destructive potential.

The question is, what produces lightning and its incredible power? On Earth, lightning is caused by water. If you have a steady stream of water from a faucet and bring a charged glass or plastic rod near it, the water stream will move toward the rod. The water molecule is polarized, meaning it has a positive and negative end. The charged rod attracts the oppositely charged end of the water molecule.

When warm moist air rises to form a thunderhead, it can reach velocities of 100 mph. The air cools and forms ice crystals that can become positively charged by collisions with other ice crystals. That means the lower parts of the storm cloud will acquire a negative charge. Conversely, the very bottom of the cloud will generate a positive charge as a result of the negative sections of the cloud. When this charge imbalance becomes great enough, an inch-wide stream of electrons travels between the negative and positive areas. This can be between the two layers of the cloud, the negative midsection and positive bottom of the cloud, or the ground and the positive lower parts of the cloud. This stream of electrons typically moves at 200,000 mph.

Lightning dynamics can heat the air around the stream of electrons to 50,000 degrees Fahrenheit, turning oxygen into ozone and sending out a shock wave which we hear as thunder. A tall object like a tree, a church steeple, or a lightning rod will accumulate a charge because it is closest to the charged cloud. Sometimes charges around the tall object will cause the air to glow in what is called “St. Elmo’s Fire.” That name is credited to a monk who first recorded seeing it at the top of his church and thought he was having a vision.

Lightning dynamics are very complicated and not a threat to humans unless we are careless. However, lightning has various benefits, such as producing nitrogen fixation so that plants can grow and resupplying the ozone layer, protecting us from some of the dangers coming to Earth from outer space.

Wormholes, Black Holes, and the Beginning

One of the strongest arguments for God’s existence is the fact that all evidence indicates that there was a beginning to the creation. Space and time are not eternal. If the creation began, there had to be a cause for space/time. The only way to avoid that is to show that space/time is eternal. The classic atheist argument is that if God has always existed, it is just as valid to claim that space/time has always existed. One way to support the view that space/time is eternal is to suggest that tunnels called wormholes exist between black holes in the cosmos.

The idea is that wormholes would allow matter/energy to fall into a black hole in one area of space and re-emerge in another part of space. By falling into a black hole, the conservation laws of science and the laws of thermodynamics would be invalidated. Physical laws, entropy, and all other boundaries would start over when the matter/energy emerged at the wormhole’s other end. All matter/energy in the cosmos would experience these changes through an infinite number of wormholes, and since the laws of science would be re-established, this could go on forever. In essence, this is a new version of last century’s oscillating universe theory.

Science fiction writers have used this idea as a way for aliens to quickly travel anywhere in the cosmos. The distances between galaxies are in the millions of light years, so traveling even at the speed of light would take millions of years. If wormholes connected the galaxies, you could take a shortcut traveling instantly from one galaxy to another. This is an imaginative proposal, but the evidence doesn’t support it.

If every galaxy is connected to other galaxies by wormholes, we should be able to see matter/energy emerging from every galaxy we observe. If the wormhole were in empty space, you would see white holes where this would be happening. We don’t see any such objects anywhere. Instead, we see black holes and even have photographic evidence of their existence. However, the nature of a black hole is that matter/energy falls into it and is compressed smaller and smaller to an infinitely small point. Nothing comes out of a black hole by any process.

Scientists speculate that ultimately, all the matter/energy in the cosmos will fall into one supermassive black hole and be destroyed. That reminds us of the words of Peter in 2 Peter 3:10-12, “The elements will be dissolved.” There was a beginning, and it was caused by God, an entity outside of space/time, and there will be an end.

Endothermic or Ectothermic – What’s the Difference?

You are an endothermic mammal. That means your body’s metabolic rate controls your internal body temperature. We describe that condition by saying you are “warm-blooded.” Many life forms on our planet are “cold-blooded” (ectothermic) because the environment controls their internal body temperature. The limitation of being cold-blooded is that it requires warm environmental temperatures. Ectothermic life forms can’t survive in polar areas. Endothermic life can survive almost anywhere.

During the time of the dinosaurs, the planet was very hot. That means biological systems, including plants, grew quickly. Those conditions were part of God’s preparation of resources that humans would need, including oil, coal, topsoil, and oxygen. However, the geologic record shows a point in Earth’s history when the climate radically changed.

As the entire planet cooled, areas at or near the poles became too cold for cold-blooded life to exist. Studies of bone growth rates and oxygen isotopes in ancient bones indicate a rapid change. This change would not be a problem for warm-blooded animals but would reduce the number, size, and activity of cold-blooded life forms.

The challenge would be to design living creatures that can translate food into enough internal heat to survive in a cold environment. Science News reported on studies of the inner ears of reptiles and mammals. In warm-blooded animals, the inner ear fluid is less viscous, requiring that the ear canals become smaller. As a result, fossils show a sharp change in inner ear morphology at the time when Earth’s climate became colder.

Many other changes were required for life to go from ectothermic to endothermic. However, the inner ear structure is preserved in the fossils, making it useful for scientists to study the history of life on Earth. The complexity of endothermy reminds us again of the words of Psalms 139:14, “I will praise you, for I am fearfully and wonderfully made: marvelous are your works.” In our time of changing climate, the design of life continues to show the wisdom involved in life’s creation.

The Cost of Raising a Child

The Brookings Institute writing in the Wall Street Journal reports that the average cost of raising a child from birth to age 17 has risen 9% over two years ago. The cost of raising a child is now $310,605 to feed, house, and provide primary care after birth. When you add to that the birthing cost, it becomes apparent that it is out of reach for many young couples and especially for young unmarried women.

In our materialistic and selfish society, many people are unwilling to sacrifice to spend that kind of money. That means they will push for an abortion, or they will neglect the child’s basic needs if the baby is born. Even worse, some parents pay the $18,271 a year cost of raising a child but resent it and let the child know they resent it. In my 41 years of public school teaching in South Bend, Indiana, I saw the consequences of kids facing physical, mental, and spiritual neglect.

Like many things wrong with society today, the problem is with the religious convictions of many adults. What is the result if you are convinced that humans are the product of blind mechanistic chance and don’t view a child as a unique creation of God with value and importance? You will not devote the resources or energy to ensuring your child is fully equipped to deal with life’s challenges.

The biblical plan for raising children is time-tested and proven to work. Ephesians 6:4 and Colossians 3:21 warn fathers, “…provoke not your children to wrath; but bring them up in the nurture and admonition of the Lord.” God’s plan calls for protecting children as a product of love. The cost of raising a child is more than money. A child must be treasured and nurtured not only in secular matters but in the knowledge of their value and spiritual nature.

Kids are searching for adults who will value them as they are. Unfortunately, the gender changing and promiscuity of our young people today are a product of the failure of adults to be willing to pay the cost of raising a child, including financially, emotionally, and spiritually.

Mauna Kea Wekiu Bug

We have frequently pointed out the importance of recycling agents in the natural world. They are creatures that take waste material of any kind and process it so that our planet is not inundated with excrement and dead bodies. The microbes that process dead material and produce soil, the dung beetles that handle excrement, and the vultures that eat carrion are among those recyclers essential to our environment. From the Hawaiian Volcano Observatory comes a recent discovery of another recycling agent to handle waste most of us would not even know existed. It’s the Mauna Kea wekiu bug (Nysius wekiuicola).

In 1980, scientists on Mauna Kea in Hawaii discovered the wekiu bug that handles natural waste on the summits of mountains where it is too cold for life to exist. At these extreme elevations, the jet stream, typhoons, and other sources of high elevation winds deposit the dead bodies of insects and birds. Instead of those bodies piling up, the Mauna Kea wekiu bug processes them. It’s a beetle whose name comes from the Hawaiian word for “summit.” This bug is specially designed to process mountaintop waste.

The wekiu bug has a straw-shaped mouth that it inserts into a dead insect or bird, allowing the bug to draw out any fluids or nutrients. That leaves the hard parts, which crumble and are carried away by rain, snow, ice, and wind. Even in this very inhospitable area for life, with frequent temperatures well below freezing and no surviving plant life, these bugs process organic material. The Mauna Kea wekiu bug is another example of God’s design to provide balance in nature. He created a natural system designed to allow the constant reprocessing of organic materials so that our planet can support an abundance of all kinds of life.

Natural Insect Control by an Insect

People struggle with many insects that give us diseases, impact our food supply, and even damage our clothing. Mosquitoes, locusts, grasshoppers, cockroaches, crickets, and the like have been a scourge prompting the use of pesticides. The pesticides, in turn, have brought cancer and attacks on our immune systems. Yet, we often overlook the fact that God has given us natural insect control by providing agents that eat insects, including birds, bats, fish, and even insects. One insect-eating insect that looks like it came from another planet is known to entomologists as “Mantis religiosa” but is commonly called the praying mantis.

The mantis has bulging eyes and a triangular-shaped head that swivels atop a long neck, giving it an odd extraterrestrial look. It is the only insect with three-dimensional vision. It holds its two front legs at an angle as if folded in prayer while actually poised to ambush prey. Those forelegs are armed with spikes so that when they capture an insect, it cannot escape.

Humans introduced the praying mantis from Europe into New York state in 1900 to control grasshopper infestations. Mantises are voracious eaters and can even be cannibalistic. Their population is partly controlled by eating each other when the food supply becomes reduced. Females sometimes eat the males and the egg capsules when there is a food shortage.

A mistake humans have made is using chemicals to control insect populations instead of using the natural controls God has given us. Spraying massive amounts of insect-killing chemicals kills everything, including insect-eating birds, fish, and insects like the praying mantis. We often hear people blaming God for the diseases and afflictions humans have caused.

The more we study the creation, the more we see natural insect control agents. They may require work and a more significant time investment than the easy process of spraying, but they cause far less collateral damage.

Neurotheology or Spiritual Neuroscience

Ancient societies considered epilepsy “the sacred disease” because they thought of epileptic seizures as religious experiences. In modern times some have argued that epileptic seizures stimulate a region of the brain’s temporal lobe that may explain the “religiosity” of some individuals. Neurotheology or spiritual neuroscience is a modern field of science that tries to understand religion by studying how the brain works.

In 2005 Dean Hamer published a book titled The God Gene, in which he claimed to have found a gene in Human DNA that would predict whether a person would believe in God. Experts criticized Hamer for his misuse of statistics and lack of understanding of genetics. James Clark wrote a book in 2019 titled God and the Brain (Eerdmans Publishing), in which he maintained that the brain has an area tied to religious experience. He called this the “agency detecting device” and asserted that the Creator put it there to cause us to look beyond the mechanics of science and seek the Agent behind creation. Dr. Malcolm Jeeves heads the Psychology and Neuroscience Department of the University of St. Andrews. He encourages a healthy discussion between religion and science while suggesting that there are realms beyond the reach of science.

Neurotheology or spiritual neuroscience is a very “soft science.” That means no scientist has conducted an experiment that answers the question of why some people are more religious than others. It would seem that attempting to find a cause for religiosity is futile because of the nature of our creation in the image of God. One theme throughout the Bible is that people must voluntarily choose whether to embrace faith in God. That belief can be affected by experience and evidence, but it is still up to each person to accept or reject God.

Atheists would like to find a physical cause for faith. If they could, they would deny the human spiritual nature and write it off as a mutation in our distant ancestors that we should eliminate. Agnostic Stephen Jay Gould maintained that science and religion were “non-overlapping magisteria,” meaning they each represent entirely different areas of inquiry. Perhaps that should apply to neurotheology or spiritual neuroscience.

In the August issue of the Journal of the American Scientific Affiliation, Toby Engelking wrote, “No matter how much we describe the way that minds work, we cannot say much about the way that they ought to work or why they are working at all. These are realms of philosophy and theology, realms which science is not equipped to venture into.”

David and Goliath – Fact or Myth

Skeptics frequently take a historical biblical story and attempt to show that it is impossible. Some religious folks have answered these challenges by saying the event is a miracle of God and thus is not open for discussion. The Bible certainly describes miracles of God that can’t be explained by natural causes and are therefore not available for investigation. For example, we can’t prove that Jesus raised Lazarus from the dead by scientific evidence because we were not there and can’t go back in time. If a person doesn’t believe in God, then a biblical record will certainly not convince them and may encourage them to reject the Bible as a bunch of fairy tales. In the case of David and Goliath, however, the evidence is strong that the account is credible.

Several years ago, I had an American Field Service student from South America in my physics class at Riley High School. When our class was studying centrifugal force and circular motion, he offered to show us what he called a “shepherd sling.” This was a pouch with a long cord attached at each end made from some non-stretchable material. One of the cords had a loop at the end of it, and the other cord was straight.

My student put a golf ball in the pouch and swirled the pouch and ball around his head, holding the two cords in his hand, the one with the loop wrapped around his finger. He got the ball/pouch going at a very high speed and then released the straight end of the cord, sending the golf ball flying at an incredible speed. Taking this outside, he could knock a tin can off a post at 100 feet. The force of the strike was so strong that the can flew a considerable distance. From 100 feet, this student could put a rock through a thick board.

Biblical Archaeology Review published an article examining the statistics for the encounter of David and Goliath. Archaeologists have discovered reliefs in the mortuary temple of Ramesses III showing Egyptian slingers defending a ship. An Assyrian relief from Nineveh celebrating Sennacherib’s military victories shows Assyrian slingers in 701 B.C. whirling stones toward Judahite defenders atop the walls at Lachish. Archaeologists have found the remains of slings and the stones used in them.

These ancient slings had military uses up to 400 yards, and Roman slingers used them at distances of 200 yards. Arabian slingers hunt game at 30 to 50 yards today, and a moderately skilled slinger can achieve up to 113 miles per hour. Goliath had a javelin that he could throw 20 to 30 yards, meaning that David’s sling was vastly superior with about twice the range.

God certainly facilitated the actions of David, but the story of David and Goliath has historical validity, indicating that it was not miraculous and not a myth.
