Interpret the Bible Literally

We hear from both skeptics and biblical fundamentalists about taking the Bible literally. However, even those who claim to interpret the Bible literally often don’t, resulting in some ridiculous errors. Furthermore, those misinterpretations cause faith challenges for better educated young people because they realize that some things people ascribe to the Bible are not logically or scientifically possible.

To interpret the Bible literally, you must take the whole Bible and not cherry-pick individual passages to support what you already believe. It also means looking at the original language and asking how those to whom it was written would have understood it. Let’s take a modern example. What does the Spanish phrase “Juan tiene frio” mean? Translated literally, the words would mean “John has cold.” It could either mean John is cold or John has a cold – he is sick. How would you know what the writer intended?

Sometimes the wording looks like it is unrelated to what it actually means. For example, what does “Juan me cae bien gordo” mean? The words are “John me falls well fat.” So is this a comment about my waistline? My Spanish-speaking associates tell me it means “John really bugs me.” You would know that by understanding the culture and how those who speak the language would understand it.

This is also true of Hebrew and Greek. When the first chapter of Genesis lists the animals God created, the Hebrew words refer to creatures the readers knew. “Behemah” in verses 24 and 25 did not include dinosaurs, platypuses, giraffes, or elephants. People would have understood it to refer to the cattle the readers knew. “Remes” in the same verses would not have meant snakes and komodo dragons but rather the smaller examples of livestock like goats and sheep the readers knew. In Genesis 9:1-3, “remes” is included as an animal that God said would be food for the Israelites. We know that the Jews had food restrictions that would not have included snakes, worms, and komodos, so the meaning of “remes” is clear.

Those who attempt to include dinosaurs on Noah’s ark are not taking the Bible literally. When they do that, they provide fuel for those who say the Bible is a book of myths. We must understand what it means to interpret the Bible literally. We will deal with more on the dinosaurs tomorrow.

Carrion Beetles – Carcass Recyclers

American burying beetles (Nicrophorus americanus) are among nature’s most efficient and fascinating carcass recyclers. These largest carrion beetles in North America can be up to 1.77 inches (45 mm) long. Unfortunately, they are “critically threatened.”

American burying beetles have a unique appearance, with two bright orange patches on the covers of each of their shiny black wings. Their pronotum, a shield-like area just behind the head covering the thorax, also has an orange patch. In addition, an orange patch between their eyes is rounded on males but smaller and more triangular on females.

Carrion beetles such as American burying beetles play a vital role in returning valuable nutrients to the soil. Dead things would accumulate if tiny insects and microorganisms didn’t do that job. These carcass recyclers fly at night and use chemical receptors on their antennae to detect dead or decaying flesh.

It is unusual in the insect world for both the males and females to participate in raising the young, but American carrion beetles are involved parents. The male will find a carcass about the size of a small bird or chipmunk and attract a female. The two beetles bury the carcass, and the female will lay up to 30 eggs. When the larvae hatch, both parents feed the young from the decaying carcass while keeping them safe underground. After about a week, the larvae go into a pupal stage and eventually emerge as adults that live for about 12 months. When the temperature drops, they bury themselves for the winter and re-emerge in the spring.

We seldom think about the importance of carrion beetles as carcass recyclers, but they play an essential ecological role. Each living species is designed to serve a function in nature, and every loss destabilizes the fragile balance God gave us to enjoy and protect. We can know there is a God by the things He has made (Romans 1:20).

Disease Spillback from Humans to Animals

Many times animals pass diseases on to humans. However, recent research by scientists at Georgetown University shows disease spillback from humans to animals. In nearly 100 documented cases, humans have given wild animals a disease.

This discovery has implications for the spread of SARS-CoV-2, the virus that causes COVID-19. This virus has shown up in wild white-tailed deer populations in the United States and Canada. Medical researchers are concerned that the virus may mutate in these animal populations providing a reservoir of variants that can spread back to humans.

In addition to the deer, researchers have found the SARS-CoV-2 virus in mink farms, lions and tigers in zoos, and various primates. The “cute” animals seem to be the primary source of viruses because of their proximity to humans. Taking care of the creation involves allowing wild animals to be wild. When animals are domesticated, they can bring their pathogens with them into human homes.

We cannot blame God when a disease occurs in humans that was contracted by improper management of the animals that live around us. The exotic animal business has brought with it some extreme risks to humans. Not only can animals pass diseases to us, but disease spillback from humans to animals is possible and dangerous.

As our knowledge of disease and genetics increases, we learn to prevent ailments in the human population. Understanding the uniqueness of the human genome has become increasingly important in the medical field. Limiting contact with wild animals may help to avoid possible future pandemics.

Pyramid Power Mystery

I have many interesting stories from my years as a public school science teacher. One of my favorites involves a pyramid power mystery. A student in my physics class maintained that the Great Pyramid in Egypt was a creation of aliens who used methods unknown to modern science. He claimed that the pyramid had mystic forces that could benefit humans if we only understood it.

This young man claimed that one property of the Great Pyramid was that anything contained within it would not deteriorate. He had a “Great Pyramid” model that he said he could use to prove it. I had some apples in my classroom refrigerator, so I offered him a challenge. He would put one apple in his “Great Pyramid” model, and I would keep mine in the fridge. Then, in 14 days, we would both eat our apples in front of the class. He agreed, and the contest was on.

My classroom had windows on the east side of the building and no air conditioning. Not only was the classroom frequently hot, but sunlight bathed the room because there were no window shades. Every day, I would bring my apple out of the refrigerator, and the kids would join me in challenging the Great Pyramid promoter. About a week into the contest, the pyramid apple changed color, and dark spots appeared. Some fluid seeped onto the floor of the “Great Pyramid,” and the kids in the class started kidding my challenger about how bad that apple was going to taste. After the weekend, I came into my classroom, and the “Great Pyramid” was gone, and the apple that was in it had also disappeared. You could call this a pyramid power mystery because the pyramid and the apple were nowhere to be seen.

That was only a minor case of pyramid power mystery claims. For example, over the years, authors have written books and articles making unsupported alien claims about the construction of the Great Pyramid of Giza. In truth, it is an amazing demonstration of human engineering talent and shows that ancient people knew how to build structures on a colossal scale. According to World Archaeology magazine, discoveries in the last ten years leave no doubt that the Great Pyramid was not an alien creation. It was the product of humans who understood how to make massive structures. We see a connection to the biblical account of the Tower of Babel in Genesis 11.

In 2013, researchers found fragments of papyri documents near the Red Sea containing logbooks and records. The documents detailed the activities of teams building the Great Pyramid, known to the locals as Akhet Khufu for the 4th Dynasty king who reigned from 2633 BC to 2605 BC. Dubbed “The Red Sea Scrolls,” they show the planning and construction logistics, from mining copper to make tools to cutting the stones to the housing arrangements for the workers.

Humans often attempt to extend their physical lives in costly ways, and the pyramids of Giza are a classic example. Unfortunately, the reality is that this physical body will return to the dust from which it came, and nothing humans can do can change that. However, we can preserve the real “us,” our spiritual bodies, for eternity. In 1 Corinthians 15:51-57, Paul describes “a mystery,” which is the resurrection to incorruptible spiritual bodies. The pyramid power mystery is no longer, but the promise that God will preserve our soul for eternity will remain a mystery to those of us who are disciples of Jesus Christ until that great day of the resurrection.

Alcohol Is a More Destructive Drug

The media and medical profession pay a great deal of attention to the damaging effects of methamphetamine, cocaine, and opioids, but alcohol is a more destructive drug. In 2019, alcohol directly caused the deaths of almost 79,000 people in the United States from illnesses and car crashes. In 2020, the first full year of the COVID pandemic, more than 99,000 people under age 65 died directly from the use of alcohol. That was a 25.5% increase and more lives than COVID claimed that year for those under 65.

There is a widespread belief among many college students that you can’t have fun unless you drink. At the University of Notre Dame, Ted Mandell teaches a class called “Drunk on Film.” The subtitle of the course is “The Psychology of Storytelling with Alcohol and Its Effects on Alcohol Consumption.” Using film clips from movies and alcohol commercials, he helps students understand the problems with drinking and how advertisers and filmmakers seduce them into thinking that excessive alcohol consumption is normal and desirable.

One film that Mandell uses is a 20-minute clip from a documentary by Sut Jhally titled “Advertising at the Edge of Apocalypse.” It shows how alcohol advertising weds drinking to the sports industry and portrays alcohol as an alluring lifestyle. You would think that bright college students could see the indoctrination by the alcohol industry and its role in destructive sex and health issues. However, that is simply not the case. Stress is a part of the problem students face, but peer pressure is a more powerful motivator to drink.

From a Christian perspective, if you believe that your body is the temple of the Holy Spirit (1 Corinthians 3:16) and should be cared for both physically and mentally, that should lead you to avoid alcohol. Seeing the results for people who drink alcohol and use other recreational drugs should be a motivator to avoid them. Our culture condemns the use of meth and crack but sanctions the use of alcohol and marijuana. Looking at the evidence should convince thinking people that alcohol is a more destructive drug.

Why Does the Moon Look Larger Near the Horizon?

Perhaps you saw the total lunar eclipse last night, or maybe it was only umbral (partial) in your area. Either way, it reminds us of God’s intricate design that allows advanced life on this planet. As you watched the Moon, you may have seen it close to the horizon or high in the sky. Why does the Moon look larger near the horizon? Is it really larger, or are your senses being fooled?

Here is a simple experiment you can do with a camera or smartphone. Take a picture of the Moon when it rises and then take another picture of it high in the sky on the same night. Now compare the Moon’s size in the two pictures. You will see that the Moon is the same size. Better yet, stretch out your arm and compare the Moon’s size to your thumb at the two positions on the same night.

If you are thinking that the Moon looks larger at the horizon because it is farther away at that time, that is clearly not the case. The Moon’s distance, and therefore apparent size, does vary somewhat throughout the year, but not on the same night. The difference in apparent size when the Moon is closest to Earth and farthest away is only about 7%. The human eye can barely detect that difference.

So why does the Moon look larger near the horizon? First, realize that it is not our eyes but the human brain that does the seeing. When the Moon is near the horizon, we compare it to distant trees and buildings that we know are large, so we think the Moon looks larger. However, when it is in the middle of the vast, open sky, the Moon seems small by comparison.

We interpret what we see based on previous experiences and prejudices. That means our brain interprets new information filtered through those prejudices. That brings up another question. How does the human mind interpret other areas of understanding, such as the existence of God? Are there filters in your line of sight that can block you from seeing the truth?

The First Lunar Eclipse Visible In North America In 2022

The Only Lunar Eclipse Visible In North America In 2022 — A Total Lunar Eclipse or “Blood Moon”

This Sunday night, May 15-16, 2022, a total lunar eclipse will be visible in the Western Hemisphere. It will be the first lunar eclipse visible in North America in 2022. The totality will be visible in the eastern United States and Canada and all of Central and South America. It will also be visible in Antarctica, but most of the population seeing it there will be penguins. The partial, or penumbral, eclipse will be visible in the western U.S. and Canada as well as Africa, Europe, and other areas. To find out exactly if or when you can see it in your area, go to TimeandDate.com.

Lunar eclipses occur at the time of the full moon. People commonly call May’s full moon the Flower Moon since it’s the time of year when many flowers are blooming in the Northern Hemisphere. Full moons occur approximately once per month when Earth is between the Moon and the Sun. A couple of times per year, the alignment is so precise that the Moon falls within Earth’s shadow, creating an eclipse. That will happen only one more time this year, on November 8, which also happens to be election day in the United States. However, the November eclipse of the Moon is no omen for the elections.

A total lunar eclipse, often called a “blood moon” because of its color, is not an omen of anything, despite what some false prophets may suggest. It is a natural function of the solar system God created for us. We can know precisely when eclipses of the Sun and Moon will occur because our solar system is not chaotic. Our Creator gave us an orderly, life-sustaining system in which to live and carry out His plan. With that in mind, enjoy the first lunar eclipse visible in North America in 2022. Let it be a reminder of God’s creative wisdom and His love. (See Genesis 1:16 and Psalms 72:5-7.)

Animals Are Not Helpless Creatures

Sometimes people suggest that animals are at the mercy of the elements and therefore plagued with disease, pain, and suffering. The fact is that animals are not helpless creatures suffering from massive illnesses and infections that make their lives a painful misery. Instead, the Creator has given animals immune systems to resist disease and an awareness of ways to treat injuries.

By watching animals, humans have learned that certain plants can fight infections and help to heal wounds. For example, we use aloe to relieve sunburn pain, but animals have been using it for various skin conditions for many years. Various plants bring comfort to animals when they are sick or injured, and humans have copied plant use by animals for treating a variety of ailments.

Researchers recently discovered that not only can plants offer relief to animals, but insects are also medically beneficial. More surprising is that animals know about these remedies and can use them. For example, scientists have observed chimpanzees catching a tiny flying insect and placing it on a wound or sore to provide relief. Researchers have not yet identified that insect, but they have seen primates use other arthropods and certain leaves to help heal wounds and provide relief from pain.

When humans don’t upset the system, animals are not helpless creatures. They have a minimum of suffering, and they even know ways to treat wounds and infections. Death in the undisturbed animal world is rapid and purposeful. Human interference with the natural balance often results in prolonged suffering for animals.

Too often, we prolong the suffering of other humans with expensive treatments that don’t produce a quality of life. However, we have much to learn from the world God created, and perhaps a tiny flying insect can be one more aid to healing or pain relief if the researchers can just find out what it is.

The Unique Design of Our Solar System

We have pointed out that recent reports from NASA reveal that astronomers have found more than 5000 planets orbiting stars other than our Sun. These extra-solar planets show that our solar system is a rarity in space. The unique design of our solar system strongly supports the idea that it is a product of intelligent creation, not a cosmic accident.

One might suggest that having a life-bearing planet is like trying to shoot something. If you shoot enough times, you will eventually hit the target. So likewise, if we find enough planets outside of our solar system, we will ultimately find one like Earth that can support life and even beings like ourselves. However, recent discoveries show that our solar system is so unique that it cannot be a chance production.

One discovery from the observation of exoplanets is the uniqueness of having a rocky planet orbiting this far from a star. In a study of 169 detected and confirmed rocky planets orbiting nuclear burning stars, more than 90% of them orbit their stars ten times more closely than Earth orbits the Sun. Being closer to their stars would mean that the lighter elements in those planets would be burned away, so those planets should be denser than our rocky planets. However, the data shows the exoplanets have a density of 4.472 grams/cc, while Mercury, Venus, and Earth are 5.395 grams/cc. What does this fact suggest?

The starting point for interpreting this data is the Sun. It has a very unusual lack of refractory elements (those elements which boil easily). That is especially true of lithium which is 170 times lower in abundance in the Sun than in the rest of the solar system. Scientists have advanced various theories about why that is, but it means that the Sun’s flaring activity is at a very low level compared with similar stars. Thus the Sun has an exceptionally low level of harmful ultraviolet and X-ray radiation.

As we look at rocky extra-solar planets orbiting other stars, we see they are very close to their stars. Since the stars would burn off the light elements with low boiling temperatures, we would expect to see rocky material left behind. The fact that our Sun has rocky planets that are farther away is because of the Sun’s unusually low levels of refractory elements and low levels of ultraviolet and X-ray radiation.

Other factors about exoplanet systems demonstrate the unique design of our solar system. For example, Earth’s chemical composition is unique. The extra-solar planets scientists have studied do not have the chemicals needed in the amounts required for advanced life forms to exist. Also, our Moon plays an essential role in the system that allows Earth to retain its atmosphere and hydrosphere.

With more data from astronomers studying extra-solar planets, it becomes increasingly clear that our Sun and our solar system are not typical products of accidental chances in space. The number of parameters that our unique solar system possesses speak of design. The unique design of our solar system shows that God’s creative hand has done much more than we imagined. This shows the truth of the old cliche that “the more we know of the creation, the more we appreciate the role of the Creator.”

How Do Plants Communicate?

People communicate with each other through spoken and written words and actions. We also know that animals communicate by using sounds and movements. However, we may not be aware that plants talk to each other. They don’t do it by speech, writing, sounds, or movements. Since they are stationary and silent, how do plants communicate?

Plants are continuously engaging with other plants in their environment, mostly underground. For example, the roots of most plants host fungi, and working together, the plant roots and the fungi create underground structures called mycorrhizae. These mycorrhizae resemble a web system surrounding the plant’s roots, helping the plant absorb nutrients such as nitrogen and phosphorus in a symbiotic relationship. As the mycorrhizae help the roots absorb essential nutrients and water, the plant uses photosynthesis to produce sugars which it shares with the fungi.

But how do plants communicate? The mycorrhizae can connect multiple plants into a network through which they can share energy and information. This web creates a fine-tuned community-wide sharing system. Through this communication channel, plants can pass defensive chemicals to protect against insects. When pests such as aphids attack a plant, it can send a message to its neighbors so they can preemptively activate defense responses. In this way, mycorrhizae enable a system of cooperation between plants.

However, when resources such as light or nutrients are scarce, a plant can limit its mycorrhizae connections and avoid making new ones. Then when resources are good, they can restore their sharing network and even make new connections. When the plants connected in the mycorrhizae network are closely related, they share more than if their neighbors are not close relatives. Trees use these fungal networks to communicate and share but also sometimes to sabotage their rivals. Plants determine when to share and when to maintain their independence.

As we investigate the question, “How do plants communicate?” we realize that they behave as humans often do, putting their own interests first. Yet, sharing and working together is part of God’s design for life, and humans should always follow the example set by Jesus in His life and teaching. (See Matthew 5:38-48 and 25:31-46.)
