Harmony of the Gospels

When I was a seminary student in a gospels class taught by scholar R. C. Foster, the students received the challenge of assembling “a harmony of the gospels.” It turned out to be more of a chore than I expected. It was in the 1960s before the time of computers and word processors, which today allow you to rearrange text by electronically “cutting” and “pasting.” We had to literally cut and paste with scissors and glue. We had to take inexpensive paperback Bibles and snip passages from each of the gospels, assembling them into columns in a notebook, creating a timeline of Christ’s ministry. It was my first and only experience with cutting up Bibles.

When only one of the gospels told of a parable, miracle, or teaching of Jesus, the job was relatively easy. When more than one gospel writer told about the same incident, it required juxtaposing the two or more accounts. It was an excellent way to realize that witnesses often describe scenes differently. For example, Matthew, Mark, and Luke all tell of an incident that happened after Jesus and his disciples crossed the Sea of Galilee and arrived at a Gentile area known as the Decapolis. Matthew tells of two wild, demon-possessed men who lived in the tombs near the shore. These men, who terrorized the locals, came out of the tombs to challenge Jesus. Christ cast the demons out of the men and into a herd of swine. (See Matthew 8:28-34.)

Critics point out that when Mark and Luke tell the story, they speak of only one man. They claim this is an error in the gospels, and the descriptions can’t both be accurate. However, the critics miss the point. Matthew gives us the detail that there were two men, but Mark and Luke concentrate on the one who was the dominating personality, and they give more information on his actions. They tell us that chains couldn’t bind him, and nobody could tame him. He was naked and crying and cutting himself night and day. When he saw Jesus, he took a worshipful pose and called him “the Son of the most high God.” After Jesus cast the demons out of the man, people were amazed that he was sitting and clothed and in his right mind.

The people were then terrified not of the man but of Jesus, and they asked Him to leave their area. As Jesus prepared to get back on the boat, the formerly possessed man begged to go with Him. Jesus didn’t allow the man to go with Him but told him to go back and tell his friends, “what great things the Lord has done for you, and how He had compassion on you.” The man became a witness for Jesus in the pagan area of Decapolis. (See Mark 5:1-20 and Luke 8:26-39.)

When you read this account from all three gospel writers, you will find details the others omitted. A testimony to the Bible’s divine nature is not only the harmony of the gospels but also their brevity. Only the essentials are there. Matthew chose to reveal that there were two men, but he left out other details. Mark and Luke give more information about the one man Jesus appointed to be a witness for God in a pagan area.

The formerly pagan and demon-possessed man apparently was an effective witness to his neighbors. Months later, Jesus returned to the Decapolis and was met by “great multitudes” eager to see the one who had healed and restored sanity to the man of the tombs. Now the “Son of the most high God” was able to show compassion for multitudes of people. He healed “the lame, blind, mute, maimed, and many others.” (See Matthew 15:29-31.)

As a result of Jesus’ compassion and a restored man willing to share his story with others, many people in a pagan region “glorified the God of Israel.” And as a result of having to prepare a harmony of the gospels to pass R. C. Foster’s class, I came to understand and appreciate why the Bible contains four accounts of Jesus’ ministry.

A Poem Lovely as a Tree

In 1913 poet and journalist Joyce Kilmer wrote his best-known poem simply titled “Trees.” It begins with, “I think that I shall never see, A poem lovely as a tree.” In fact, poems and trees have one thing in common. They are hard to define. What one person considers poetry could be something very different to another. The same is true of a tree. How can we define a tree?

There is no universally accepted common or scientific definition of a tree. Scientists classify all plants and animals into categories such as family, genus, and species. But trees, in general, don’t fit into any of those categories. You can assign any of those labels to a specific tree, but you can’t fit all trees into one specific classification. The best you can do is say that all trees are in the plant kingdom.

Even the common concept of a tree is a bit vague. You could say that a tree is a tall, woody plant with branches, leaves, bark, and a trunk that shows rings when you cut it down. That means what we call “palm trees” are not trees. Neither are banana trees, papaya trees, or Joshua trees. Also, bamboo is a plant that can grow to heights that exceed many trees, but we classify bamboo as grass. Many woody plants that we call shrubs or bushes can grow as tall as a height. How tall does a bush have to grow before we call it a tree?

No matter how you define trees, consider the benefits they give us. From trees, we get wood for furniture, homes, and buildings. We get fuel for campfires and even heating homes. Without the wood from trees, our ancestors could not have built boats and wagons that allowed them to travel, explore, and spread around the world. Trees provide shade, protection from wind, and in many cases, fruit. They can live for decades, centuries, or even thousands of years, releasing oxygen and taking in carbon dioxide to reduce Earth’s greenhouse effect. We will never find a poem lovely as a tree in spring, summer, or fall.

In Genesis, we read about the progressive steps of creation as God placed on Earth first grasses, then plants bearing seeds, and then trees bearing fruit that was good to eat (Genesis 1:11-12). God told the first couple to enjoy the fruit of all the trees except one. The beauty of the paradise where God placed Adam and Eve must have been beyond description. However, the tragedy that came because of the sin of pride and disobedience did not completely destroy that beauty. A glimpse of it has remained for us to enjoy, and it inspired Joyce Kilmer to write those words, “I think that I shall never see, A poem lovely as a tree.”

No matter how you define trees, we could not live without them. Kilmer’s poem ends with, “Poems are made by fools like me, But only God can make a tree.” God made the trees, and it was on a tree that He made the ultimate sacrifice for the sin that began with Adam and Eve. (See I Peter 2:21-24.) Sin has marred the beauty of the world and our lives as well. However, God has provided the solution–if we are willing to accept it.

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).

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.)

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.)

Medical Challenges of Space Travel

Space exploration presents many challenges, but the medical challenges of space travel may dwarf the technical challenges. Spending lengthy sojourns on the International Space Station (ISS) has already shown some of the problems that future space travelers will face.

One problem astronauts face is space anemia caused by a lack of red blood cells. On Earth, the human body makes two million red blood cells every second to replace the ones that are lost. In space, the astronauts’ bodies lose three million red blood cells each second, and they must replace those cells. Anemia results from a shortage of the red blood cells needed to carry oxygen to all parts of the body. It causes fatigue, dizziness, and weakness.

Space anemia was well-known, but scientists thought the body would adapt and correct the problem after an extended time in space. Unfortunately, a recent study of 13 astronauts has shown that it is not corrected after six months on the ISS. Furthermore, it took three to four months to restore a near-normal red blood count after the astronauts returned to Earth. There was still a thirty percent greater loss of red blood cells even after that.

A new study on cosmonauts in the ISS shows another area of concern. Scientists studied the brains of twelve cosmonauts just before and after their space flights and again seven months after they returned to Earth. They used computer reconstruction of data from magnetic resonance imaging (MRI) to study the structure (gray matter) and connectivity (white matter) in the brain. The research showed shape changes in the brain, especially in the corpus callosum, a large bundle of nerve fibers that connect the brain’s two hemispheres. In addition, researchers detected “changes in the neural connections between several motor areas of the brain.” But, perhaps, the most concerning is that in the brain scans taken seven months after the cosmonauts returned to Earth, the changes to the brain were still present.

A journey to Mars and back will take more than twenty months. During that space flight, astronauts will need protection from radiation, food for proper nourishment, and to replenish red blood cells while they experience “rewiring” of their brains. The many medical challenges of space travel remind us how blessed we are that God has given us the perfect planet to call home.

Newly Discovered Human Body Parts

It would be an understatement to say that medical science has learned many things about the human body. But, at the same time, it would be correct to say that we have much more to learn. Recently, scientists have reported two newly discovered human body parts.

One of the recent discoveries is located inside the passageways of the lungs and plays a vital role in the proper functioning of the respiratory system. Researchers found some unique cells they named respiratory airway secretory cells (RAS). They discovered the RAS cells in the lung’s delicate, branching passageways known as bronchioles. Tiny air sacs called alveoli located at the tips of the bronchioles remove carbon dioxide and replace it with oxygen in the blood vessels. The RAS cells are designed to transform into new alveoli cells to replace ones that become damaged. When pollution causes damage, the RAS cells stand ready to come to the rescue. But, of course, humans sometimes abuse their lungs by smoking or vaping, which can cause more damage than the RAS cells can correct.

The other recently discovered body part is critical for chewing our food. The masseter muscle raises the lower jaw as we chew. Medical scientists knew that there were two muscle layers inside the masseter. However, researchers have found a third muscle layer deep inside the masseter. They said that the newly discovered layer helps stabilize the lower jaw and is the only part of the masseter that can pull the jawbone backward. The researchers propose to name this muscle layer the “Musculus masseter pars coronidea.” Perhaps we can abbreviate that to MMPC.

When science assumed that anatomical research had discovered every part of the human body, they found something new. Both of these discoveries can benefit medical treatments. The RAS cells may lead to new therapies for lung damage. Knowing the existence of the MMPC may help doctors when performing surgery on the jaw region. Finding these newly discovered human body parts indicates that we still have more to learn about our “fearfully and wonderfully made” bodies (Psalms 139:14).

One Daily Drink Can Shrink Your Brain

A new study in the U.K. shows that even light alcohol consumption harms the human brain. The study involved more than 36,000 participants between 40 and 69. The conclusion was that as little as one daily drink can shrink your brain.

Many studies have shown that drinking alcohol has long-term effects on cardiovascular and brain function. Chronic excessive alcohol consumption contributes to health problems such as cardiovascular disease, cancer, accelerated aging, and malnutrition. However, some earlier studies suggested that limited alcohol consumption might benefit your health. The researchers involved in this study wanted to determine the effect of small to moderate alcohol consumption. The results were surprising.

The 36,678 participants reported their alcohol consumption, and the researchers performed an MRI scan on their brains. Researchers grouped the subjects by average daily intake of one, two, or three or more alcohol units–or none. A unit was about eight ounces of beer or three ounces of wine. The researchers adjusted for age, genetic ancestry, and sex.

Those who consumed even one alcohol unit per day showed noticeable differences in the brain structure, especially in the brain stem, putamen, and amygdala. Those areas regulate heart rate, breathing, learning, motor control, and processing of emotions. The regions of white and gray matter in the brain shrank exponentially with increased alcohol consumption. The brain’s gray matter is that area that processes information, and the white matter enables communication between gray matter regions. One daily drink can shrink your brain, leading to decreased cognitive ability.

The more units of alcohol consumed, the more significant were the differences compared to those who drank no alcohol. For example, for people who reported drinking three alcoholic units per day, their brains appeared to be 3.5 years older than those who drank none. For those who drank four units, their brains aged by ten years.

Interestingly, the U.S. National Institute on Alcohol Abuse and Alcoholism recommends that men limit their consumption to two drinks per day. This study shows that one daily drink can shrink your brain. So the bottom line is that if you want your brain to stay young longer, avoid drinking alcohol altogether.

Methane and Life on Other Planets

Astronomers are constantly looking for signs of life on other planets or moons. One of the potential clues they seek is methane, a hydrocarbon gas consisting of one carbon atom and four hydrogen atoms. It is classified as a “greenhouse gas” because it can trap heat on Earth’s surface resulting in “global warming.” It’s a more effective greenhouse gas than the much-discussed carbon dioxide. Methane is produced by organic decomposition and in the digestion process of ruminants such as cows and other animals. Scientists seek to learn more about a possible connection between methane and life on other planets.

Since living things create methane, scientists regard it as a potential “biosignature” indicating life on an astronomical body. For that reason, astronomers are searching for methane on planetary bodies. News reports have sometimes gone overboard with stories about methane and life on other planets. However, not all methane is created biologically. Volcanic eruptions can release methane gas, and even asteroid impacts can add methane to a planet’s atmosphere. So how can scientists tell if the methane is a sign of life on a body far out in space?

For one thing, gasses from a volcano would contain not only methane but also carbon monoxide. The biological creation of methane would consume carbon monoxide. When examining the gasses in a planet’s atmosphere, a large amount of BOTH methane and carbon monoxide would probably indicate that the methane was not a biosignature. Methane alone would be a more likely indicator of the possibility of life.

However, an abundance of methane without carbon monoxide would not prove the existence of life on a planet. As we have said before, many factors are required to make a planet suitable for any kind of life, especially advanced life. NASA’s James Webb telescope, launched in December, is still working to reach full functionality. When it does, a significant part of its purpose will be to look for methane in the atmosphere of exoplanets.

When results indicate that the Webb telescope has detected methane on a planet, news reporters may sensationalize the facts to suggest more than they deserve. Reputable scientists are more cautious in their predictions about methane and life on other planets. Nevertheless, we are excited about the possibility of learning more about the universe with the new Webb space telescope.

As we have said before, the Bible doesn’t tell us if there is life on any other object in space. If there is, we believe that God put it there. We are not afraid of scientific investigation because the more we learn about the creation, the more we stand in awe of the Creator.

Return of the Lyrid Meteor Shower

In late April each year, we see the return of the Lyrid meteor shower. It may not be the most spectacular meteor shower of the year, but I find it easier to observe. That’s because, in our part of the world, it comes at a time when the weather is mild enough to sit outside and watch (unlike the Geminids in December) and before mosquitoes become a problem (as with the August Perseids shown in the picture).

This year, the return of the Lyrid meteor shower is from April 14-30, with the peak on the night of April 22. Typically, the Lyrids display five to 20 meteors per hour at the peak, although, in some years, the number has been higher. Written records of the Lyrid meteor shower go back 2700 years when Chinese astronomers made note of it in 687 B.C. A Korean account from A.D.1136 says that “many stars flew from the northeast.”

If you see the Lyrid meteor shower, you will not be looking at falling stars, although you may get that impression. Instead, you will see tiny fragments of Comet Thatcher (officially C/1861 G1), discovered in 1861 by amateur astronomer A.E. Thatcher. That year was the last time the comet flew by our planet at 31.1 million miles (50.1 million km). Its next return to our vicinity will be sometime around the year 2280. Meanwhile, Earth’s orbit around the Sun causes us to pass through debris the comet left behind. So we see those fragments as they burn up from the effect of atmospheric friction.

We live in an orderly universe on a planet positioned to allow observation and study of the cosmos. Our planet is designed with an atmosphere and magnetic field to protect us from comet debris, meteorites, cosmic rays, and solar wind. If you have the opportunity to observe the return of the Lyrid meteor shower, use it as a time to thank the Creator for allowing us to live in the just-right time on a just-right planet in a just-right location in the universe.
