Who Is Jesus?

Christmas reminds us of the birth of Jesus, but why is the birth of a baby two millennia ago relevant today? The answer to that question depends on the answer to another question. Who is Jesus? People have various ideas of who Jesus is. Some say He is God. Others say He was just a man who was a good moral teacher. But, if Jesus is not God, He could not have been a good moral teacher. Let me explain why.

There is no doubt that Jesus was born a human being. The shepherds who saw Him in the stable and the people who watched Him grow up in His hometown of Nazareth could verify that. He grew to be a rabbi, a teacher, and He had many followers. His select group of disciples who talked with Him and ate with Him and lived with Him knew that He was a man. But His teaching was like no other man. He taught with the authority of God. He claimed to be God. He claimed to forgive sins, which only God can do.

Thus, if that baby born in Bethlehem were merely a human being who grew to be a man and said the things He said, He would not be a good moral teacher. He claimed to teach the truth, and He even claimed to be the truth. He claimed to be God! If He were not God, He would be a liar or a madman, but He would not a good moral teacher.

So who is Jesus? What do we celebrate at Christmas? We remember that God took on flesh as a baby who grew to be a man. He lived a sinless life because He is God. But He did not come merely to show us how to live a sinless life. He knew that we could not. He came to redeem us—to be a sacrifice for our sins.

When Jesus was on Earth, He was truly man and truly God. He could be the sacrifice for sins only because He was God. Although Jesus was sinless, He was not a third-party victim selected to bear our punishment. It would be immoral to punish an innocent man for the sins of all the guilty people. He was also the divine lawgiver and judge, so He could choose to suffer the penalty of His own law and bear the sins of all people. One man could only bear the punishment for His own sins. God can bear the punishment for all.

So who is Jesus? On that night near Bethlehem, the angel did not merely announce the birth of a baby boy. The angel said, “I proclaim to you good news of great joy that will be for all the people…a Savior was born for you, who is the Messiah, the Lord” (Luke 2:10-11 CSB). Have you allowed Him to be your Savior?

December Solstice and What It Means

After today, Sunday, December 22, 2019, the hours of daylight will begin to be longer in the Northern Hemisphere where we live. Last night at 11:19 p.m. local time (Eastern Standard), the December solstice occurred as the Sun reached its lowest point in the dome of the sky, even though we couldn’t see it. It happened at the same moment all over the Earth, but, of course, local times varied. (It was at 04:19 Universal Time, and you can figure your local time from that.)

The December solstice ushers in winter in the Northern Hemisphere and summer in the Southern Hemisphere. So for those of us in the north, the days will now start to slowly get longer as the weather gets colder. South of the equator, the situation is just the opposite. At the North Pole, there are 24 hours of darkness when the Sun never appears. At the South Pole, the Sun is up for 24 hours.

Although the December solstice is the time when the Sun is at its farthest point south, it hasn’t moved. We have. Earth’s axis is tilted 23.5 degrees from the path of its orbit path around the Sun. Each year that tilt causes us Earthlings to perceive that the Sun is moving north or south. Earth’s orbit is somewhat elliptical rather than a perfect circle. The point when Earth is closest to the Sun occurs in January during the Northern Hemisphere’s mid-winter. It’s mid-summer in the Southern Hemisphere, so you might think that their summers would be extra hot. Whatever increased heat would occur because of the proximity of the Sun is counteracted by the fact that the Southern Hemisphere is mostly covered by oceans which absorb the heat. That is just another part of our amazingly well-engineered planet.

In Genesis 1:14, we read that God said, “Let there be lights in the expanse of the sky to separate the day from the night, and let them serve as signs to mark seasons and days and years.” Ever since Adam and Eve, people have recognized the Sun’s regular path across the sky and the changes in daylight, sunrise, and sunset times throughout the year. In ancient times, they didn’t understand why. We know why and we marvel at the design.

Every creature on Earth is affected in some way by the length of daylight. Historically, people in the Northern Hemisphere have celebrated the December solstice because it means the days will start getting longer, and spring will return. In ancient Rome, the people called their celebration Saturnalia and honored their pagan god Saturn with immoral behavior. With the coming of Christianity, the Christians re-purposed the holiday to honor the coming of Christ into the world. While the pagans celebrated with debauchery, the Christians made it a time of praising God and the gift of His Son. Jesus was almost certainly not born at this time of year, but more likely in the spring. However, we should take time to honor God for the beautiful design of our planet that makes life possible, and the wonderful gift of Jesus that makes eternal life possible.

Evolution Experiments and their Results

What if we could speed up time to test the concept of evolution? A scientist can’t wait millions or billions of years to study the process of natural selection as it creates new creatures. With that in mind, science must devise evolution experiments to study many generations in a much shorter time.

More than thirty years ago, Richard Lenski, who teaches at Michigan State University, began a project to study the evolution of the bacteria Escherichia coli, commonly known as E. coli. The project is called the Long-Term Evolution Experiment (LTEE). The scientist and his assistants carefully track the naturally-occurring random mutations in succeeding generations of E. coli. The environment for the bacteria is optimized for these one-cell creatures to grow and reproduce. Mutations are often harmful, but sometimes beneficial mutations lead to an improvement in the bacteria’s reproductive ability. Natural selection removes the bacteria with harmful mutations while those with beneficial mutations become more fit and reproduce. It’s what we call survival of the fittest.

Since 1988, the evolution experiment has continued, and scientists have kept careful records of the changes. Since the generation period of these bacteria is much shorter than that of humans, the study has gone through 70,000 generations. That is equivalent to more than 1.75 million years of human generations.

Through thousands of generations, there have been billions of mutations. Beneficial mutations that have lasted and accumulated amount to dozens. It is interesting that as time passes, successful mutations become increasingly rare. What the scientists are looking for is what they call “historical contingency,” which means a succession of small, almost inconsequential changes that accumulate to create significant changes.

So how has the E. coli changed after the 70,000 generations in this evolution experiment? The latest generation of E. coli can reproduce 70% faster than their ancestors. They are still bacteria. In fact, they are still E. coli bacteria. They have not mutated into some more advanced form of life. Dr. Lenski wants to see funding made available to continue the experiment for another 30 or even 300 years in the hope of seeing more dramatic results.

The LTEE has inspired other scientists to conduct evolution experiments. There is one at Harvard experimenting with yeast. Other scientists have experimented with fruit flies (Drosophila) to study the evolution of multi-cell creatures. They have bombarded the fruit flies with radiation and chemicals, changing light levels, and changing temperatures. After thousands of generations, the result has been mutant fruit flies with extra eyes or wings that didn’t function. They were still fruit flies.

The bottom line is that multi-generation evolution experiments have not resulted in new creatures or even greatly improved old creatures. The changes resulting from mutations and natural selection are either harmful or insignificant. God created animals to adapt and change due to environmental forces. Humans can change and sometimes improve animals by selective breeding. We see that very clearly in the many and very different breeds of dogs. But the evidence seems to indicate that only God can make a Canine or a Drosophila or an Escherichia—or a human.

You can read about the LTEE in the December 2019 issue of Discover magazine, page 49.

Humans and Music

I went with my grandson to a musical instrument mega-store, where he was looking for an amplifier for his bass guitar. In addition to being a guitarist, he is also a drummer. While there, my ears were accosted as he tested a drum set and then tried out several bass guitar amps. The bass was so loud it rattled objects in the vicinity, and I could feel it pounding on my body. The experience reminded me of the connections between humans and music of all kinds.

My grandson purchased nothing because he didn’t find anything he liked in his price range. As we left the store, I was a bit relieved since my ears were still ringing. Stepping out into the parking lot, the sound of heavy traffic on the busy New Jersey street was relatively quiet.

Humans and music have been connected from the beginning. The artifacts left behind by the earliest humans include primitive musical instruments. Music styles change, and tastes in music vary from person to person. Just think of all the different musical genres and styles that people create and enjoy from country to classical, from jazz to gospel.

Music can stir our emotions. It can transport us to new places in our minds or stimulate us to action. Music can soothe our troubled souls, or a sad song can make us cry. The words of Christian songs can inspire us, and music can also tempt us into sin. Music goes beyond our minds and reaches into our emotions. What is it about music that so moves us? Perhaps it’s a desire for heaven.

Read the book of Revelation, and you will get an idea of the role of music in heaven. Music and worship go together, both in this life and in the life ahead. One of the things that distinguishes humans is our ability to create, perform, and appreciate music. Since we are created in the image of God, that must mean that God appreciates music also. Revelation indicates that singing for God before His throne will be a joyful experience. Until then, humans and music will go together as we long for the time when we are at home with God. For now, singing as we worship Him in our assemblies brings us joy as we honor our Creator.

Wood – Natural Multipurpose Building Material

We have mentioned before that many human inventions are actually adaptations of things we see in nature. That applies to products from Velcro to high-strength materials to airplanes. However, there are times when we can’t improve on the natural product, so we use it as God created it. An example of that is wood. It’s a natural multipurpose building material. Wood is strong, durable, flexible, weather-resistant, lightweight, and non-toxic. Lumber from trees is the most common building material for homes and other housing structures.

How could there be such a well-designed and valuable natural multipurpose building material? Wood is produced in a living plant. Under the protective bark of a tree lies the cambium layer. It is the innermost layer of the bark where growth takes place. Each year, during the warm months, the cambium produces living cells, which become the new sheath expanding the trunk of the tree. The layers from previous years remain as the wooden skeleton giving strength to the tree. If you cut it down, you can count those layers as visible rings revealing the age of the tree.

The tree’s roots take in water with vital nutrients from the ground. Within the woody trunk, there are microscopic conduits called xylem carrying that water up to the leaves. Just outside of the cambium, another layer of micro-ducts called phloem moves sugar-water that the leaves produce using the amazingly complex system of photosynthesis. The phloem supplies nourishment that the cambium requires to build the new sheath of wood. When the growing season ends, the phloem carries the remaining nourishment to the roots for winter storage until next spring.

Trees often lose branches from wind, ice storms, other natural means, or by human intervention. When that happens, it can throw the tree off balance. The cambium steps in to build a thicker sheath on the side where the limb was lost, reinforcing the tree to bear the uneven load. When examining the rings of a felled tree, a ring that is thicker on one side indicates a fallen branch. The tree automatically takes care of the area of the lost limb by covering it with new annual sheaths.

Take a moment to look at the wood in your house. That natural multipurpose building material in the window and door trim, the floor, and your furniture was once alive. It was growing and transporting sap while the leaves converted sunlight and water into sugar-water to nourish the tree, and the cambium created new growth. The lines in that wood tell the story of days and years of rainfall, sunshine, wind, and changing temperatures in a forest somewhere in the world. The wood in your house is not there by accident, and we don’t believe the tree was a natural accident, but the work of a creative Engineer.

Trees Prepare for Winter

Imagine standing naked outside on a cold winter day. When winter’s chill comes, people take shelter. If we have to be out, we put on more clothing. Most animals have fur or feathers to help keep them warm, and they also seek shelter from the cold. Trees in winter can only stand there and take it for months at a time. So how do trees prepare for winter?

Living cells in plants or animals consist primarily of water inside a membrane. If you leave a bottle of water in your car on a night when the temperature drops below freezing, you know it will freeze and break the bottle. That is because water has the unique property of expanding as it freezes. The same thing can happen in living cells. If the water in the cell freezes, it will expand and rupture the membrane. Animals that are endothermic (warm-blooded) generate heat within their cells by burning sugar to produce energy. Plants make sugar using light energy. With a few exceptions, they don’t produce heat.

How do trees prepare for winter? They use a process botanists refer to as “hardening.” The cell walls become more permeable to allow water to escape. At the same time, sugars, proteins, and acids in the cell are concentrated into a syrupy liquid, which acts as an antifreeze. The spaces between the cell walls become filled with ultra-pure water filtered through the cell walls. Pure water without stray atoms to form a nucleus around which ice crystals can grow, will freeze only at a much lower temperature. With the cells filled with antifreeze and spaces between having only ultra-pure water that can be super-cooled without freezing, the tree is ready for what the winter brings.

How does the tree know that it’s time to harden for winter? Fall weather can fluctuate quickly and dramatically. A tree can’t depend on the fickle weather because it could easily be fooled by warm days that suddenly turn cold, causing it to freeze to death. Trees know when to prepare for winter because of the length of the days – the “photoperiod.” Weather is unpredictable. The Sun is absolutely dependable. When the tree senses a decrease in light in each 24-hour cycle, it knows winter is coming, even if the weather is unusually warm. The pattern of changing daylight and darkness is exactly the same every year, even though the weather is capricious.

God engineered this incredibly well-designed system. “Then God said, ‘Let there be lights in the expanse of the sky to separate the day from the night. They will serve as signs for seasons and for days and for years’” (Genesis 1:14). Thus God designed the system which says, “Trees prepare for winter.” It’s another engineering marvel from the Creator.

Rhino Horns and Poachers

There’s an amazing balance in the design of living things in this world. Many times humans throw the system out of balance. The rhinoceros is endangered not because of natural predators, but because of humans. Rhino horns can sell for thousands of dollars for their collectible value and their use in traditional Asian medicine, so poachers take advantage of that.

People are willing to pay a high price for the rhino horns for decorative or medicinal purposes. Killing these animals to use their horns for decorative trophies is shameful. Killing them for medicine is useless. Their horns consist of only keratin, which is the same as human hair or fingernails. In reality, the rhino horn is one really tough bundle of nose hairs glued together by material extruded from sebaceous glands in the animal’s nose. Superstitious beliefs have caused people to grind the rhino horns into powder and drink the powder in water or inhale it for supposed health benefits.

Wild rhinos numbered over half-a-million at the beginning of the twentieth century. Today there are fewer than 30,000. The International Rhino Foundation reports that three rhinos are killed each day by poachers just to obtain their horns. Trying to catch the poachers and stop them in the act is nearly impossible. Sawing off the rhino’s horn to make it unattractive to poachers is not a good solution. Science is looking for a better way.

Researchers from the University of Oxford have designed fake rhino horns that look and feel like the real thing. More than that, they have similar material properties to the real horns. They used hairs from the tails of horses (close relatives of rhinos) and cemented them together with a silk-protein based organic filler. Molding the structure into the shape of a rhino horn, you get a realistic imitation. Even examining the internal structure on cross-section reveals identical characteristics. It also handles grinding and high temperatures like the real deal.

These fake rhino horns can be manufactured rather economically, so the rhinoceros horn market could be flooded with them to disrupt the black market. Furthermore, when the horns are ground into powder for medicinal purposes, they will be just as effective real horns, meaning not effective at all.

Education doesn’t work as long as people have superstitious religious beliefs about the power of rhino horns. Perhaps the fake horns will help. The best answer to the problem of human abuse of this well-designed world is to realize that the Creator has given us the job of being caretakers of the creation. (Genesis 2:15) If we believe there is a Creator who holds us responsible, we have good reason to handle the Earth and the life on it with care.

Death of the Marlboro Man

As science began to show the harmful effects of smoking, cigarette companies tried to dissuade fears by adding filters to their products. The Phillip Morris Company initially marketed the Marlboro brand as a cigarette for women. In 1954 the Leo Burnett advertising agency set out to reach a broader market by introducing the Marlboro Man.

Originally the ads featured rugged-looking men in various roles, but in the early 1960s, they settled on cowboys in “Marlboro Country.” The idea was to appeal to young men, “post adolescent kids” by using a masculine cowboy in a ranch setting. One of the men who played the role was a real rancher in Colorado by the name of Robert Norris. Executives at the advertising agency saw him in a newspaper picture with his friend, actor John Wayne. Norris had the looks and the ranch, where the agency took hundreds of photos of him for use in the ad campaign.

The Marlboro Man campaign was so successful that by 1972, Marlboro cigarettes were leading the industry. Robert Norris was not the first, or the last, Marlboro Man. But one interesting thing about him is that he didn’t smoke. In fact, according to his son Bobby, he told his children, “I don’t ever want to see you smoking.” Eventually, one of his children asked, “If you don’t want us smoking, why are you doing cigarette commercials?” That day he called Phillip Morris and resigned from the job.

What can we learn from this? For one thing, as we have said before, human greed causes human suffering. Companies often follow the “survival of the fittest” mentality looking to enhance their bottom line at the expense of the public. Also, as every parent should know, our children will follow our example more than our words.

Norris was the Marlboro Man for 12 years, but he was not the only one. The campaign lasted until 1999. A major reason for its ending was the death of the actors who played the role and actually smoked. Five of them died of smoking-related illnesses. The cowboy theme of the campaign earned Marlboros the nickname “cowboy killers.” Robert Norris, who didn’t smoke, died in November of 2019 at age 90.

Norris’ friend, “six-pack-a-day” smoker John Wayne survived lung cancer in 1964 but died of stomach cancer in 1979. According to the “John Wayne Official” Twitter page, Norris and his wife “spent many Thanksgivings” with John Wayne. Perhaps John Wayne should have followed the example of Robert Norris. My father died from the effects of smoking more than 35 years ago, and this week I lost a friend because he was not able to kick the habit. Meanwhile, those who profit from smoking and vaping continue to demonstrate that they care more about money than people. They need to learn something about the concept of repentance.

What the Mercury Transit Tells Us

What the Mercury Transit Tells Us Above is a photo of the Sun. If you look closely, you will see a small dot in the upper half near the right side. That is the planet Mercury, the closest planet to our Sun. Mercury made what astronomers call a “transit” of the Sun on Monday morning, November 11, 2019. In our area of the country, the sky was overcast, and it was snowing. However, Bill Ingalls of NASA took this photograph from his location in Arlington, Virginia. I find it interesting to consider what the Mercury Transit tells us.

What’s so special about Mercury passing in front of the Sun? For one thing, it doesn’t happen very often. Although the last time was only three years ago, the next time will be in 2032, but it won’t be visible from North America. The next Mercury transit visible in North America will be in 2049. Since Mercury is closer to the Sun, it passes between the Sun and us every 116 days. However, most of the time, it is either above or below the Sun from our view, and Earth’s atmosphere makes it invisible in the daylight.

Scientists used precision telescopes and equipment to study the transit. They can learn more about the atmosphere of Mercury as it is silhouetted against the Sun. Historically Sir Edmund Halley (1656-1742) watched a transit of Mercury and realized that it could be used to measure the distance between the Earth and the Sun. It occurred to him that a transiting planet would appear in different positions to viewers in different locations on Earth. Measuring the apparent shift between two distant Earth locations at the same time and applying a little math, one could calculate the distance to the Sun. In 1769, after Halley’s death, astronomers used a transit of Venus to calculate the Earth-Sun distance.

Think about what the Mercury transit tells us without even seeing it? Because of the fact that astronomers can know in advance the exact date and time of a transit of Mercury (or Venus), or a solar eclipse (when the Moon passes between Earth and Sun) we realize that the solar system is orderly. We can study the heavens and learn of the Creator. We can see His wisdom and design of our planet and the solar system in which it exists. We can know there is a God by the things He has made (Romans 1:20) as the heavens declare His glory (Psalms 19:1).

Moon Record in the Solar System

The solar system record for the largest number of moons has just been taken over by Saturn. Previously Jupiter was the record holder with 79. (Update April 2026- 101.) Now the moon record in the solar system goes to Saturn with 82! (Update April 2026- 285.)

Astronomers used some of the world’s largest telescopes, including the Subaru Telescope in Hawaii to make the recent discoveries. The same team led by Scott Sheppard of the Carnegie Institution for Science in Washington, D.C., discovered 12 previously unknown moons around Jupiter last year. Now they have helped Saturn pull ahead of the competition.

Here we are living on a planet with only one Moon. Should we feel disadvantaged? Not at all! Imagine how confusing it would be to live on a planet with 82 moons. Seriously, one is enough. That is especially true when we have one Moon that is just right. We have pointed out before how precisely well-designed and well-placed our lone Moon is. Here are a few reminders with links to get more information:

Our Moon…
…has just the right mass to stabilize Earth’s rotational tilt.
…is just the right distance from Earth to create beneficial ocean tides.
…is just the right size to create total solar eclipses, which have helped us to learn more about the Sun.
…works with the Sun and stars to “mark seasons and days and years” (Genesis 1:14)
…reflects the light of the Sun to give a night light essential for many forms of life.

Those are a few of the reasons our Moon is the best one in the whole solar system! We asked before, “How many moons are enough?” Even though the number of known moons orbiting Jupiter and Saturn has changed since we asked that question, the answer is still the same. One Moon, precisely designed and positioned, is exactly what we need. We hold the moon record in the solar system for the best Moon of all! There are too many “coincidences” for it to be an accident. We see the work of a Creator, who is an amazing Engineer.
