How to Deal with Death

One of the most significant challenges of our time is how to deal with death, and as medical science advances, the issue becomes more critical. Some project that by the year 2050, the U.S. government will spend a trillion dollars a year on millions of institutionalized Americans with Alzheimer’s and advanced stages of dementia. That is 50% more than all federal, state, and local agencies spend today on K-2 public education.

On a more personal level, Americans often spend the largest amount on medical care during the last year of life, depleting family resources and frequently leaving surviving family members destitute. I personally know of widows in our area who are living on a day-to-day basis because they spent all their savings caring for a dying husband.

Medically assisted suicide is the current trend in how to deal with death. Ending one’s life at a time and in a place of their choosing is now legal in Australia, Austria, Belgium, Canada, Colombia, Luxembourg, the Netherlands, New Zealand, Spain, and Switzerland, where it has been legal since 1942. Organizations worldwide and in the United States assist people in arranging legal medically assisted suicide.

At the moment, there are ten states and the District of Columbia that have medically assisted right-to-die programs. This trend began on November 22, 1998, when 60 Minutes broadcast a video of Michigan physician Jack Kevorkian administering voluntary euthanasia to Thomas Youk, a 52-year-old man with advanced Lou Gehrig’s disease. Oregon passed the nation’s first “death with dignity” law four years later, and other states followed after 2016.

In Canada, a person can end life as young as 18 and need not have any life-threatening illness. In 2021 over 10,000 Canadians ended their lives through state-approved euthanasia. This statistic highlights a significant “slippery slope” problem with euthanasia or assisted suicide laws. They can expand to include people who have minor mental or social struggles.

St. Thomas Aquinas wrote, “It is altogether unlawful to kill oneself because life is God’s gift to man and subject to His power, Who kills and makes to live. Hence whoever takes his own life sins against God.” In 1 Corinthians 3:16-17, Paul wrote, “Do you not know that you are the temple of God and that the Spirit of God dwells in you? If anyone defiles the temple of God, God will destroy him. For the temple of God is holy, which temple you are.” There is no easy answer to this question of how to deal with death. However, many of us will face the hard choices the end of life can bring.

How the Elements Were Crafted

One of the great mysteries of science has been the question of how the heavier elements came into existence. Physicists have produced a few heavy elements in particle accelerators, and they have observed them being made in stars. Understanding how the elements were crafted is a solid apologetic for God’s creative power and wisdom. Being able to duplicate in a laboratory what God has done in the vast outreaches of space increases our amazement at what God has done.

As we said yesterday, the ability to produce nuclear fusion may solve our energy needs, but the fact that God did it “in the beginning” has led to a greater appreciation of God’s power and His methods. We know that the nuclear fusion of hydrogen can produce helium. We can duplicate that process in the laboratory on a small scale and see it in operation in the Sun.

Hydrogen (1) was produced first, but forging elements, including carbon (6), nitrogen (7), and oxygen (8), required enormously high pressures and temperatures in the interior of stars. These elements are the four starting points for life—still heavier elements require even greater pressures and temperatures.

In 1987, astronomers watched a star explode, becoming supernova 1987a. After the explosion, astronomers detected neon (10) in the star, which was not there before. Direct and indirect observations of the nuclei of exploding stars has shown how the elements were crafted as God produced the following 28 elements in the periodic table. This group includes copper and phosphorus, which are present in our bodies and are essential to life.

As our cosmic tools have become capable of detecting gravitational waves, we have seen even heavier elements produced when neutron stars collide. For example, computer models have shown that those collisions can produce the elements gallium (31) through bismuth (83). In addition, the merger of two black holes can produce very heavy elements such as thorium (90) and uranium (92). The bottom line is that we can see how the elements were crafted by God. He made the universe and our bodies from elements produced in the core of ancient stars.

Obviously, the Bible doesn’t explain how the elements were crafted. However, it does tell us that God acted “in the beginning” to set the process in motion. As we observe the universe through new tools such as the Webb Telescope with the help of computers, we can see a vivid display of God’s power and wisdom in creating all that we see and are. For most of us, “In the beginning, God created” is all we need to know, but as science learns what it takes to create the building blocks of creation, we have a whole new appreciation of “the heavens declare the glory of God and the expanse proclaims the work of his hands” (Psalms 19:1 CSB).

Nuclear Fusion to Power the Future

People today are concerned about “green energy.” The government is attempting to move the economy away from fossil fuels to protect the environment and reduce climate change. However, all of the alternative power sources have limitations. What we need is nuclear fusion to power the future.

Presently, the favored alternatives to fossil fuels are wind and solar, both of which have drawbacks. They include the expense of installing and maintaining them, plus the fact that sunshine and wind are only sometimes available. In addition, there are few locations where water power is feasible, and building dams on rivers can cause other issues. Nuclear fission is probably the most efficient method of generating electric power without putting carbon in the atmosphere. However, past catastrophes cause people to fear that option. Plus, nuclear fission creates waste that will be radioactive for years, and we have no place to store it.

On the other hand, nuclear fusion can release massive amounts of power. After all, that’s what powers the Sun and other stars. With nuclear fusion, there is no radioactive waste and no carbon to create greenhouse gases. The byproduct produced is helium, a useful resource in short supply.

Nuclear fusion to power the future sounds like the answer to all of our problems, so why aren’t we switching to it now? The problem is that science hasn’t found a practical way to do it. However, in December 2022, scientists at the Lawrence Livermore National Laboratory in California produced nuclear fusion in a lab. The tiny reaction was nowhere near what the Sun does, and it lasted only trillionths of a second. But it was a start. Thirty private fusion companies worldwide are using the Livermore breakthrough as a pattern to promise clean energy that would outpace wind or solar, or anything else we now have. The Fusion Industry Association suggests they could generate fusion electricity sometime in the 2030s.

Is nuclear fusion to power the future just a pipe dream, or could it really happen? God has given us everything we need for an advanced civilization. Intelligent planning of Earth’s history provided the fossil fuels needed to bring us into the modern age. Einstein’s equation e=mc² revealed the enormous power contained within each atom. By releasing some of that power, we have generated electricity by nuclear fission. By applying the intelligence God gave us, we can go a step further and release even more power through nuclear fusion. That could get us away from depending on energy sources that are unreliable or pollute the atmosphere.

The truth is that tiny atoms are held together by incredible power, and releasing that power can solve our energy needs. The power that holds every atom together had to have a source—the One who created everything and holds everything together. “[Jesus Christ] is the image of the invisible God, the firstborn of all creation. For by him all things were created, in heaven and on earth, visible and invisible… And he is before all things, and in him all things hold together” (Colossians 1:16-17 ESV).

Darwin’s Racism and Sexism

Evolutionists and critics of Christianity are fond of attacking the Christian faith as the source of every evil in our culture today. They pay little attention to the fact that Charles Darwin’s education and culture indoctrinated him with sexist and racist narratives. Darwin’s racism and sexism show up in his writings.

Darwin presented his erroneous views as scientific facts. Here are some of Darwin’s beliefs as clearly expressed in his 1871 book The Descent of Man:

* Men are evolutionarily superior to women.

* Europeans are evolutionarily superior to non-Europeans.

* Hierarchical civilizations are evolutionarily superior to small egalitarian societies.

* “The hideous ornaments and equally hideous music admired by most savages are not so highly developed as in certain animals, for instance, in birds.”

* The appearance of Africans is comparable to the New World monkey Pithecia satanas.

* The subjugation of the poor, non-Europeans, and women was the natural result of evolutionary progress.

It is not difficult to understand how Darwin justified racism from an evolutionary standpoint. Darwin received a state funeral in Westminister Abbey and was publicly commemorated as a symbol of “English success in conquering nature and civilizing the globe during Victoria’s long reign.” To this day, we have skeptics using Darwin’s work as a club against Christians and belief in God while attacking Christianity as the source of evil. Even as he described evolution by natural selection (which we have pointed out has been recently challenged by new research), Darwin’s racism and sexism remained part of his scientific writing.

In today’s world, educated people can be heavily influenced by their peers and culture. They can still be captive to cultural bias, as Darwin was. The Christian system is unique in opposing all distinctions of race, sex, and culture, loving all people, and treating everyone as created in God’s image. (See Matthew 5:43-48 and Galatians 3:27-28.)

Waste of Food and Resources

One of the great tragedies of American culture today is the incredible waste of food and resources. People in many places around the world are surviving on less than 1000 calories per day, and starvation is killing vast numbers. Over a third of the food produced in the United States is never eaten. On average, Americans throw away a pound of food per person daily. The Environmental Protection Agency says the water and energy wasted in the United States in a year would supply more than 50 million homes.

The problem is not just the waste of food and resources but also how we use the land to produce food. The University of Oxford and Global Change Data Lab tell us that 50% of the world’s habitable land and 70% of freshwater goes to growing food and raising livestock. So when we throw away food, we also waste land and water resources. Three-fourths of the global ocean and freshwater pollution comes from agriculture. Greenhouse gas emissions from one year of food waste in the United States alone are equivalent to the emissions from 42 coal-fired power plants.

God has provided us with all the resources we need to feed the world’s population, but corporate greed, selfishness, ignorance, and a lack of concern for others cause the problem of world hunger. In Matthew 25:31-46, Jesus described judgment based on how we conduct ourselves in meeting the needs of others. The first thing Jesus mentions is that providing food for others is a responsibility of His followers (verses 35 and 42). One way we can do that is by avoiding the waste of food and resources God has given us and becoming leaders in the war against hunger. By living in obedience to Christ, we witness the reality of God to the world.

Reference: The Tufts University Health and Nutrition Letter for February 2023 has several tips for reducing food waste, including “the truth about date stamps” on food that cause people to throw away food that could be eaten.

Eliminating Pigments in Paint

What if we could reduce environmental problems by eliminating pigments in paint? Creating colorful paint without pigments is possible by copying something found in the natural world. For example, butterflies, birds, fish, and cephalopods use structural color to create their dazzling beauty. Light, rather than pigments, creates structural color.

Debashis Chanda and colleagues at the University of Central Florida have researched eliminating pigments in paint by using structural color. Pigment colors are artificially synthesized molecules, requiring different chemicals for each color. Structural color involves producing a geometrical arrangement of two colorless materials to make any color of the rainbow.

Chandra’s work produces a plasmonic paint using nanoscale structural arrangements of aluminum and aluminum oxide, both of which are colorless. Structural color controls the reflection, scattering, or absorption of light based on the geometrical configuration of the nanostructures. The research has placed these structural color flakes in a commercial binder to produce all the colors visible to the human eye.

Unlike pigment color, structural color never fades. Another advantage is that it reflects infrared radiation, so the material under the paint can stay 25 to 30 degrees F cooler than with chemical paint. Also, plasmonic paint is lighter weight because it can produce saturated colors with a thinner paint layer. In addition, since the colors will not fade, there may not be a need to repaint as often. Finally, eliminating pigments in paint reduces chemical substances that can cause environmental impacts.

With these advantages, structural color plasmonic paint may be the paint of the future. Interestingly, structural color is another thing we learn from studying the natural world. Often the colors we see in living things come from structural color rather than pigments. This is one more example of the intelligence God built into the world. We continue to learn exciting new ways to improve people’s lives by mimicking what God has already done. Like velcro, penicillin, bird wings, and lizard lungs, we are blessed by copying God’s design.

Tool Use Discoveries in Anthropology

Scientific articles about tool use as an indicator of pre-human activity in the distant past may have to be rewritten. New discoveries show that the “tools” some anthropologists claimed were used by ancient hominids may be stone flakes accidentally created by monkeys.

Researchers have observed long-tailed macaques in Thailand using rocks to pound open palm nuts. When they use rocks containing flint or quartz, they create flakes or shards. Those fragments are very similar to some sharp-edge stone fragments researchers previously thought were created by ancient humans in East Africa.

Scientists have used what they call intentionally produced sharp-edged stones as proof of the evolutionary development of emerging humans. They used the “flake technology” to infer the degree of cognitive ability, including knowing how to select the types of rocks to give specific properties for making tools. Despite this “new” research, experienced field workers had previously observed monkeys inadvertently producing stone flakes and sometimes even using them as grooming tools.

Today’s anthropologists have moved beyond tool use to determine whether a specimen was human. They can sometimes use DNA found in the remains of the individuals. DNA studies have led to the understanding that all humans are related and that the gene pool has been thoroughly mixed over the ages.

The biblical reference is very simple. The name “Eve” means the mother of all living humans (Genesis 3:20). “Adam” means “of the ground,” referring to the fact that our physical bodies consist of elements found in the earth. “In the sweat of your face shall you eat bread until you return to the ground, for out of it you were taken. For dust you are, and to dust you shall return” (Genesis 3:19).

What sets humans apart is not tool use but our spiritual makeup. All humans are made in the image of God. We are all one physically, and the Bible calls us to become one spiritually. (See Galatians 3:28 and Ephesians 2:14.)

What Are the Chances?

Advocates of unguided naturalistic evolution say that evolution could have gone in many directions, and we are lucky to be here. But what are the chances of evolution producing you and me as we are today? Evolutionists would say the changes are 100% since we are already here. But, if we go back to the cosmic creation event, or “big bang,” the chances that we would have evolved are nil. On the other hand, if God planned and guided the creation because He had us in mind, the chances are 100%.

The DNA that makes us who we are physically is a highly complex strand of information. What are the chances that it could have written itself by chance? First of all, information comes from intelligence, not chance. Calculating the likelihood of something after it has happened is a statistical fallacy. After all, DNA is here, and so are we, so the chances are 100%. But what are the chances if we go back before the fact? What are the chances that non-living chemicals could come together in a just-right way to form the first living cell? Then what is the statistical evidence for that first cell multiplying and modifying by random chance mutations and natural selection to create humans?

One imagined scenario involves a billion chimpanzees typing on a billion keyboards for a billion years, accidentally typing one line of Shakespeare. What are the chances of that? Well, the short answer is that it will never happen. Computer keyboards have various numbers of keys, but the old-fashioned typewriters had 58, so let’s go with that number.

Forget Shakespeare. Look for the line “I love you more.” without quotation marks. That is a total of 16 letters, spaces, and a period. With 58 keys and 16 letters, what are the chances of accidentally typing that line? To compute that, you would have to multiply 58 X 58 X 58 X 58 X 58 X 58 X 58 X 58 X 58 X 58 X 58 X 58 X 58 X 58 X 58 X 58. That is a total of 16 times. If you want to try it, go ahead, but it will probably exceed the capacity of your calculator. The answer would be 16.4 trillion quadrillion typing attempts.

Typing continuously at a speed equivalent to 45 words per minute, it would take 2,100 trillion years to have a 50/50 chance that one of those chimps would type that phrase. Absolutely nobody thinks that the Earth is anywhere close to 2,100 trillion years old. Nobody even suggests that the universe is that old. For this thought experiment, we are only looking for one short line of text, “I love you more.” That is nothing compared to the complex system of life on this planet.

The bottom line is that we can’t explain life or the fine-tuned physical constants of the universe by chance alone. But we can explain those things if God planned and guided the creation because He had us in mind. With God, our chances of being here were 100% from the beginning. (See Genesis 1:1.)

Spring Green Testifies of God

I have been admiring the beautiful colors of the blossoms on our fruit trees and the flowering dogwoods. Spring brings new life to the natural world. Everything changes daily as the bulb plants wake up and emerge from the ground. Yet, even with all the beautiful colors, I enjoy spring green.

Green is a very relaxing color. The new leaves on the trees transform them from ghost-like stalks to luxurious, living umbrellas ready to provide shade from the summer heat. But, have you ever noticed that the green of tree leaves seems more vibrant in the spring than in summertime? There is a reason for that. It isn’t just your imagination.

Leaves are green because of the chlorophyll they contain. That amazing chemical makes it possible for plants to take energy from the Sun, moisture from the ground, and carbon dioxide from the air to make sugars that power their growth. We call that extremely complex process photosynthesis, and we have discussed that before on this website. The chlorophyll is contained in chloroplasts in the leaves. The chloroplasts absorb light, but they use more of the higher energy blue and red wavelengths and reflect much of the green. When we see spring green leaves, they contain fewer chloroplasts, so they absorb less light, making the green leaves appear bright and vibrant.

Chloroplasts multiply as the season wears on, so the leaves absorb more light. Also, the cuticles, or outer layer of the leaves, and the cell walls in the leaves become thicker. Those factors, which are part of the leaf’s maturing process, cause it to appear darker. I wonder if we also become less conscious of the green after we have seen it for a few weeks. When the dark tree trunks of winter become hidden by beautiful green leaves, we take notice. Our attention changes when we have seen the spring green and become overwhelmed by the summer.

In autumn, when the chloroplasts fade, the vibrant colors of other chemicals in the leaves catch our attention. Spring green and autumn gold and red can jar us into realizing the beauty of the world. However, we should not need sudden changes to make us conscious of the beauty of God’s wonders all around us. Evidence for God is there if we are willing to look. “For his invisible attributes, that is, his eternal power and divine nature, have been clearly seen since the creation of the world, being understood through what he has made. As a result, people are without excuse” (Romans 1:20 CSB).

Elephants Show Design and Purpose

Skeptics have maintained that our planet cannot support animals as big and requiring as much food and water as elephants. Such comments are a product of ignorance and the desire to show that a wise Creator could not have designed life on Earth. However, the more we learn about them, the more we see that elephants show design and purpose.

Elephants eat 200 to 300 pounds of food and drink up to 40 gallons of water every day. They can spend 75% of their day eating, and that fact has fueled the skeptical view. What needs to be better understood is that almost 50% of the plant material they eat leaves their body undigested. This makes the elephant the gardener of the rainforest, providing seeds and water in places that would otherwise be barren.

An elephant’s trunk is an incredibly sophisticated piece of equipment with 40,000 muscles that can bend in nearly any direction. An adult elephant’s trunk can pick up a 700-pound weight, but it is sensitive enough to pick up a flower. Elephants can suck up and expel water but do not drink through their trunk – it is not a straw. An elephant’s sense of smell is twice as keen as a dog’s and can detect the scent of food or water 10 miles away.

Elephants use infrasonic sounds to communicate with one another. These are frequencies lower than 20 cycles per second, the lower limit of human hearing. Using low frequencies allows the sounds to be transmitted over very long distances. Studies have shown that elephants can communicate with one another over a span of six miles. Elephant hearing does not just involve its ears. They also hear through nerves in their feet, and their hearing is sensitive enough to distinguish between human voices.

Elephants have the largest brain of any land animal, and the memory section is larger and denser than that of humans. The adage of having a memory like an elephant recognizes this ability, which has shown to be useful in situations such as remembering where water holes were 12 years ago. The design of elephants is so complex that attributing it to blind chance does not seem to be the best explanation. Seeing that elephants show design and purpose, we recognize that life is the product of an intelligent Creator.
