The Journey to Safety

We have often talked about the design of animals. Various animals act on what we often call “instinct.” Programmed into sea turtles is a journey to safety. When baby sea turtles hatch on the beach, they instinctively and quickly head to the ocean to escape the predators on land. Their mothers didn’t teach them to do that. It is programmed into them. When a kangaroo is born, it will instinctively journey to safety by climbing into its mother’s pouch. She does nothing to assist the tiny creature. Programming a specific action is very efficient, so we program computers to do specific tasks.

In contrast to programmed actions, there is free will. When we tell our children what to do, they may do something entirely different. The child can understand our instructions but still refuse to follow them. The reason is that the child finds other things he wants to do are more appealing.

The bottom line is that commanding actions is less efficient than programming those actions. A baby sea turtle, kangaroo, or robot will act in the way it is programmed. If you are a parent, you have realized that your child will not always do what you command. The question, then, is why didn’t God program humans to do what He wanted? Why did He give us free will? Programming us to act as He desired would have been much more efficient.

God commands us rather than programming us to do His will because He wants to have a relationship with us. Robots can be very efficient because they have specific functions programmed into them and will do what their designer intended. That is not true of humans. However, you can never have a real relationship with a robot. God wants to have a relationship with us. He knew what would happen when He created the first humans, but He did it anyway. We have rebelled and made a mess of our lives and our world. Hatred, war, and mayhem have been the results.

Why, then, did God choose to create us? To Him, having a relationship with us was worth the price. Jesus Christ came to Earth to restore the broken relationship. He was the perfect man, but at the same time, He was God in the flesh. He showed us how to have a loving relationship with God and each other. Then, He bore the punishment for our disobedience to restore the broken relationships.

We are not robots. We are God’s creation, in His image, with free will. We can choose the journey to safety or ignore God and choose our own path. God has made the journey to safety and peace available to us. Why choose the path to destruction?

The Feel-Good Hormones

Hormones are chemical messengers that travel through our bloodstream. You can describe them as signaling molecules that work to set things in motion. The name comes from a Greek word meaning “setting in motion.” Hormones are produced in various areas of our bodies and are sent through the bloodstream to signal some action or response. Good health requires a balance of hormones, and proper diet, exercise, and rest help to keep them in balance. The feel-good hormones are four classes of hormones that, as you might guess, do things that make us feel good.

ENDORPHINS- Endorphins are the body’s natural painkillers. The pituitary gland, located at the base of the brain, synthesizes and stores them. Endorphins help to mask pain, reduce stress, and improve mood. When we push through a painful task or strenuous exercise, endorphins are there to help us.

DOPAMINE- Two areas of the brain produce dopamine, and you can think of this hormone as the brain’s reward system. Exercise, eating a food we like, or accomplishing a task can cause the brain to release dopamine, giving us a pleasurable feeling. The use of some drugs and alcohol can release a flood of dopamine, giving us a sense of euphoria, a “high.” But coming down from that high can lead to depression and a desire for more of the drugs. Normal activities or exercise stimulate dopamine more slowly, and the effect of the hormone remains longer. Good stewardship of our bodies and health calls for avoiding harmful drugs and alcohol.

OXYTOCIN- Some people call this feel-good hormone the love hormone. Touching, hugging, or sexual activity can trigger the release of oxytocin. The brain’s hypothalamus produces it, and the pituitary gland releases it into the bloodstream. Oxytocin can help improve social interactions and give us a desire to develop stronger connections with others.

SEROTONIN- Serotonin is a natural mood booster, and depression can result from a low level of this hormone. Serotonin performs many functions and is produced by the central nervous system in various areas of the body. Serotonin improves memory and learning and promotes relaxation. Exercise, as well as exposure to sunshine and the outdoors, can increase the production of serotonin. Meditation and quietness in prayer can also reward us with this mood-boosting hormone.

The feel-good hormones are part of good health, and a healthy lifestyle boosts them. However, too much of a good thing too quickly is not healthy. Alcohol and drugs can give us a high but only lead to a letdown. A healthy lifestyle involves proper diet, exercise, rest, prayer, meditation, thankfulness, and balanced relationships with others. Incorporating those things into our lives is the best way to enjoy the blessings God has for us.

Biological Complexity in Living Organisms

Those who advocate for naturalistic evolution have a problem. Well, they have more than one, but this one is a math problem. In a publication on the National Institutes of Health’s Pub Med website, Alexei A. Sharov presents a dilemma for evolutionists. Simply stated, the size of the genome indicates biological complexity in living organisms, while macro-evolution requires exponential growth to achieve that biological complexity.

Perhaps this will be easier to understand if we relate it to Moore’s Law in semiconductor technology. In 1965, Gordon Moore of Fairchild Semiconductors and Intel projected that the number of components in each integrated circuit would double yearly. In 1975, the prediction was revised to every two years. It took on the quality of a “law” as the semiconductor industry used it as their target for planning production. Moore’s Law has led to technological changes that produced economic growth and social change. The point is that doubling the complexity of electronic technology means a logarithmic increase in versatility, as we have seen over the years.

Alexei Sharov applied that principle to evolution based on the exponential growth in biological complexity. Using the exponential increase in biological complexity in living organisms as a guide, it is possible to go backward in evolutionary time to see when life began. If the exponential hypothesis is true, tracing back in time, the origin of life would have been ten billion years ago. That is how long it would take for the genome to evolve to its present complexity in mammals. No evolutionist or other scientist believes our planet is that old. That presents a math problem for naturalistic evolution.

So, what do Sharov and others propose as the solution? They call it “panspermia,” meaning that life came to Earth from outer space. Nobel Prize winners Fred Hoyle and Francis Crick were advocates for panspermia. However, most evolutionary scientists reject it. Perhaps there is a better way to explain the fact that naturalistic evolution does not fit into Earth’s timeline. The solution, soundly rejected by Hoyle and Crick, is the idea of a Creator outside of time and space who designed the universe and life and put us on this planet for a purpose.

Afraid of the Facts

We should never be afraid of the facts when they are accurately presented. U.S. President John Adams said, “Facts are stubborn things; and whatever may be our wishes, our inclinations, or the dictates of our passion, they cannot alter the state of facts and evidence.”

Last week, we looked at James Tour’s challenge to the leading origin-of-life scientists. None of them were willing to address even one of the five roadblocks to abiogenesis that he presented. The fact is that the study of abiogenesis, the origin of life from non-living matter, has progressed very little in the last 70 years. Science has found many barriers to abiogenesis since the Miller-Urey experiment of the early 1950s.

Quora is a social media question-and-answer website where people post questions and others respond with answers. A recent questioner asked, “Are scientists terrified of abiogenesis?” A person who said he was “45 years a physician” answered that he was not afraid of abiogenesis. Part of the response from the “physician” was:

“Abiogenesis is a process that occurred at least once in the history of the earth, and that single event (or handful of events) may have left no traces at all. The steps in abiogenesis were probably a series of unknown physical and chemical steps. So, the process may never be known.”

Saying that “unknown physical and chemical steps” in a “process may never be known” is a vague answer. He seems to be saying, “I’m not going to worry about that because it scares me.” As I said, people should never be afraid of the facts.

Genesis chapter one uses the Hebrew word “bara,” which is always used to describe something that only God can do. Verse one describes God creating the heavens and Earth out of nothing. Verse 21 uses that word again to describe the creation of the first animal life. Between those verses, the term “made” (Hebrew “asah”) or the words “let there be” describe God’s work.

Science has made significant progress in understanding the processes described by “made” and “let there be.” In some cases, scientists have even duplicated those processes in laboratories or particle accelerators. However, understanding how God created everything from nothing or life from non-living matter is beyond what science has accomplished or perhaps will ever understand. Christians should never be afraid of the facts because they point to a creator God.

World of Life Beneath the Soil

An unknown world of life lurks beneath our feet, and we should be thankful that it does. A research report in the Proceedings of the National Academy of Sciences (PNAS) says that approximately 59% of all living species on Earth live in the soil. Because there are so many organisms living there and they are generally out of sight, scientists don’t know how many species exist in the world of life beneath the soil.

According to the report by Diana Wall of Colorado State University, Fort Collins, soil organisms support life above the soil in many ways. They make it possible for us to grow food, and they break down organic waste. We often think of earthworms, but there are also many smaller worm species. We seldom see various insects that spend their lives in the soil. However, we do see insects that live much of their lives under the ground as well as above. Those include ants, springtails, woodlice, and millipedes. We often think of some animals that live in the soil as pests, such as termites and nematodes. However, they serve the purpose of breaking down organic materials, helping to keep the world from filling up with waste.

Plants also live in the world of life beneath the soil. For example, fungi do not use photosynthesis like green plants, so they can survive in the darkness. Subterranean life forms include the least familiar amphibians, the caecilians, whose name means “blind ones.” Naked mole-rats live underground, and many other mammals spend at least part of their lives in subterranean darkness.

According to the report in PNAS, “soil is the most biodiverse singular habitat.” We don’t often think of the world of life beneath the soil, but we should thank God that He thought of it. Subterranean life makes it possible for life above ground to thrive and prosper. We see this incredible web of life as evidence of design.

Tragedies Do Not Disprove God

On Saturday, November 11, U. S. soccer star Megan Rapinoe had a career-ending injury. Only six minutes into the National Women’s Soccer League Championship, Rapinoe tore her Achilles tendon, putting her out of the game. She used the occasion to express her lack of belief in God. The truth is that tragedies do not disprove God.

In the post-match press conference, Rapinoe said, “I’m not a religious person or anything, and if there was a god, like, this is proof that there isn’t.” She then went on to express her feelings in profanity. Rapinoe admitted that she was not a believer before the accident. But I would ask, what does this accident have to do with God’s existence? Tragedies do not disprove God.

When we read the book of Job, we see the tendency of people to think that when something terrible happens, it means that person has done something bad and God is punishing them. The opposite of that is believing that if something good happens to us, we must have done something good to deserve it. Both concepts are false, contrary to Biblical teaching, and illogical.

Jesus clearly said that His followers would suffer for doing good. Paul suffered for presenting the gospel message of love and hope to a world that needed to hear it. James said, “Count it all joy when you fall into various trials, knowing that the testing of your faith produces patience. But let patience have its perfect work, that you may be perfect and complete, lacking nothing” (James 1:2-4).

When things go wrong, people often blame God. Some turn away from God, and others turn to God. Turning away from God is turning away from hope. Seeking God in times of trouble brings hope and, as James tells us, develops patience. Tragedies do not disprove God. They have nothing to do with God’s existence, and rejecting God because of disasters provides no hope. Placing our faith in God in difficult times gives us a source of hope and comfort.

Rapinoe expressed her confused perspective when she went on to say, “Thank God I have a (expletive deleted) deep well of a sense of humor.” I believe it takes more than a sense of humor to survive the trials of life. It also takes hope. “Therefore, having been justified by faith, we have peace with God through our Lord Jesus Christ, through whom also we have access by faith into this grace in which we stand, and rejoice in hope of the glory of God (Romans 5:1-2).”

James Tour Challenge

How did non-living chemicals become living plants and animals? Origin of life research has been the focus of countless hours and vast expenditures by expert scientists for the last 70-plus years. The results have been, well, unremarkable. Chemist Dr. James Tour of Rice University issued a 60-day challenge. The James Tour challenge to the leading origin-of-life researchers called for them to show what progress they have made in 70 years.

Dr. Tour points out that there are five major hurdles that the origin-of-life scientists must clear. They are the fundamental problems that stand in the way of life originating from non-life (abiogenesis). In simplified form, they are:

Linking amino acids into chains
Linking nucleotides into RNA molecules
Linking simple sugars into chains
The origin of biological information
The assembly of all components into a cell

YouTubers are claiming that scientists have completely solved these obstacles to abiogenesis. If that is true, Tour challenged the leading origin-of-life researchers to verify and explain it. The James Tour challenge gave them 60 days to put up their evidence. Dr. Tour said if they could show that they have solved even one of those problems, he would shut up about the issue.

The James Tour 60-day challenge expired at the end of October 2023. Not one scientist could meet his challenge. In other words, in 70 years of research, no progress has been made on any of the major roadblocks to non-living matter becoming a primitive living cell.

If brilliant scientists with the best equipment and modern laboratories ever manage to produce life from basic elements, what will they prove? They will not show that life can originate by unguided accidents. They will have demonstrated that an intelligent being can create life from non-living matter. That is what the Bible has said for thousands of years.

How the Mpemba Effect Works

Yesterday, I warned of the danger of trying to solve an argument using the scientific method when people want to stick to their preconceived ideas. The argument I referred to was between my family members about whether hot or cold water freezes faster. The truth is that the phenomenon where hot water freezes faster is called the Mpemba effect after an African secondary school student who brought it to the attention of a British physicist. Even though it had been observed since Aristotle’s time, most people didn’t believe it, and nobody seriously attempted to explain how the Mpemba effect works.

Perhaps the reason science ignored the Mpemba effect is because it seems illogical and unreasonable. In 2013, Xi Zhang and colleagues at Nanyang Technical University in Singapore presented a possible solution to how the Mpemba effect works. Water molecules contain one atom of oxygen bonded to two atoms of hydrogen (H₂O). The oxygen atom shares an electron with each hydrogen atom in what is known as covalent bonding.

In addition to the covalent bonding within the water molecules, the separate molecules are held together by hydrogen bonds. Water molecules are polarized, and since water is a liquid, the molecules move around. When a hydrogen atom in one molecule is close to the oxygen atom in another molecule, hydrogen bonds loosely hold them together. Hydrogen bonds explain the surface tension of water, its relatively high boiling point, and how the Mpemba effect works.

As water is heated, the molecules move faster, stretching the hydrogen bonds, causing them to store energy, and allowing the covalent bonds to relax and give up some energy. Covalent bonds giving up energy is equivalent to cooling, allowing the heated water to freeze faster. In a 2017 issue of the Journal of Chemical Theory and Computation, Yunwen Tao and co-authors described using vibrational spectroscopy and modeling to show that hydrogen bonds can explain how the Mpemba effect works.

Other factors can be involved in water freezing to counter the Mpemba effect. Dissolved gases or other impurities, convection currents, evaporation, and even the container can influence the time it takes for water to freeze. The relative initial temperatures and consistency of the water samples are also critical factors.

The bottom line is that the design of water is an essential factor that makes life possible. We have said that before: HERE, HERE, HERE, HERE, and HERE. The fact that hot water can freeze faster than cold is hard to believe, but true. Even harder to believe is that the design of water, the universe, our planet, and life could be accidental, but atheists still argue that those designs all happened by chance. I challenge you to carefully consider where you stand on the existence of a creator God.

Does Hot or Cold Water Freeze Faster?

As a young boy, I learned not to try to solve family arguments between my elders. My father told my aunt (his sister) that he had heard that hot water freezes faster than cold water. She said that could not be true, and that led to a heated argument between them. I thought this was not something worth arguing about, and I suggested that we test the theory by the scientific method. Does hot or cold water freeze faster?

Thinking I could settle the argument, I suggested we fill one ice-cube tray with hot water and one with cold water, put them both in the freezer and see what happens. This suggestion from a young “whippersnapper” brought down the wrath of both sides. I realized that they didn’t want to know the truth. They just wanted to argue. Perhaps they were both afraid they might be proven wrong. I have since learned that believers and skeptics often fear looking at evidence for that very reason.

So, does hot or cold water freeze faster? The short answer is that it depends. Some famous thinkers, including Aristotle, Francis Bacon, and Rene Descartes, noticed that hot water sometimes froze faster than cold water. But it took a Tanzanian secondary student making ice cream in 1963 to finally bring this question into scientific focus.

Young Eraso Mpemba, along with fellow students at Magamba Secondary School, was making ice cream to earn some money. He was in a hurry, so rather than letting it cool, he put the hot ice cream mix into his freezer. He was surprised that his ice cream froze faster than the colder mix of his fellow students. Mpemba’s teacher and classmates laughed at his claim that the hot mix froze faster.

Later, a noted British physicist named Denis Osborne came to the African school, and Mpemba asked him to explain why hot water freezes faster than cold. Not only did his teacher and classmates think Mpemba’s suggestion was absurd, but the physicist was also skeptical. However, Dr. Osborne was open-minded enough to test it experimentally. (Like I suggested to my father and aunt.) In 1969, when Mpemba was in college, he and Osborne published a paper on the phenomenon, which came to be called the Mpemba effect.

So some people, when asked, “Does hot or cold water freeze faster?” were no longer laughing at the “foolish question.” However, nobody knew how hot water could freeze faster. After all, if the water is already closer to freezing temperature, it should freeze in less time. Shouldn’t it? The truth is that the question does not have a simple answer. In 2013, scientists in Singapore proposed a solution. Tomorrow, we will look at their explanation.
