Rest of the Story on Gene Editing

Rest of the Story on Gene Editing
Many years ago there was a well-known radio news personality named Paul Harvey. He made a career out of digging into details on stories that were not publicized by the media. He called the reporting “The Rest of the Story.” People close to Harvey said that he got some heat from media people who felt he had made them look bad by revealing details they missed. With the general public, however, he was very popular. We want to examine the rest of the story on gene editing.

There has been a great deal of media reporting about CRISPR-Cas9 which is a tool for editing DNA introduced in 2012. Researchers hope that science can treat a wide range of genetic diseases by altering human DNA. The problem is that our understanding in this area is very primitive. Bioethicists writing in the Wall Street Journal (December 15, 2018, page C3) report, “scientists have only begun to understand what the tens of thousands of individual genes do. Moreover, they are far from unraveling how those genes interact with each other.”

When researchers deleted a gene that limits muscle growth in rabbits, the rabbits had enlarged tongues. Doing the same thing with pigs produced additional vertebrae. In calves the change caused the calves to die prematurely. Lambs grew too large in the womb to be born naturally. Lisa Moses who is a bioethicist at Harvard says, “Humans have a long history of messing around in nature with all kinds of unintended consequences. It’s really hubris of us to assume that we know what we are doing and that we can predict what kinds of bad things can happen.”

There are lessons to learn here. CRISPR has the potential to correct damage to DNA caused by human carelessness, pollution, and mismanagement. The rest of the story on gene editing is still to be written. When a Chinese scientist claims to have produced the first gene-edited human babies, there has to be immediate condemnation by the scientific community. Over the years, outstanding scientists have pointed out that science lacks the capacity to determine the use of its discoveries.

We desperately need Christians who are capable scientists using their faith in God to determine those uses. Will CRISPR be used to eliminate genetic diseases, or will it be used by political demagogues to produce pathogens that kill millions of innocent people? The Nobel Peace Prize was started by a man who discovered dynamite and was appalled at the way it was being used to fight wars. That kind of sensitivity is needed in today’s genetic research to write the rest of the story on gene editing.

Another lesson in all of this is that the complexity of the genetic code of life cannot be the result of chance – a blind watchmaker as some have suggested. Wisdom calls out in Proverbs 8, “O you simple ones, understand wisdom … for wisdom is better than rubies; and all things that may be desired are not to be compared to it. I wisdom dwell with prudence and find out knowledge of witty inventions … The Lord possessed me in the beginning of His way, before His works of old … Hear instruction and be wise and refuse it not.”

Thinking Outside the Brain

Thinking Outside the Brain
Our bodies feed sensory information into the brain, sort of like a keyboard, mouse, or scanner feeds data into a computer. There is a school of psychology known as “embodied cognition” which suggests that not all of our thinking takes place in the brain. They suggest that we do some of our thinking outside the brain.

Those scientists say that the body helps the brain decide what to do with the data it receives. In one test, volunteers were directed to stand at the bottom of a hill and estimate how steep it was. The answers given correlated with the physical condition of the volunteers. Those who were not physically prepared to climb the hill estimated it to be steeper than it was. Those who were carrying a heavy backpack estimated the hill to be steeper than those who were not carrying a load. A physical challenge of any kind may look easy to a person who is physically ready for the challenge. To a person with disabilities, the same task looks much different.

The way we perceive the world is linked to our physical state. The idea of facing a new day is difficult for a person who is in pain. To a healthy person, the new day may be filled with exciting possibilities. A happy person may thank God for blessings. To a person who is discouraged or depressed the concept of a loving God may be hard to accept. Our bodies may be giving our brain a discouraging message.

Sometimes we need to be thinking outside the brain — even outside our bodies. We need to allow faith to tell us something more than our eyes can see and more than our bodies can feel. Another test by those investigating embodied cognition showed that looking upward influences people to think of others who are more powerful than they are. We suggest that looking up to God and putting faith in Him can change our perspective on the challenges of each day.

Design Is an Illusion – Not

Design Is an Illusion – Not
If you read our posts and publications regularly, you probably know that we are continually talking about design in the universe, on our planet, and especially in living things. We think that it is impossible to look at life and say that we see no design. However, some people can see the same things and say design is an illusion. They are willing to accept on faith that everything came into existence out of nothing and evolved by pure accident with no intelligence involved.

One person who refuses to see design in nature is a very well-known evolutionary biologist. Richard Dawkins has written several best-selling books that are supposed to be on the subject of biology. However, they are actually books on theology. The high point (or low point) of his books on theology is The God Delusion (Houghton Mifflin 2006). He travels the world giving lectures on theology, under the guise of biology.

Dawkins’ field of study is biology, not theology, so we take his pronouncements with a grain of salt. However, even Dawkins has to admit that his biological studies appear to show design. In his book The Blind Watchmaker he wrote, “Biology is the study of complicated things that give the appearance of having been designed for a purpose.” However, he then goes into theology by stating that design is an illusion and there is no designer. That means there is no ultimate purpose in life beyond day-to-day survival. In River Out of Eden Dawkins wrote, “The universe we observe has precisely the properties we should expect if there is, at bottom, no design, no purpose, no evil and no good…”

No design, no purpose, no evil, and no good—that’s the way Dawkins describes the living things he has spent his life studying. Life, of course, includes human beings—you and I. If Dawkins is right, why should he study living things, or why should we? What is the purpose of using our purposeless lives to study purposeless things? Perhaps Dawkins has found his purpose in theology as he endeavors to convince everyone that there is no God.

As we think about this, we have to be amazed at how incredibly ironic the Dawkins delusion is. In the meantime, we will continue to admire the design we see in the world and pay homage to the Designer. Faced with the Dawkins challenge that design is an illusion, we choose to believe our eyes–and our common sense.

Justifying Animal Behavior in Humans

Bonobos - Justifying Animal Behavior in Humans
We have received several letters from people suggesting that sexual practices among animals show that humans are not unique in their moral choices but are merely acting out their animal heritage. Our supposed animal heritage can then be used for justifying animal behavior in humans.

We have read articles and news releases describing animal behavior including the pedophilia practices of bonobo apes, and recreational sex, rape, and homosexuality in monkeys. We have seen documentaries on the fact that many males in the animal kingdom kill the babies of their own species. The supposed reason for that is to push the mothers of those babies to become more quickly receptive to the sexual advances of the males.

It is a foolish argument to suggest that humans are just animals and that all human behavior is inherited and therefore we can’t condemn it. One PBS program recently said that the greatest threat to the babies of bears and lions was from the males of their own species. I am sure that very few atheists would maintain that human males should not be condemned for killing their offspring.

The other major point we would make is that sexual activity in animals is almost always a way of expressing dominance and control. The pedophilia practices of the bonobos produce extreme violence among the clan. Using sex to show dominance or to establish a pecking order among the group is a long way from the purpose of human homosexuality.

God created humans in His image. That means that dominance and control is not the only focus of our relationships. The “oneness” that God intended for sexual relationships (Genesis 2:24) is a long way from establishing who is going to control the group in which they live. The “agape” love which humans are capable of, goes far beyond sex. In John 17:24-26 Jesus spells out agape in terms of God’s love for His son. Animals are not capable of that kind of love.

When humans misuse sex or use sex only for physical pleasure, the result is always catastrophic. After Amnon raped Tamar (see 2 Samuel 13) he “hated her exceedingly.” That was the beginning of a long series of tragedies for the whole family. Justifying animal behavior in humans violates the uniqueness of humans and human relationships, just as it did for both Tamar and Amnon. Animal sexual activity does not produce what God intended in the marriage relationship.

How Many Moons Are Enough?

How Many Moons Are Enough?
When it comes to moons, it seems that Earth got cheated. We have only one moon while Mars has two. Neptune has fourteen moons. Uranus has twenty-seven. Saturn not only has rings, but it also has sixty-two moons. (Update- We now know that Saturn has 82 moons! Lucky Jupiter has sixty-seven! (Update- It’s now 79!) To add to the embarrassment, puny little Pluto, which is no longer considered a planet, has five times as many moons as Earth has! The only bragging point we have is that we can say we have more moons than Mercury and Venus. (They have none.) So how many moons are enough?

Actually, one works very nicely. Our single moon is critical to the existence of life on Earth. It’s because of the moon that Earth has a stable tilt on its axis of 23.5 degrees. That tilt prevents temperature extremes on this planet. With no inclination, the area of the Equator would be extremely hot and the poles extremely cold and dark all year. With a greater tilt, seasonal weather changes would be extreme all over the planet. Because of the angle of the inclination, we have proper seasons, and the air gets mixed to temper the weather extremes.

Our moon has the right mass at the right distance to keep Earth’s tilt stable. The moon plays several crucial roles in making our planet a great place to live, but stabilizing the tilt is one that’s extremely important. So how many moons are enough? I would say that one moon of the right size and at the right distance is just right.

Oh, and those other planets with more moons — none of them are habitable. Guess who has bragging rights now? Thank God that he gave us a just-right moon, and we don’t need any more. We see evidence of God’s design in every detail of our planet.

Galactic Coincidences?


On a clear, moonless night, you can look up and see the Milky Way. Actually, we are in the Milky Way, a spiral galaxy of 200 billion stars one of which is our Sun. We are located in a spiral arm of that galaxy 26,000 light-years from its center. Our location seems to indicate many galactic coincidences.

At the center of the Milky Way (and perhaps all galaxies), there’s a black hole sending out lethal radiation to a distance of 20,000 light-years. Farther out than 26,000 light-years from the center, heavy elements that are vital to our existence and survival are scarce. We are in what astronomers call the “galactic habitable zone.”

Spiral galaxies rotate, and we are near the co-rotation spot where our solar system moves at almost the same rate as the spiral arm we are in. If we were in precisely the co-rotation spot, we would experience gravitational “kicks” which could send us out of the habitable zone. If we were far away from the co-rotation spot, we would fall out of the arm and be subjected to deadly radiation.

In the vast majority of spiral galaxies, the habitable zone and co-rotation spot do not overlap. Most other spiral galaxies are not as stable as ours. Most galaxies are not spiral galaxies and would not have a stable location for advanced life.

Furthermore, galaxies exist in clusters, and our cluster called the “Local Group” has fewer, smaller, and more spread-out galaxies than nearly all other clusters. Most galaxies are in dense clusters with giant or supergiant galaxies which create deadly radiation and gravitational distortion making advanced life impossible.

These are only a few of the many factors that “just happen to be” true of the place where we live. Are these just galactic coincidences? Some say it’s all accidental. We say it’s a grand design by a Master Designer. The next time you look up at the Milky Way, thank God that we are precisely where we are.

Lights of the Seasons

Lights of the Seasons
Genesis 1:14 says that God allowed the “lights in the expanse of the sky to separate the day from the night” and to serve as “signs to mark seasons and days and years.” We can call them the lights of the seasons.

Although light is essential for our existence, the Sun, Moon, and stars are intended to serve an additional purpose. In Genesis 1:1 God created the heavens and the Earth. “Heavens,” or “shamayim” in the original Hebrew, would include the Sun, Moon, and stars. Genesis 1:14 tells us that God lifted the cloud cover (described in Genesis 1:2 and Job 38:9) so that the heavenly lights could be clearly seen to establish the circadian rhythm, give us a way to determine directions, and allow us to mark the passage of time.

Today (December 21) is the time when the Sun reaches its lowest point in the sky. In the Northern Hemisphere, it is the shortest daylight and marks the first day of winter. In the Southern Hemisphere, it is the most extended daylight which marks the first day of summer. We call it the winter or summer solstice. The word “solstice” comes from two Latin words meaning “sun” and “stand still” because on this day the Sun appears to momentarily stop its southward journey and start back toward the north. (The opposite is true on June 21.)

When Earth has made one complete rotation on its axis, the Sun’s position shows us that one day of 24 hours has passed. When the Earth completes one revolution around the Sun (approximately 365 days), we can see that the Sun has finished one cycle of its apparent north-south swing. We know that one year has passed.

It’s the 23.4-degree tilt of Earth’s axis with respect to the Sun that causes us to have seasons as our planet makes its year-long solar revolution. That tilt makes it appear that the Sun is moving north and south through the sky each year and gives us seasons. Without seasons, only limited areas of Earth would be habitable. Without day and night, one half of the Earth would be baking in the sunshine while the other half would be continually cold and dark. When the Moon has made one revolution around Earth, we can see that it has completed all of its phases and we know that one lunar (or synodic) month has passed.

As we consider these lights of the seasons, keep one thing in mind. When Moses recorded the words of Genesis, people didn’t understand what caused “seasons, days, and years.” Now we do. We can see the full meaning of Genesis 1:14 when God opened the sky to reveal the lights of the seasons. Moses accurately recorded what God revealed to him, but he didn’t understand it. Science allows us to know how God did what He did. We believe that is what science is all about – discovering how God did it. True science and a correct understanding of the Bible are in complete agreement because God is the author of both.

Human Gene Editing

Human Gene Editing
We have written about human gene editing using the technique known as CRISPR. (Read more about it HERE and HERE.) One of the fears of those who are opposed to uncontrolled use of the CRISPR technique is that it will be used to produce “made to order” babies.

CRISPR could be used to treat a person with a genetic disease, but that is a different scenario from controlling a baby’s athletic skills or eye color. The big problem is that once we apply human gene editing, whatever was changed is passed on to future generations. That includes whatever errors might be made in the process.

He Jiankui, a Chinese scientist, announced in early December 2018, that he had altered the DNA of two embryos to make them resistant to HIV. He then placed them in their mother’s womb resulting in a successful live birth. Marc Thiessen writing in the Washington Post said, “Gene editing is here, and it poses an enormous threat to humanity.” The problem is that there is no way of telling what other characteristics were altered in the process, or what it could lead to. Thiessen says “If science continues down this road, we will cross a moral line from which there may be no return.”

Science cannot determine the use to which its discoveries, such as human gene editing, will be applied. Will CRISPR be used to eliminate diseases that are produced by genetic change? On the other hand, will it become a way for scientists like Jiankui to make large amounts of money by producing made-to-order babies? The belief system of the scientists is what will determine this. An atheist has no reason not to use CRISPR to make a fortune for himself no matter what it does to the human race.

We need Christians who believe God is our Creator. We need scientists and medical practitioners who accept God’s view of humans that we are special, created in His image and the dwelling place of the Holy Spirit. (See 1 Corinthians 3:16.)

Life Expectancy and Despair

Life Expectancy and Despair
The Centers for Disease Control and Prevention has just released its latest annual report on American life expectancy. The report shows that for the third year life expectancy in the United States has not grown and has declined. The last time that this happened was in World War I when a flu pandemic killed 675,000 people.

The report says that drugs and suicide are the main culprits now with the overdose rate up 356% since 1999. The 2017 death toll is 70,237 far outstripping the total American fatalities in Vietnam.

It is interesting that everyone studying this life expectancy issue seems to agree on what the cause is, and what the solution is. The NationalReview.com says that “we are facing not so much a drug problem as a heartbreak problem.” An AARP study found that one-third of Americans report chronic loneliness and conclude that isolation is a state “about as deadly as smoking.” David Brooks writing in the New York Times says “It’s not jobs, jobs, jobs or better welfare programs that will save us from this ongoing social catastrophe; it’s human relationships and a society that cares about people more than money.”

We suggest that people need to read and follow the example in Acts 2:41-47. People had a common faith in God, and they took care of each other. They “CONTINUED DAILY WITH ONE ACCORD” and spent time together focusing on meaningful relationships. The result was that “they had favor with all the people.”

This reminds me of a comment I heard Carl Sandburg make when someone asked him what he thought about Christianity. His response was “I don’t know, I have never seen it tried.” Christianity is not a legalistic way of restricting human behavior. It is a way of life that blesses everyone who is a part of it and everyone around those who live it.

Moon Causes Tides

Moon Causes Tides
Most people know that the Moon causes tides. The gravitational pull of the Moon mostly causes the ocean tides. The tides are essential for cleaning the coastlines and estuaries.

On average, the Moon is 238,900 miles (384,470 km) from Earth. What if the Moon were only half of its present distance from Earth? The Moon half as far away from Earth would create ocean tides eight times higher than they are now. At one-fourth the current distance from Earth, the tides would be sixty-four times higher than they are today. Imagine a world with tides like that! Coastal cities around the world would be in danger. Coastal lowlands would be uninhabitable. The coasts would be eroded away in a short time. Upflowing tidal waters would overpower rivers that flow into the oceans. Floodplains along the rivers would fill and drain with each ebb and flow of the tide.

With a closer Moon, all kinds of aquatic creatures living along the shore would not survive the destructive forces of the tides. In addition to those catastrophes, seawater would deposit salt on the fertile land along the rivers making them barren. Glaciers along the coast of Alaska and Greenland and the Ross Ice Shelf in Antarctica would be broken up. Icebergs would clog the Atlantic Ocean. Icebergs would sometimes wash ashore with the tides in places far from the cold climates, crushing whatever was in the way.

It all sounds like a plot for a science fiction movie! So the Moon causes tides, but don’t worry. The Moon is not going to move closer to Earth. We can be thankful that it’s is precisely the size and location where it is. It seems as if Someone designed it that way for a purpose.
