We Could Not Survive Without Bacteria

We usually think of bacteria as agents of infectious disease–“germs.” However, many types of bacteria are helpful to us. The truth is, we could not survive without bacteria.

More bacterial cells are living on and in your body than there are human cells in your body. Your body has more bacterial cells than there are people in the whole world! Even more amazing, the total biomass of all bacteria in the world is greater than that of all plants and animals in the world!

Bacteria in our digestive system allow us to digest the food we eat. Good bacteria even help us fight off their less-friendly cousins. Researchers recently discovered that a human skin bacteria (Staphylococcus epidermidis) protects against skin cancer. Those bacteria produce a compound nicknamed 6-HAP, which stops DNA formation in cancer cells, but not in healthy cells. The researchers hope to use this information to develop new treatments for skin cancer.

Bacteria live everywhere in soil, water, hot springs, the deepest part of the oceans, deep in the Earth’s crust, and even in radioactive waste. Bacteria break down waste materials, including sewage and oil spills, to help keep our world clean. Industry uses bacteria to produce cheese, yogurt, ethanol, vitamins, antibiotics, and prescription drugs.

Before humans or any form of animal life could live on the Earth, there had to be a full complement of the right kinds of bacteria. An intricate system of checks and balances had to exist for things to stay in a favorable condition. We have often paid the price for upsetting the balance of the microscopic world.

Don’t forget that we could not survive without bacteria. They feed us, clean up after us, and even fight the diseases some of their cousins cause. They also show us the wisdom and intelligence of the Creator who made us, and those microbes we can’t see.

Stink Bugs and Human Mistakes

Brown marmorated stink bugs (Halyomorpha halys) have become a significant pest in areas of the United States. They are native to Asia, but humans accidentally introduced them into the USA in 1998. Since they have no natural predators in North America, their numbers have grown dramatically. We can learn a lesson from stink bugs and human mistakes.

Brown marmorated stink bugs are commonly known to Americans simply as “stink bugs.” The “stink” is because they give off a foul smell when disturbed. “Marmorated” refers to their marbled coloration. You can distinguish brown marmorated stink bugs from similar-looking beetles by the alternating light and dark colors on their antennae and the edges of their abdomen.

When the weather turns cold, these pests find ways to get into homes through small openings, and there they hibernate. Sometimes the heat in the house causes them to become active and annoy the residents during the cold months. The real problem arises when warm weather arrives. That’s when they come out in force.

Halyomorpha halys is a major agricultural problem in some areas because they feed on a wide variety of fruit and vegetable crops. They pierce the plants or the fruits with their needle-like beaks and suck out the fluids. At the same time, they inject saliva, which causes shriveling and rotting.

In their native countries, there is a wasp that feeds on these stink bugs. The US Department of Agriculture has looked into importing those wasps into the United States to bring the bugs under control. The problem with that idea is the wasps might become new pests because they don’t have native predators. Traps remove only some of the bugs, and pesticides can have harmful side-effects. Pesticides are also not very effective because they stay on plant surfaces. The stink bugs don’t eat the surface of the plants. They pierce through the surface and drink the juices from inside. Perhaps the best hope, for now, is that some of our native birds and insects start to develop a taste for stink bugs as their population increases.

The Creator has given us an excellent and well-balanced system, but we humans have a knack for ruining God’s gifts. That has been true from the Garden of Eden until today. We see a connection between stink bugs and human mistakes.

Pollination of an African Lily

Various types of plants are pollinated by bees, butterflies, hummingbirds, or bats. Non-flying mammals pollinate some plants. Rodents accomplish pollination of an African lily (Massonia depressa) that grows in a desert region of South Africa and Namibia.

Massonia depressa forms two huge leaves lying flat on the ground. Its flower in the center is at ground level within reach of the gerbils which pollinate it. Each evening the plant secretes globs of nectar as thick as jelly. The strong yeast-like scent attracts hairy-footed and short-eared gerbils that come at night to eat the nectar. The gerbils get covered with pollen as they spread the flowers open with their front legs and push their faces into the nectar.

Although the nectar is sugar (sucrose) jelly, it is 400 times as thick or viscous as an equivalent sugar solution. Rodents are the pollinators because the nectar is too thick for insects to drink. The gerbils lap it with their tongues. To accommodate the mammal pollinators, the flowers must be more sturdy and produce more pollen than plants pollinated by insects. Unlike the brightly colored flowers that attract flying pollinators in the daytime, these flowers are dull. The Massonia depressa produces seeds that are light enough that the wind scatters them.

We see evidence of design in the pollination of an African lily. This plant depends on a gerbil for reproduction, and the rodent depends on the plant for food. They need each other to survive. The plant is on the ground where the animal can easily reach it. It produces a fragrance and jelly to attract and feed the animal. Insects can’t eat the food or pollinate the plant. The lily and the rodent seem to be made for each other. Some suggest they evolved together by coincidence. We suggest this is another project by the Master Designer.

No Substitute for Mothers

There is no substitute for mothers. At least that’s how it now stands under British law, and that’s the way God intended. Even a biological woman who identifies as a transgender man is still a “mother” and not a “father.”

Freddy McConnell is the current name of a British transgender journalist who was born as a female. She had a mastectomy and testosterone treatments and now identifies as a man. Freddy became pregnant by sperm donation, gave birth to a baby, and wanted to be listed as the “father” on the birth certificate. The High Court of Justice in London said, “No.” Freddy took the case to the Court of Appeal, and at the end of April 2020, the justices agreed with the High Court.

The British Children Act of 1989 requires that a mother be listed on the birth certificate. The justices said that according to the law, “a mother has automatic parental responsibility for a child from the moment of birth.” Further, they stated: “No-one else has that automatic parental responsibility…The fact of giving birth to a child has that effect as a matter of operation of law…From the moment of birth, someone must have parental responsibility for a newly born child…” In other words, there is no substitute for mothers.

Judge McFarlane of the High Court of Justice said: “It is now medically and legally possible for an individual, whose gender is recognized in law as male, to become pregnant and give birth to their child. Whilst that person’s gender is ‘male,’ their parental status, which derives from their biological role in giving birth, is that of ‘mother.’”

There is great confusion in society today concerning sexual orientation, genders, and gender roles. Recently I was required to complete a form that listed seven different options for “gender.”

I thank God that there are biological women who are willing to fill the role of being mothers. Women were designed for that role, and there is no substitute for mothers. For various reasons, many women today are single moms, and here are single fathers who must serve as “Mr. Mom.” The truth is that women can do many jobs as well as men, but no man can fill the full role as a mother. Today we want to thank and honor our mothers, especially Christian mothers, for filling that essential role.

Communist Chinese Priority

While the world is trying to stamp out a contagious virus that originated from China, the Chinese Communist government is battling something else. The Communist Chinese priority is to stamp out Christianity.

In March, the Chinese government went on a campaign to remove crosses from churches in three eastern provinces. They brought in cranes to lift the crosses off the church steeples because, they said, religious symbols cannot be physically higher than the Chinese national flag. Government officials told the church leaders that the crosses “were too eye-catching” and might “attract people into the churches.”

Lincoln Christian University in Lincoln, Illinois, has a Chinese Institute. The director, Jian Zhu, said that China’s persecution of house churches has intensified. Chinese authorities ask people to spy on their neighbors and report churches meeting in homes. They also require teachers and students to sign statements denouncing Christianity.

Zhu said, “Cameras are all over to watch church and Christians go to Sunday services.” What do the Communists do with the data they gather concerning Christians? According to Zhu, they threaten families not to go to church, “or they will be punished or their relatives could be in trouble.”

As those of us in the United States are prevented from meeting together because of a virus, remember the Chinese Christians. The virus will soon be controlled, but the Communist Chinese priority to persecute Christians will probably only get worse.

Positive Results from a Quarantined Easter

Today is a historic Resurrection Sunday when church congregations in the United States and much of the world are unable to assemble in one place. We pray that we will be able to get back together soon and that this will never happen again. However, there may be some positive results from a quarantined Easter.

In some countries, Christians meet in fear for their lives and physical well-being, not because of a virus, but because of the government. In the United States, we have never experienced that kind of persecution. Perhaps the present experience will give us a little more appreciation for the freedom we have. In the early days of the Church, persecution was common. Despite that, the Church grew.

Perhaps one of the positive results from a quarantined Easter is that we will think less about the commercialism of the day and concentrate on the real meaning. Instead of Easter trappings, we can spend more time contemplating Christ’s resurrection and what it means. Instead of Easter Sunday, we can think of it as Resurrection Sunday.

We can be thankful for modern electronic communication that allows us to stay in contact with fellow Christians as well as family and friends. Thanks to the internet, many churches are continuing their services while “social distancing.” In doing so, they are reaching and sharing the gospel with people who would never come to their building. Perhaps this will encourage us to use the internet to spread the gospel in more effective ways than ever. That could be another one of the positive results from a quarantined Easter.

Another positive result might be that it will help us appreciate the value of fellowship with other Christians. The Church not being able to meet in person can help us realize what a blessing it is to worship with our brothers and sisters. I hope that when we can get back together, we will appreciate the fellowship of other Christians as never before. Perhaps when this problem is over, we will find a new enthusiasm for “Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as you see the day approaching” (Hebrews 10:25).

The truth is that Resurrection Sunday should not be a once-a-year event. Each week is a celebration of Christ’s resurrection. We encourage you to read our previous posts titled “Christ’s Resurrection Celebration” and “The Event that Changed the World.”

Real Death Rate is One Per Person

As the world and our country battle the coronavirus that causes COVID-19, we see daily statistics on the death rate. Whatever the death rate from COVID-19, as someone has said, the real death rate is one per person.

Death is something we generally don’t like to talk about or even think about. Some people seem to believe that if they don’t think about it, they won’t die. That hasn’t worked for anyone so far. Failing to think about death leaves us unprepared when it happens. In his book Risen Indeed: Making Sense of the Resurrection, Stephen T. Davis wrote that “Human beings are the only animals who know that they must die, and thus the only animals who try to hide from themselves the fact that they must die.”

One of the things that separates us from other animals is our reasoning power. Our reason tells us that it is irrational to believe that impersonal and nonrational forces could have produced us human creatures who are both personal and rational. In my opinion, that is one of the strongest evidences for a personal and rational Creator God.

Now, suppose that you were the Creator of the universe, and your crowning creative achievement rebelled against you. Would you be willing to take on the form of those rebellious creatures to redeem them? Would you be willing to leave your eternal abode to enter the world of those disobedient and ungrateful beings to show them how to live? Would you be ready to die for them, even though they still didn’t catch on and follow your instructions? Is it possible that the Creator could have that much love?

It is more than just possible. It happened. The Creator did it. He died for us—for you and me! But that isn’t the end of the story. He conquered death! Yes, you can say that the real death rate is one per person in this life. But just wait for what God has in store for those who love him! (Read 1 Corinthians 2:9.)

Spring Arrived in the Northern Hemisphere!

Just a few hours ago (11:49 p.m. EDT March 19 or 0349 GMT March 20, 2020) spring arrived in the Northern Hemisphere. Officially it is spring, even though it may not feel like it where you live.

For the next three months, the days will continue to get longer as the Sun moves farther north. This year, the Sun reaches its greatest northern latitude on June 20 when it will be at its highest elevation in the Northern Hemisphere sky. In the Southern Hemisphere, it will be at its lowest elevation. The autumn equinox will arrive on September 22. Then, on December 21, the Southern Hemisphere will have the Sun directly overhead at 23 degrees south latitude while it will be at the lowest point in the north.

At Chichen Itza on the Yucatan Penninsula of Mexico, the Mayans built a huge pyramid to a serpent deity around A.D. 1000. They engineered the pyramid so that at the spring equinox, the Sun’s light resembles a huge snake slithering down the steps on the structure’s face. The Mayans called the equinox “the return of the Sun Serpent.” They recognized the reliable and consistent seasons that make life possible. They could not comprehend everything required to create that consistent reliability. They didn’t know the God who created all things.

What does it mean that spring arrived in the Northern Hemisphere? It means that God has designed the Earth and our solar system to be predictable. He located our planet the just-right distance from a just-right star (our Sun). He gave Earth’s axis a just-right tilt relative to our just-right orbit around the Sun to create the seasons. The result, as we wrote yesterday, is that we have a planet suitable not just for life, but for advanced life.

Scientists today use SETI to search for intelligent life elsewhere in the universe. They use telescopes and space probes to look for an exoplanet suitable for life. So far, after millions of hours and unknown amounts of money spent searching for alien life, the results have been zero.

Whether life exists anywhere else in the cosmos makes no difference for the existence of God. As spring arrived in the Northern Hemisphere, it reminds us that life exists here. As we see life blossoming all around us, we are reminded that every human life is precious God. He put us here for a purpose.

Vernal Equinox Arrives Today

The orbit of the Earth around the Sun produces variations in the seasons with four orbital positions having particular significance. Today, March 19, 2020, the Sun will pass directly overhead at the equator. The exact time will be 11:49 p.m. EDT (0349 GMT March 20, 2020). We can rejoice that the vernal equinox arrives today!

This is the earliest equinox in the United States in 124 years! As you can see in the diagram, the usual date for the vernal equinox is March 20 or 21, depending on where you live on the Earth. The reason it arrives on the 19th this year in North America is somewhat complicated, but it has to do with leap years and daylight saving time. We won’t get into that, but I thought we should explain why the diagram differs from this year’s dates.

There is wonderful history of how the Greek scholar Eratosthenes of Alexandria used the equinox to measure the circumference of the Earth. He knew that on the equinox, a pole stuck vertically in the ground left little or no shadow at noon, depending on location. He compared the length of the shadow of a pole in Syene, a town in southern Egypt, with one in Alexandria in northern Egypt. Using the difference in the shadow lengths, he calculated the circumference of the Earth. His calculation was very close to the known circumference today, and it proved the Earth was round. He did that in 245 BC, long before Columbus sailed.

The four polar positions roughly predict the seasons that have been used by every culture to control planting, harvesting, and preparing the soil. In Genesis 1:14, God said, “Let there be lights in the expanse of space to divide the day from the night, and let them be for signs, and for seasons, and for days, and years.” God not only instituted day and night, but He also positioned the Sun and Moon so they could be used to mark the seasons we would need to live on this planet.

As the vernal equinox arrives today, we wish you a happy equinox!! Enjoy the season and the official end of winter in the Northern Hemisphere. We will have more on the spring equinox tomorrow.

Churches of Christ Disaster Relief

In the early morning of Tuesday, March 3, 2020, an EF-4 tornado did devastating damage to the city of Cookeville, Tennessee. On the same night, several lesser tornados swept across middle Tennessee, including Nashville. We have discussed before the question of, “Where is God when disaster strikes?” That is where Churches of Christ Disaster Relief is involved.

When a need arises, God works through His people. One of the buildings that survived the hit was the one where the Jefferson Avenue Church of Christ meets in Cookeville. Within hours, their gymnasium became a relief center. Churches of Christ Disaster Relief Effort, Inc., with headquarters in Nashville, brought in truckloads of needed supplies for the hundreds of people who had lost their homes. Members of the Jefferson Avenue church came in to assist, even though they had also been affected by the storm. Area schools were closed, so teens, as well as others, showed up to help.

Before this tragedy happened, Rick Gilbert, deacon who serves as the church’s disaster relief coordinator, had taken groups of church members to Nashville to pack supplies for Churches of Christ Disaster Relief. Now they had a chance to see where those boxes go and how much they are needed. He said, “Now we see why we did what we did.”

On March 6, President Trump visited Cookeville, and Gilbert guided him on a tour of the relief center set up by the church. Gilbert said of the President, “He was touched. He was really touched.” President Trump was in the relief center for about 45 minutes, talking with people and even praying with them. The President said, “Even all of this—Churches of Christ—tremendous amounts of food and goods, and it all came within a matter of hours. So it’s a case study—a case study of what should be done and how it can be done. It’s Tennessee.”

More than that, Mr. President, it’s Christianity—God’s people following the example of Jesus.
