David and Goliath – Fact or Myth

David and Goliath – Fact or Myth - Sling with 5 Smooth Stones

Skeptics frequently take a historical biblical story and attempt to show that it is impossible. Some religious folks have answered these challenges by saying the event is a miracle of God and thus is not open for discussion. The Bible certainly describes miracles of God that can’t be explained by natural causes and are therefore not available for investigation. For example, we can’t prove that Jesus raised Lazarus from the dead by scientific evidence because we were not there and can’t go back in time. If a person doesn’t believe in God, then a biblical record will certainly not convince them and may encourage them to reject the Bible as a bunch of fairy tales. In the case of David and Goliath, however, the evidence is strong that the account is credible.

Several years ago, I had an American Field Service student from South America in my physics class at Riley High School. When our class was studying centrifugal force and circular motion, he offered to show us what he called a “shepherd sling.” This was a pouch with a long cord attached at each end made from some non-stretchable material. One of the cords had a loop at the end of it, and the other cord was straight.

My student put a golf ball in the pouch and swirled the pouch and ball around his head, holding the two cords in his hand, the one with the loop wrapped around his finger. He got the ball/pouch going at a very high speed and then released the straight end of the cord, sending the golf ball flying at an incredible speed. Taking this outside, he could knock a tin can off a post at 100 feet. The force of the strike was so strong that the can flew a considerable distance. From 100 feet, this student could put a rock through a thick board.

Biblical Archaeology Review
published an article examining the statistics for the encounter of David and Goliath
. Archaeologists have discovered reliefs in the mortuary temple of Ramesses III showing Egyptian slingers defending a ship. An Assyrian relief from Nineveh celebrating Sennacherib’s military victories shows Assyrian slingers in 701 B.C. whirling stones toward Judahite defenders atop the walls at Lachish. Archaeologists have found the remains of slings and the stones used in them.

These ancient slings had military uses up to 400 yards, and Roman slingers used them at distances of 200 yards. Arabian slingers hunt game at 30 to 50 yards today, and a moderately skilled slinger can achieve up to 113 miles per hour. Goliath had a javelin that he could throw 20 to 30 yards, meaning that David’s sling was vastly superior with about twice the range.

God certainly facilitated the actions of David, but the story of David and Goliath has historical validity, indicating that it was not miraculous and not a myth.

Foods Derived from Flowers Need Auxin

Foods Derived from Flowers Need Auxin
Strawberries – the only fruit with seeds on the outside

What seems like a simple question may have a very complex and essential answer. The question is this: How does a flowering plant develop fruits and seeds? This is a crucial question to answer for the production of common food crops such as peanuts, corn, rice, strawberries, and all other foods derived from flowers.

The time when flowers turn some of their parts into seeds or fruit determines when the fruit will be ready to harvest, how big it will be, and what nutrients and water must be applied at what time.

Zhongchi Liu at the University of Maryland has identified a gene called AGL62 that stimulates plant production of a growth hormone called “auxin.” Once the gene activates, the plant synthesizes auxin, causing the creation of a seedcoat. The seedcoat is the outer layer protecting the endosperm, the part of a seed that provides food for a developing plant embryo and fruit. More auxin can boost grain size and stimulate fruit enlargement. If there is insufficient auxin, the crop produced will be smaller, and the fruit will not be commercially viable.

Liu has been working with strawberries because they are easier to study, but it applies to virtually all foods derived from flowers. This is another example of the design God built into the creation of life. When humans finally understand the design, it opens up a way to produce more food for a hungry world.

Invasive Species and Environmental Problems

Invasive Species and Environmental Problems - Lionfish
Red Lionfish

It is interesting to hear skeptics blaming God for the existence of invasive plants and animals. There is no question that non-native species thrive in the United States. However, some species brought to this country have no natural predators to keep them in check. As a result, they cause crop damage, human health problems, and environmental damage. There are nearly 6,500 invasive species in America, and they cause more damage every year than all natural disasters combined. The stories of how they got here are interesting. Here are some examples:

NUTRIA – Also known as coypu or “swamp rats,” these South American rodents were brought to America by fur farmers in the 20th century.
BROWN GARDEN SNAIL – These mollusks were brought to California as food by French immigrants in the 1850s.
KUDZU – This Asian vine was brought to the U.S. as an ornamental plant in 1876, and farmers used it to feed livestock and reduce soil erosion. To make kudzu widely available to farmers, government agencies provided 85 million seedlings.
WILD BOAR – These animals were native to Eurasia and brought to the U.S. in the early 1900s for hunting. Early settlers in the 1500s introduced domestic pigs as a food source. Unfortunately, some escaped pigs mated with the boars resulting in the invasive species we have today.
LIONFISH – These beautiful fish with venomous spines are natives of the South Pacific and Indian oceans. Aquarium enthusiasts brought them to the U.S. between 1985 and 1992, but when released, they wipe out native fish populations.
DANDELION – Early European settlers brought these “weeds” to the U.S. for food and medicinal purposes.

These invasive species and others cause billions of dollars in economic damage annually. However, we should understand that not all non-native species are considered invasive. For example, corn and wheat are not native to the United States but were brought here as successful food crops.

In Genesis 9:3, God told Noah, “Everything that moves shall be food for you, just as I have given you green plants.” God has given us a wide variety of food sources designed to thrive in various ecological environments, but we must be good stewards of how we use and spread them.

Problems arise when people purposely or accidentally transport plants or animals to new locations where they become out of control. Without predators to control populations, they can throw an entire environment out of balance. Most of our environmental problems are human-caused, and invasive species of plants and animals are good examples.

Structural Color in Plants

Structural Color in Plants - Viburnum tinus
Viburnum tinus berries

When you see a peacock with brilliant green in its feathers, realize that it has no green feathers. Its feathers are actually brown, but God has used a clever optical trick to make them look green to us. We call it structural color. Likewise, many butterflies have bright blue spots on their wings, but there are no blue pigments in a butterfly’s wings. 

Some plants produce fruits that look blue to us without having any blue pigment in the fruits. The only plants known to produce blue fruits in this way are Viburnum tinus and Lantana strigocamara. You will not get a blue stain if you crush their berries in your fingers. On the other hand, if you crush a common blueberry, its blue pigments will stain your fingers.

When you see a blue pigment, it is blue because it absorbs all other colors while reflecting blue. Structural color uses microscopic pyramid-like structures that manipulate the light. Since blue light has higher energy than other colors, it escapes the structure. Structural color requires no pigments, and you might call it an optical illusion.

Color is essential in the natural world. For example, animals with color vision use colors to camouflage, attract others, or discern whether something is good to eat. The problem with using pigments to produce color is that the chemistry to get a particular color is quite complex, but structural color does not involve any chemistry. 

People have used chemicals to produce the colors we see in our fabrics, but some colors can be costly and time-consuming to produce. God has created a chemical-free method to produce much of the beauty we see in the world around us. Beauty in structural color gives evidence of a wise Creator.

Chemical and Medical Side Effects

Chemical and Medical Side Effects

We live in a time of incredible advances in chemistry and medicine. However, we face the problem of chemical and medical side effects from modern drugs and food additives. Therefore, a medication designed to address one problem will often create other unexpected issues. I can give personal testimony to that.

I have blood pressure issues that are hereditary and a product of my age. For two years, doctors tried various medications to lower my blood pressure, but nothing worked. Finally, a doctor found a new drug that does work. My hypertension is under control, and I am thankful for that. This new drug, in conjunction with some previous medications, together with my new regime of exercise and eating habits, has greatly reduced my risk for a stroke.

The problem with this new medication is that it has side effects that were unknown when I started taking it. It affects my vision, balance, breathing, and sleep. When I complained to my doctor, who likes to be a comedian, he said, “Well do you want to die of a stroke or the side effects?”


We also have chemical and medical side effects from food additives and drinks. People in Christ’s day used fermented grape juice because the water was unsafe to drink. The “wine” available then had a very low percentage of alcohol, around 4%. Today, distillation processes allow the alcohol percentage to be vastly higher, and alcohol poisoning is a significant issue. Recently in Missouri, 19-year-old Daniel Santulli suffered severe brain damage after being forced to drink alcohol as part of hazing during a pledge reveal party for the Phi Gamma Delta fraternity. When I was a fraternity pledge at Indiana University, my fellow pledges were forced to drink alcohol until they could no longer walk. Then they were then driven to a remote country road and dropped off.

Now the college drug of choice is marijuana. Modern marijuana has levels of THC (the drug responsible for psychoactive effects) 15% higher than in the 1970s. British studies show that these high THC levels increase the probability of addiction. We are now seeing fatal accidents caused by marijuana, as Newsweek reports that car accident rates have risen in states after legalizing marijuana sales. Science has not adequately studied the long-term side effects of marijuana.

In addition to drugs, people use food additives and supplements without scientific studies exploring their long-term side effects. God has given us plants and substances such as alcohol that we can use to alleviate human suffering. However, chemical and medical side effects are likely to increase suffering when we use them as untested recreational drugs or food additives.

Nadir Asteroid Impact Crater

Chicxulub and Nadir Asteroid Impact

One of the challenges to evolutionary theory is the principle of uniformitarianism–the assumption that no process has ever functioned on Earth that is not going on today. We are not talking about common disasters but events in Earth’s history that would have altered the course of evolution or stopped it entirely. For many years, scientists have known about the Chicxulub asteroid that struck the area that is now Mexico’s Yucatan Peninsula, probably causing the extinction of the dinosaurs. Such an event would have changed life’s future direction. Now, there is news of a Nadir asteroid impact crater.

BBC news reported that geologists discovered a possible asteroid crater off the coast of Guinea in west Africa. They call it the Nadir crater because it is at the Nadir (opposite lowest point) of the Chicxulub crater. This new crater is 8,500 meters wide and over 300 meters lower than the seabed. It is about the same age as Chicxulub but much smaller. The Chicxulub crater, caused by a larger asteroid, is 12,000 meters wide.

Both of these asteroid collisions would have violated uniformitarianism, dramatically affecting life on Earth. The Chicxulub asteroid impact would have caused major earthquakes, tsunamis, and a global firestorm. The result would have thrown enough dust into the atmosphere to plunge Earth into a deep freeze that dinosaurs could not have survived.

Since the Nadir asteroid impact crater is in an ocean environment, it would have caused a tsunami with a wall of water over 1000 meters high. The Nadir collision would have produced about 1,000 times more energy than Tonga’s recent (January 2022) volcano eruption. However, the energy from the Chicxulub impact would have been about 10 million times greater.

The textbook model of evolution is greatly simplified. We don’t fully understand how an asteroid collision would have affected life on Earth. It seems unlikely that most life forms could have survived the one-two punch of Chicxulub and Nadir asteroid impacts.

Genesis 1:1-3 indicates that there was a change in the Earth. An accurate translation of verse 2 is that Earth “became empty and wasted.” That is precisely what the asteroid collisions would have caused. This may have been God’s methodology of a final step to make Earth fit for human life. This new evidence supports the biblical account in ways we are only beginning to understand.

Labor Day in the United States

Labor Day in the United States

Today is Labor Day in the United States. Looking back, we can learn from the COVID infestation and the consequences of the isolation it brought to most of us. Those who keep records of such things tell us that in two years of the pandemic, there was a massive increase in divorce, pornography use, drug use and overdoses, and a 39% increase in alcoholism. In my experience, people who retire from their job to the idleness of a rocking chair don’t live very long. When my wife died, I was able to survive the loss by spending 90% of my time in work connected with this ministry.

To students of the Bible, all of this is no surprise. In Genesis 3:19, God told Adam, “By the sweat of your brow, you will eat your food.” The law of Moses was centered around labor – “Six days you shall labor and do all your work” (Exodus 20:9). The inspired Bible writers talked about the fact that work is good for humans physically, mentally, and spiritually. Consider these verses:

Ecclesiastes 5:12 “The sleep of a laboring man is sweet, whether he eats little or much, but the abundance of the rich man will not allow him to sleep.”
Proverbs 6:6 “Go to the ant, you sluggard, consider her ways and be wise.”
Proverbs 14:23 “All hard work brings profit, but mere talk leads to poverty.”
Proverbs 21:25 “The lazy man’s craving will be the death of him because his hands refuse to work.”
2 Thessalonians 3:10 “For even when we were with you, this we commanded you, that if any would not work, neither should he eat.”


Jesus set the example for His followers. He was active and involved in all that was around Him, right up to the time of His death. That was even though His disciples fell asleep because they could not keep up with Him. In the parable of the talents, the man who buried his talent instead of investing it was condemned (Matthew 25:14 – 30).

In that same chapter, Jesus talks about rewards and condemnations for how people use their time and their talents (verses 31-40). Feeding the hungry, giving water to the thirsty, visiting prisoners, taking in the homeless, and ministering to the sick are all activities that involve work.

The pandemic has shown what happens when humans don’t do what God has called them to do. Labor Day in the United States reminds us of the relationship between humans and labor. For Christians, it’s a reminder of what we must do with our time and talent.

The Christian Concept of God

The Christian Concept of God from the Bible

We have been examining the Christian concept of God for the past several days. The Bible tells us that God is beyond time, space, and matter/energy because He created them. As science goes deeper into understanding the structure of matter/energy, it becomes increasingly evident that there are forces beyond our familiar physical laws. Quantum mechanics and studies of the nature of matter show that creation has not been merely a physical process.

Heaven and hell are not physical places with physical rewards or punishment. When we die, our soul, that part of us created in God’s image, will no longer be limited by time. All the bad things that time brings will be gone, “…there will be no more death, neither sorrow nor crying. Neither shall there be any more pain, for the former things have passed away” (Revelation 21:4).

We struggle to understand metaphors in the Bible that use physical pictures of things that are not physical. The result is that when we approach them with a physical understanding alone, we become confused. If we understand the biblical Christian concept of God, these metaphors become much clearer, and our freedom as Christians is greatly enhanced. Christ’s promise of life after our physical life is over gives us joy and comfort beyond physical understanding. We can rejoice in knowing that the things that afflict us in this life will be gone, and our future will be secure and filled with joy in spiritual union with our Creator.

An Earthly Kingdom

An Earthly Kingdom in Jerusalem?
Jerusalem from the Mount of Olives

For the past few days, we have been looking for the biblical Christan concept of God. We have observed that atheists, and even people who call themselves Christians, fail to understand what God is. We are familiar with the physical world, so we look for God to bring a physical earthly kingdom.

The New Testament calls for us to understand that Christians serve a God who is not a man—or woman. Galatians 3:28 tells us that “there is neither male nor female” in Christ’s kingdom, the Church. This same message appears in Romans 10:11-13 and Colossians 3:11. In John 18:36-39, Jesus told Pilate, “My kingdom is not of this world,” making it clear that He was not bringing in a physical earthly kingdom. Yet, even today, some Christian groups interpret Christ as a military leader who will defeat all other belief systems and establish a physical kingdom in Jerusalem.

This struggle to understand God goes back to Genesis 1:1, describing the creation of time, space, and matter/energy. When Peter describes the end of the world in 2 Peter 3:3:10-12, he says that time will end and the physical cosmos will “dissolve in fervent heat” (verse 12). God is in a higher dimension than time or the material cosmos. He created the human soul in His image–not our physical bodies.

In 1 Corinthians 15:35-55, Paul conveys the concept of a kingdom not of this world. People in that day didn’t understand it, and still today, many Christians don’t understand it. The fact that Christ’s kingdom is not an earthly kingdom makes it, unlike any human system. That brings us back to the biblical Christian concept of God, and that is where we will conclude tomorrow.

The Things We Pray For

The Things We Pray For

Yesterday, we said that understanding what God is and what He desires for us can help us understand the meaning and importance of prayer. There is nothing wrong with praying to God for our physical needs. You can see that in the model prayer, “Give us this day our daily bread” (Matthew 6:11). However, it is illogical and unbiblical to get upset when God doesn’t answer our physical requests in the way we desire. Failure to receive the things we pray for is rooted in a failure to understand what God is and what He desires for us.

When I was an atheist playing football in high school, one of my teammates asked God for victory in every game. We played a team from a Christian high school late in the season. One of their team members told me that he knew they would beat us because they had prayed to God for victory. Unfortunately, we lost that game, and my teammate, who had been praying for us to win, decided he needed to be an atheist like me because, clearly, God didn’t answer prayer.

There have been wars between cultures that worshipped the God of the Bible. Examples are the American Civil War and the Irish wars between Catholics and Protestants. Both sides prayed to the same God for victory. However, winning a victory would mean killing people who were Christians on the other side of the conflict.

When I gave my lectures in Ireland, people expressed great interest in my message that science supports belief in God. However, many people wanted nothing to do with the Church because of the history of religious warfare. A Catholic priest in full clerical garb attended one of my lectures and informed me that he was an atheist. He was still conducting mass because that was the source of his income, but he didn’t believe in God. The things we pray for reflect our concept of God.

It becomes clear that even “religious” people often do not understand the Christian biblical concept of God. We will continue with that thought tomorrow.
