T Cells and Antibodies Fight Pathogens

T Cells and Antibodies Fight Pathogens

T lymphocytes or T cells are one of the most amazing devices designed into your body. T cells are critical to defending your body against viral invaders (pathogens). T cells are white blood cells that work with proteins called antibodies to recognize and fight pathogens. When your immune system detects a pathogen, your body starts producing T cells and antibodies to fight it.

T cells are created in the bone marrow and then travel to the thymus gland right in front of the heart, where they mature. The T cells then circulate in the blood and lymphatic system, searching for pathogens by detecting the antigens on their surfaces. When they find pathogens, T cells and antibodies work to neutralize them, protecting your cells.

If a virus is new, it may take time for your body to generate the necessary T cells and antibodies to fight it. That’s where vaccines step in to give your body a head start so that if you get infected by a new pathogen, your body is prepared and ready to fight it. After clearing the infection, some of the T cells remain in case it returns.

The amazing immune system is the product of careful design and not some kind of accident. The more complexity we see in a system, the less likely it is a product of blind chance. The statement in Psalms 139:14 describes the wonder of T cells and antibodies: “I will praise you, Lord, for I am fearfully and wonderfully made: marvelous are your works and that my soul knows full well.”

Frozen Frogs that Thaw Out and Live

Frozen Frogs that Thaw Out and Live

Among the most incredible designs in the natural world is how God equipped various animals to survive winter. Some of the methods are relatively obvious. Burrowing deep under the frost line is one method. We have noted in the past the complex way bears give birth to young and retain urine while hibernating. Wood frogs are unique because they don’t burrow underground for protection from the cold. Instead, they become frozen frogs during the cold months.

Wood frogs are amphibians, meaning they are cold-blooded because they can’t generate any body heat. In winter, the water freezes in the frog’s cells but doesn’t expand and rupture them. They have a natural antifreeze preventing the cells from bursting when they freeze.

When spring arrives, the water inside the frog melts, and the frog awakens. Males immediately begin making a sound like a quacking duck, attracting females. Next, the male will grasp the female with his forelimbs wrapping around her torso. He squeezes until she releases her eggs into the water, where he fertilizes them. The males have a thumb that swells during the breeding season, enabling them to grasp the females.

Scientists are trying to understand how the wood frog’s cells can freeze without rupturing, causing death. Medical science wants to know how to freeze living tissue without damaging it for organ transplants. Many questions are still unanswered in the freezing and recovery of the wood frog. Why don’t all amphibians have this capability, and why is it limited to these creatures?

God has designed special equipment and chemicals to sustain life in all kinds of environments. So when we look at incredible designs, such as frozen frogs, we can know there is a God who created these unusual life forms. (Romans 1:20).

The Bible is Easy to Understand

The Bible is Easy to Understand

One of the common challenges to Christianity is that the Bible is hard to understand. Coupled with that are claims that the Bible is full of mistakes and contradictions. However, the fact is that the Bible is easy to understand if we apply a few common sense practices.

Skeptics “cherry-pick” the Bible to try to make it look confusing. They take a small section of the Bible and lift it out of context, ignoring its purpose, writing style, or the original language’s meaning. For example, they quote Luke 14:26 as saying that the followers of Christ must hate their whole family. The passage is talking about priorities and simply saying your faith has to come first in your life for it to have meaning. We see in 1 Timothy 5:8 that if Christians don’t care for their families, they are worse than an infidel. 

There are a few simple rules that will help an honest reader know that the Bible is easy to understand:

Divide the Old Testament from the New Testament (2 Timothy 2:15). Galatians 3:24-25 tells us the purpose of the Old Testament and that we are no longer under the Old Law. (Read Colossians 2:8-17.)

Understand the purpose of each book. The gospels tell the story of the life of Christ. The letters address Church matters after Jesus ascended to heaven. Revelation addresses the struggles of the early Church, not the politics of modern times.

Avoid what Peter calls “cunningly devised fables” (2 Peter 1:16, 20). Much of what you hear about the book of Revelation is the embellishment of a book written to those who were oppressed and needed to know the good news about “things that must shortly come to pass” (Revelation 1:1).

Understand that humans broke their relationship with God, and the Bible is God telling us how to restore it. Peter’s sermon in Acts 2 does that, and the people who heard that message responded with, “Men and brethren, what shall we do?” (Acts 2:37). Verse 38 tells us what to do, assuring us that restoration is available from God.

All alternatives to the biblical message about how to live your life are destined to fail. Read the biblical message and act upon it. Read 2 Peter 1:4-8, Galatians 5:19-23, Matthew 5:21-48, and 2 Timothy 3:16-17. Then do what those verses say.

If you are interested in the history of the human relationship with God, read the Old Testament. If you want to know how to restore your relationship with God, read the book of Acts. If you want to know how to live the Christian life in a secular world, read the letters of Paul. The Bible is easy to understand, and you don’t need a theology degree. Don’t let anyone tell you what the Bible says. Please read it for yourself and act upon what it says. It is the Word of God.

Rapidly Increasing Drug Use Data from NIH

Rapidly Increasing Drug Use Data from NIH

One of the consequences of our culture’s rejection of God and Christian teachings is that people are looking for other ways to deal with life’s stresses. The National Institutes of Health’s annual survey shows rapidly increasing drug use in the United States.

In 2011, 29% of those ages 19 to 30 used marijuana 20 or more times in the preceding year, and 6% said they were daily users. In 2021, 43% had used marijuana 20 or more times in the past year, and 11% indicated they were daily users. In 2011, 3% said they used psychedelics such as magic mushrooms or LSD, and that number is now 8%. Data also shows a significant increase in vaping and alcoholic drinks mixed with THC.

The increasing legalization of marijuana is part of the cause for rapidly increasing drug use. In that case, these numbers should quickly grow in the next year as marijuana legalization continues to expand. This is a complex issue because we don’t know the long-term consequences of using marijuana and the chemicals derived from it.

The Christian concept of the body as the dwelling place of the Spirit of God means that Christians should take care of the body. Recreational drugs have no value for the well-being of the physical body but can have value in particular situations. Proverbs 31 states the wisdom of leaders not drinking but suggests using strong drink to help at the time of death. “Give strong drink to him who is ready to perish and wine to those that be of heavy hearts. Let them drink and forget their poverty and misery” (Proverbs 31:4-7). In 1 Timothy 5:23, Paul tells Timothy not to drink the contaminated water prevalent in that day but use a little wine to avoid illnesses from the water.

James 5 encourages Christians to rely on each other and on God to handle life’s challenges. Using drugs as a social lubricant or an antidepressant will have long-term negative consequences. We are only beginning to see the collateral damage of rapidly increasing drug use in the world around us.

God Created Two Books

God Created Two Books

How have you arrived at the belief system that governs your life? God created two books we are called to use as the basis for our lives, morals, and religious practice. Since these two books have one author, they must be complimentary and cannot conflict. It is strange that many people read one book and refuse to look at the other. That is true of both atheists and religionists.

One of the books is the Bible, and it calls us to use it as a guide for life. Second Timothy 3:16-17 states it very clearly: “All scripture is given by inspiration of God, and is profitable for teaching, for training, for guiding and for moral discipline so that the man of God may be complete and adequately equipped for all good work.” Atheists reject this book because it involves denying one of a few physical pleasures and gives a purpose in living other than survival. Living selfishly has its rewards, and that is attractive.

God created two books, and the second book is the creation itself. The Bible is full of admonitions to use the things God has created as a means of knowing truth and learning how to live a productive and rewarding life. The Old Testament calls us to use what we see in the world around us as a guide to life. The entire book of Job carries that message. Numerous Psalms call us to see God’s wisdom and design and shape our beliefs in them. (See Psalms 8:3-9; 19:1; 53:1-4; 139:14-16.) Proverbs is full of admonitions to learn from the creation. (See Proverbs 6:6; 8:1-7 and 22-36.)

In the Sermon on the Mount, Jesus used the created world as the basis of much of His teaching. (See Matthew 6:26-30; 7:16-20.) Romans 1:18 – 23 says of humans, “That which can be known of God lies plain before their eyes for God himself has made it clear to them. For those things of God which the eye can not see, ever since the creation of the world, are clearly perceived through the things that are made, and are clear to the eye of reason, even his eternal power and divine character so that men have no excuse.”

So God created two books, and it is clear why atheists do not wish to read and apply the Bible to guide their moral and spiritual lives. It is hard to understand why people who claim to believe in God refuse to look at the creation as a source of instruction and guidance. Some are too lazy to read the Bible and study its message, and others are too lazy to read the creation and learn its message. We need to read and study both books so that we can do what 1 Peter 3:15 tells us: “Revere Christ as Lord in your hearts and always be ready with your defense whenever you are called to account for the hope that is in you, yet argue gently and cautiously with meekness and respect.”

The Hippocratic Oath No Longer Used

The Hippocratic Oath No Longer Used
Bust of Hippocrates

In the past, the Hippocratic Oath was a sworn agreement made by medical students when they became doctors. It includes a promise “to share knowledge, to help the ill and not cause harm, and to never give a deadly drug or help another to use one.” Hippocrates (460 to 370 B.C.), a Greek physician known as the “father of medicine,” was concerned with the methods and ethics of medical treatment.

Hippocrates lived at the same time as Socrates, who extolled the doctor. He was in a clan known as the Asklepiads, devotees of Asklepios, a Greek god of health. They swore to the gods to keep themselves “pure and holy,” help the sick, and avoid “wrongdoing and harm to patients.” They vowed not to breach patient confidentiality, perform surgery for which they had not been trained, cause an abortion, poison, euthanize, or sexually abuse a patient.”

The Hippocratic Oath appeared in a collection of some 70 texts called the Hippocratic Corpus. By the 10th century, Christians had replaced Greek divinities in the Hippocratic Oath with the God of the Bible, and medical schools used that version until modern times. By the early 20th century, that began to change. In 1928 only 14 of 79 medical schools required their students to swear the Hippocratic Oath. No medical school in America requires it today.

In recent years, the ethics of medicine has become a major issue. Special interest groups like “Compassion and Choices” advocate for physician-assisted suicide. Laws in several states now allow doctors to prescribe lethal amounts of drugs for use in suicide.

Is the morality of a doctor important when you or a loved one are in declining health? What is the difference between a doctor who believes the body is the “temple of the Holy Spirit” (1 Corinthians 3:16) and one who believes in survival of the fittest? This is a significant issue for all of us dealing with end-of-life issues, as all eventually will.

Wormholes, Black Holes, and the Beginning

Wormholes, Black Holes, and the Beginning
Wormhole Illustration

One of the strongest arguments for God’s existence is the fact that all evidence indicates that there was a beginning to the creation. Space and time are not eternal. If the creation began, there had to be a cause for space/time. The only way to avoid that is to show that space/time is eternal. The classic atheist argument is that if God has always existed, it is just as valid to claim that space/time has always existed. One way to support the view that space/time is eternal is to suggest that tunnels called wormholes exist between black holes in the cosmos.

The idea is that wormholes would allow matter/energy to fall into a black hole in one area of space and re-emerge in another part of space. By falling into a black hole, the conservation laws of science and the laws of thermodynamics would be invalidated. Physical laws, entropy, and all other boundaries would start over when the matter/energy emerged at the wormhole’s other end. All matter/energy in the cosmos would experience these changes through an infinite number of wormholes, and since the laws of science would be re-established, this could go on forever. In essence, this is a new version of last century’s oscillating universe theory.

Science fiction writers have used this idea as a way for aliens to quickly travel anywhere in the cosmos. The distances between galaxies are in the millions of light years, so traveling even at the speed of light would take millions of years. If wormholes connected the galaxies, you could take a shortcut traveling instantly from one galaxy to another. This is an imaginative proposal, but the evidence doesn’t support it.

If every galaxy is connected to other galaxies by wormholes, we should be able to see matter/energy emerging from every galaxy we observe. If the wormhole were in empty space, you would see white holes where this would be happening. We don’t see any such objects anywhere. Instead, we see black holes and even have photographic evidence of their existence. However, the nature of a black hole is that matter/energy falls into it and is compressed smaller and smaller to an infinitely small point. Nothing comes out of a black hole by any process.

Scientists speculate that ultimately, all the matter/energy in the cosmos will fall into one supermassive black hole and be destroyed. That reminds us of the words of Peter in 2 Peter 3:10-12, “The elements will be dissolved.” There was a beginning, and it was caused by God, an entity outside of space/time, and there will be an end.

Endothermic or Ectothermic – What’s the Difference?

Endothermic or Ectothermic – What’s the Difference?

You are an endothermic mammal. That means your body’s metabolic rate controls your internal body temperature. We describe that condition by saying you are “warm-blooded.” Many life forms on our planet are “cold-blooded” (ectothermic) because the environment controls their internal body temperature. The limitation of being cold-blooded is that it requires warm environmental temperatures. Ectothermic life forms can’t survive in polar areas. Endothermic life can survive almost anywhere.

During the time of the dinosaurs, the planet was very hot. That means biological systems, including plants, grew quickly. Those conditions were part of God’s preparation of resources that humans would need, including oil, coal, topsoil, and oxygen. However, the geologic record shows a point in Earth’s history when the climate radically changed. 

As the entire planet cooled, areas at or near the poles became too cold for cold-blooded life to exist. Studies of bone growth rates and oxygen isotopes in ancient bones indicate a rapid change. This change would not be a problem for warm-blooded animals but would reduce the number, size, and activity of cold-blooded life forms.

The challenge would be to design living creatures that can translate food into enough internal heat to survive in a cold environment. Science News reported on studies of the inner ears of reptiles and mammals. In warm-blooded animals, the inner ear fluid is less viscous, requiring that the ear canals become smaller. As a result, fossils show a sharp change in inner ear morphology at the time when Earth’s climate became colder. 

Many other changes were required for life to go from ectothermic to endothermic. However, the inner ear structure is preserved in the fossils, making it useful for scientists to study the history of life on Earth. The complexity of endothermy reminds us again of the words of Psalms 139:14, “I will praise you, for I am fearfully and wonderfully made: marvelous are your works.” In our time of changing climate, the design of life continues to show the wisdom involved in life’s creation.

Our Planet is Unique and Bizarre

Our Planet is Unique and Bizarre

Human technology has allowed more observations of our planet than most of us realize. NASA currently operates around 30 Earth-observing missions accumulating massive amounts of data. We know about changes in sea level for the Earth’s oceans within a fraction of an inch. Hourly, we can know the areas of our planet covered with snow. We measure the amount of tree cover on Earth and minute-by-minute changes in the planet’s atmosphere. The result of all this detecting and measuring is that we know that our planet is unique and bizarre.

Earth is the only planet we have seen with an active water cycle that causes weather and allows the recycling of water resources. It is also the only known planet with active plate tectonics, recycling minerals within Earth’s crust using earthquakes and volcanoes while releasing volatiles that create and maintain our atmosphere.

We have only recently understood the Moon’s role and how important it is for life to exist on Earth. We know that it was formed in a catastrophic impact that determined its location and size. The size and distance from Earth are precisely right to cause the strength of our tides and give our planet a stable 23.4-degree tilt. Without the Moon, our Sun would cause very weak tides causing our coastlines to be much different, while the planet’s axis of rotation would wobble, destabilizing the climate.

Our planet is unique and bizarre because it has been shaped by vegetation, responsible for the atmosphere’s oxygen content of 21%. The typical astronomical atmosphere of planets is dominated by methane and carbon dioxide. Photosynthesis uses sunlight and carbon dioxide to produce the oxygen we breathe. Science is still struggling to understand the source of the massive amount of minerals we have on Earth. Meteorites have a small number of minerals, and while the Moon has a larger number, Earth’s variety of minerals is astounding.

Discover magazine featured an article discussing NASA’s studies of planet Earth. It stated that Earth observations have taught scientists one sure thing: “Our planet is unique and bizarre, with unusual properties that don’t match those of any other world we’ve seen, either in our own solar system or beyond it.”

For those of us who understand the science involved and believe in God as the creator, this is no surprise. Proverbs 8 finds “Wisdom” saying, “The Lord possessed me in the beginning of His way …” We see that beautifully demonstrated as we look at our planet and marvel at the intelligence of the Designer who produced it.

Dead Sea Scroll Fragments Missing

Dead Sea Scroll Fragments
Dead Sea Scroll Fragments on Display

The first Dead Sea Scrolls were accidentally discovered seventy-five years ago. Ever since that time, archeologists, biblical scholars, and politicians have struggled for control of the scrolls. The Dead Sea Scrolls disprove claims made by many atheists and skeptics who deny the accuracy and authenticity of the Bible. Unfortunately, however, there are a substantial number of missing Dead Sea Scroll fragments.

The fall 2022 issue of Biblical Archaeology Review reported that missing Dead Sea Scroll fragments include a large fragment from a Samuel scroll and three fragments from a Daniel scroll. There are more than 1,000 others. They have either been stolen, destroyed, misplaced, or possessed by someone who does not want them to be available to scholars and the public. Fortunately, scholars photographed some of the missing fragments before they disappeared.

Thirty years ago, Hershel Shanks, a well-known author and publisher, campaigned to get the people controlling the scrolls to make them available to scholars and the public. Tens of thousands of scroll fragments have been discovered, and most scholars have still not gained access to the ones known to be in repositories, not to mention the missing Dead Sea Scroll fragments.

This situation reflects negatively on the state of archaeology in the world today. Competition among archaeologists and biblical scholars has morphed into an attempt to control who has access to these artifacts. This conflict involves national interests, professional reputations, and grants. The religious beliefs of some archaeologists are also a factor.

Hopefully, the missing fragments will eventually be found, and all of them will be made available to everyone who should have access to them. These scrolls verify much of the biblical record and answer many of the challenges of those who oppose Christianity.
