Among the many questions I have received on my social media pages is this one: Why would an all-powerful and all-loving God create a world in which viruses exist?

As I explain at length in my book Why the Universe Is the Way It Is, it can be argued that God had multiple reasons for the laws of physics that he chose to govern the universe and Earth.1 I believe one of the more significant reasons is using these laws as tools in his hands for the rapid and efficient eradication of evil and suffering while he simultaneously enhances the free wills of billions of humans who choose his redemption.

The multiple purposes God has for the laws of physics necessitate that there will be design tradeoffs. However, it appears that God has optimized these tradeoffs so that all his purposes for creating the universe and human beings will be fulfilled in as beneficial a manner as possible.

I address many of these tradeoffs in my book More Than a Theory.2 There I point out that we live on a planet with tornadoes, hurricanes, earthquakes, wildfires, and tsunamis, but each of these so-called natural disasters is essential for our existence. They are optimized to bring the greatest possible benefit to humans and the rest of Earth’s life. Viruses are in the same category.

Benefits of Viruses
Life-forms on Earth larger and more complex than microbes would be impossible without an abundance of viruses. Without viruses, bacteria would multiply and, within a relatively short time period, occupy every niche and cranny on Earth’s surface. The planet would become a giant bacterial slime ball. Those sextillions of bacteria would consume all the resources essential for life and die.

Viruses keep Earth’s bacterial population in check. They break up and kill bacteria at the just-right rates and in the just-right locations so as to maintain a population and diversity of bacteria that is optimal for both the bacteria and for all the other life-forms. It is important to note that all multicellular life depends on bacteria being present at the optimal population level and optimal diversity. We wouldn’t be here without viruses!

A high human population and advanced global civilization would not be possible without Earth’s water cycle providing copious amounts of precipitation all over the continental landmasses. All the precipitation components (rain, mist, snow, hail, and sleet), however, require microscopic seeds (or nuclei) to form. In most environments, the most important seeds for precipitation are viruses and bacterial fragments resulting from viral attacks. Wind carries these “seeds” into the atmosphere where ice crystals form around them. Liquid water clumps onto the ice crystals, making them progressively larger. These augmented ice crystals turn into rain, snow, or other forms of precipitation and fall to the ground. While dust and particles of soot can also serve as seeds or nuclei for the formation of raindrops and snowflakes, viruses and bacterial fragments allow the initial ice crystals to form at warmer temperatures. We would not have nearly sufficient precipitation over a sufficiently broad area to sustain our agriculture and civilization if it were not for viruses.

Viruses also play a crucial role in Earth’s carbon cycle. They and the bacterial fragments they create are carbonaceous substances. Through their role in precipitation, they collect as vast carbonaceous sheets on the surfaces of the world’s oceans. These sheets or mats of viruses and bacterial fragments sink slowly and eventually land on the ocean floors. As they are sinking they provide important nutrients for deep-sea and benthic (bottom-dwelling) life. Plate tectonics drive much of the viral and bacterial fragments into Earth’s crust and mantle where some of that carbonaceous material is returned to the atmosphere through volcanic eruptions.

Thanks to Earth’s aggressive carbon cycle the global environment enjoys a great diversity of life that has continual access to the nutrients it needs. Earth’s carbon cycle also plays a critical role in regulating the amounts of carbon dioxide and methane in the atmosphere. Thanks to viruses we have the carbon cycle running at the rate we need and the amounts of atmospheric greenhouse gases that are optimal for our existence and our civilization.

Additionally, viruses already are playing significant roles in medical therapies and in advancing medical technology. In the near future, we can look forward to medical practitioners exploiting viruses to combat cancer and cure genetic diseases.

Making Viruses Worse

As with any good thing in nature, there are potential downsides, which can be made a lot worse by human neglect, abuse, and sin. Mosquitoes are a good example of how we humans made things a lot worse than God intended. Before humans messed things up, mosquitoes occupied only about 10 percent of Earth’s land area, cleaned up debris (like lemming poop), and provided food for many freshwater fish species. Now they occupy over 99 percent of Earth’s land area and are a nuisance and health hazard for much of the human population.

As with mosquitoes, humans have made viruses a lot worse than God intended. If only we had consistently practiced the health mandates written in the Old Testament, we very likely would not have had to deal with HIV, SARS-1, MERS, and SARS-2 (responsible for COVID-19). These are all viruses that were present in animals and jumped to human beings.

We make those jumps more likely where we have have dense populations of domesticated and/or wild animals in close contact with dense populations of humans. The larger, the denser, and the more stressed those animal and human populations are, the greater the opportunity for relatively benign viruses to mutate and become killer viruses.

My prayer is that we learn from our experience with COVID-19 how to better prevent such pandemics from occurring in the future. Changing the ways we manage and trade our domesticated animals to minimize their crowding, stress, and contact with dense crowds of humans would be a start. Minimizing stress and maximizing personal health, fitness, and hygiene in human populations, especially among the poor, is especially important. Let compassion, kindness, and wisdom reign for our benefit and the benefit of our animals!

About The Author

Dr. Hugh Ross

Reasons to Believe emerged from my passion to research, develop, and proclaim the most powerful new reasons to believe in Christ as Creator, Lord, and Savior and to use those new reasons to reach people for Christ. I also am eager to equip Christians to engage, rather than withdraw from or attack, educated non-Christians. One of the approaches I’ve developed, with the help of my RTB colleagues, is a biblical creation model that is testable, falsifiable, and predictive. I enjoy constructively integrating all 66 books of the Bible with all the science disciplines as a way to discover and apply deeper truths. 1 Peter 3:15–16 sets my ministry goal, "Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have. But do this with gentleness and respect, keeping a clear conscience." Hugh Ross launched his career at age seven when he went to the library to find out why stars are hot. Physics and astronomy captured his curiosity and never let go. At age seventeen he became the youngest person ever to serve as director of observations for Vancouver's Royal Astronomical Society. With the help of a provincial scholarship and a National Research Council (NRC) of Canada fellowship, he completed his undergraduate degree in physics (University of British Columbia) and graduate degrees in astronomy (University of Toronto). The NRC also sent him to the United States for postdoctoral studies. At Caltech he researched quasi-stellar objects, or "quasars," some of the most distant and ancient objects in the universe. Not all of Hugh's discoveries involved astrophysics. Prompted by curiosity, he studied the world’s religions and "holy books" and found only one book that proved scientifically and historically accurate: the Bible. Hugh started at religious "ground zero" and through scientific and historical reality-testing became convinced that the Bible is truly the Word of God! When he went on to describe for others his journey to faith in Jesus Christ, he was surprised to discover how many people believed or disbelieved without checking the evidence. Hugh's unshakable confidence that God's revelations in Scripture and nature do not, will not, and cannot contradict became his unique message. Wholeheartedly encouraged by family and friends, communicating that message as broadly and clearly as possible became his mission. Thus, in 1986, he founded science-faith think tank Reasons to Believe (RTB). He and his colleagues at RTB keep tabs on the frontiers of research to share with scientists and nonscientists alike the thrilling news of what's being discovered and how it connects with biblical theology. In this realm, he has written many books, including: The Fingerprint of God, The Creator and the Cosmos, Beyond the Cosmos, A Matter of Days, Creation as Science, Why the Universe Is the Way It Is, and More Than a Theory. Between writing books and articles, recording podcasts, and taking interviews, Hugh travels the world challenging students and faculty, churches and professional groups, to consider what they believe and why. He presents a persuasive case for Christianity without applying pressure. Because he treats people's questions and comments with respect, he is in great demand as a speaker and as a talk-radio and television guest. Having grown up amid the splendor of Canada's mountains, wildlife, and waterways, Hugh loves the outdoors. Hiking, trail running, and photography are among his favorite recreational pursuits - in addition to stargazing. Hugh lives in Southern California with his wife, Kathy, and two sons.
