The limitations of science

I am a fan of science. I was a boy at the time of the Apollo missions to the moon, and I watched full coverage of them on television. Over the years, my parents bought me a telescope, a microscope, a chemistry set, and a 100-project electrical kit. I got As in science all through school. I still keep up with the latest discoveries, from the exploration of Mars to the particles detected from split atoms.

Science provides many benefits. Science gives us longer and more productive lives, thanks to expanding knowledge about nutrition, sleep, exercise, medicine, therapy, and the battle against pests, from viruses and harmful bacteria to fleas, ticks, and tapeworms. But science cannot help us beyond death. Science cannot tell us whether any part of our being survives death. Nor can science reveal the destiny of that surviving entity, whether it will go to heaven or to hell.

Science is limited to studying the physical world. It can measure and describe matter and energy, but science cannot observe anything that does not consist of matter or energy. Science cannot prove or disprove the existence of God, angels, demons, or the human soul. It is not scientific to say that science disproves those entities, because the rules of science do not permit science to determine anything about the nonmaterial world.

Therefore, anyone who puts his or her faith in science is as mistaken as someone who puts his or her faith in money, or in political power, or in one’s own good deeds, or in Baal or Zeus or Thor. Money and politics and good deeds all have value; they each have a place in our lives. But none of them can take the place of God. None of them can do what God does for his people.

One of the benefits of science is that it changes. New discoveries invalidate prevailing theories and force the creation and testing of new theories about the material world. Isaac Newton applied mathematics to science. He found the equation that describes how gravity works. After Newton, science grew more and more mechanical, with the hope that one day science could explain everything in the universe. But Albert Einstein and other twentieth-century scientists showed that Newton’s mathematical and mechanical universe only describes matter and energy of moderate size. The rules change with the very big, the very small, and the very powerful.

Because science changes, it is unreliable. One researcher says coffee is good for people; the next researcher says coffee is bad for people. Efforts to eradicate the spread of disease and improve the cultivation of crops have damaged the environment by killing off insects and poisoning the creatures that eat insects. Food additives, pesticides, industrial chemicals, and perhaps even life-saving vaccinations can have damaging side effects, which may explain the increase in recent times of autism, anxiety, depression, eating disorders, substance abuse, and intolerance of one another. The poisonous social atmosphere in which we live may literally be poisoned by the same scientific advancements that were intended to improve our lives.

The person who relies on science and scientists to provide all Truth is missing a great deal. The knowledge that our souls will spend time elsewhere when we die—a better place or a worse place, depending upon who we know and trust—and that our bodies will be raised to eternal life at the dawn of the new creation—this knowledge shapes much of what we choose to do today. Knowing the Creator of the universe is far more important than knowing when and how the dinosaurs lived. Knowing that the life and death and resurrection of Jesus provides forgiveness of sins, fellowship with God, and victory over all enemies is far more important than encyclopedic knowledge of all the chemicals or all the planets and planetoids or all the subatomic particles.

One reason science seems to be more valuable than religion is that science has, over the years, provided material explanations for phenomena (such as thunderstorms and epileptic seizures) that were formerly attributed to spiritual causes. One might chart the number of phenomena that are explained by science and no longer attributed to spirits and assume that the need for religion will disappear. But even though science can improve our lives in this world, it gives us no reason to go on living. Nor can science guarantee eternal life in a better world after death in this world. Science cannot lift the guilt of a person who knows that he or she has done wrong. Science cannot teach people how to forgive one another and live in harmony. Science is beneficial, but it cannot replace religion. A life based on science is as empty as a life based on money or politics or entertainment.

I remain a fan of science. But my faith is in God. Science studies the things God made. Theology studies God. God is not too small for science; he is too big for science to grasp, too powerful for science to measure, too grand for science to explain. I thank God for all the things science has discovered about his creation. I praise God for who he is, information which science cannot supply. J.
