Some Viruses Are Beneficial

Why is a new coronavirus (SARS-CoV-2) causing lots of disease (COVID-19 or C19) and death around the world? The answer: God created all things “very good” (Genesis:1:31And God saw every thing that he had made, and, behold, it was very good. And the evening and the morning were the sixth day.
See All...). Death and disease entered the world only after the Fall, when our ancestor Adam sinned (Genesis:3:17And unto Adam he said, Because thou hast hearkened unto the voice of thy wife, and hast eaten of the tree, of which I commanded thee, saying, Thou shalt not eat of it: cursed is the ground for thy sake; in sorrow shalt thou eat of it all the days of thy life;
See All...–19, Romans:8:20For the creature was made subject to vanity, not willingly, but by reason of him who hath subjected the same in hope,
See All...–22). Therefore, God must have created viruses very good too!

Even today, most viruses are beneficial (see creation.com/wuhan-coronavirus). A healthy human body probably has about 10 times more viral cells than human cells! One epidemiologist said that if all viruses in the world disappeared, it would be nice for about 36 hours, then we would all die! But after the Fall, some viruses became harmful and even deadly—usually after escaping from the creature it was designed for. E.g. both the C19 and Ebola viruses had a useful role in bats.
