Why did God allow the coronavirus pandemic?

As Jesus passed by he saw a man blind from birth. His disciples asked him, “Rabbi, who sinned, this man or his parents, that he was born blind?” Jesus answered. “Neither he nor his parents sinned; it is so that the works of God might be made visible through him. We have to do the works of the one who sent me while it is day. Night is coming when no one can work. While I am in the world, I am the light of the world.”

— The Gospel of Saint John, 9:1-5
