I have heard some of our believers, young in the faith, question if God is to blame, due to these recent events. I am sure most, if not all, of us here do not believe God is to blame, but for those who might I find this comforting.
"As therefore the physician is a benefactor even if he produces distress or pain in the body, for he fights the illness and not the sick person, so also God is good, who provides salvation to all, through particular punishments. And you do not accuse the physician of any wrong in his cutting and burning and complete mutilations of the body; but rather you probably pay him money and you call him a savior, since he has produced illness in a small part of the body to prevent the suffering from spreading throughout the whole of it. But whenever you see a city fall down on it's inhabitants in an earthquake, or a ship and it's whole crew lost at sea, you do not hesitate to wag your tongue in blasphemy against the true Physician and Savior. And further, one must understand that there are moderate and curable illnesses of human beings, which are helped by care, but whenever the disease is shown to be too severe for treatment, it becomes necessary to cut off the part that has become useless, so that the illness does not continue and proceed to spread into the vital organs. Therefore, as the physician is not the cause of the surgery or the cautery, but the illness is, so also, as the obliteration of cities has its source in the excess of those who have sinned, God is acquitted of all blame."
St. Basil the Great, On the Human Condition, p.68
