I have heard from my teachers that when something major happens in the world, this is a message from Hashem. But it is a message for Israel and actually for the religious people in our nation- because (Seforno on tzoraas) they are the ones who are listening.
So with the COVID epidemic, or with the present situation with Hamas which is even so much more directed to our people specifically, we are receiving a very strong message from Hashem, with his midah of judgment.
How are we supposed to listen to such messages? I hear frequently that each individual should assess themselves and try to find things that they need to improve and ways to do it. That is surely a wonderful thing to do.
But I am wondering, isn't it more likely that the message being sent is also for the nation as a whole? It seems to be a single message, not a lot of little messages to individuals, though of course details vary from person to person.
If that is so, then our leaders would have to direct our entire nation on a major push to improve a major problem. Is that something that they are doing now?
As a middle ground, could a response depend on whole communities?
According to that Seforno I mentioned: What good is a very loud message from Hashem, even if we are listening, if none of us can understand it?
What sources discuss this? Have people heard from our gedolim about such issues?
