Question

In another question you raised, you wrote that it is reasonable to think there would indeed be providence over “decent groups.”
You wrote: “What about the decent groups?”
But as far as I remember, you also hold, like I do, that it is almost never possible to know who is righteous (and all the accusations that come up nowadays against all kinds of supposedly righteous religious figures prove that).
 
It seems from your words that there are groups you do define as decent groups, and that it would be reasonable for individual providence to apply to them (even though we do not see it).
How do these things fit together—can one know which groups or people are righteous, or is it impossible to measure?
