I think we need to remember that God doesn’t care too much about kings and Nations and groups of people, with the exception of Jews. But he IS concerned about the salvation of each individual. And He does work for good for all that believe in Him. Of course, the end of America and us scrounging around in the wastelands may be what it takes to make our faith in Him stronger.
I met a Chinese missionary that said the Christians in China were praying that Christians in America would be persecuted (like they were) so that our faith would grow. I told him “Tell them thanks. And tell then to knock it off!”
Did not the tribulation make Job stronger??
