“Why would God continue to bless the USA, given the changes to our society in the past couple of generations?”
Because thousands of faithful hit their collective knees every day and pray for our Nation. We need never to forget the power of prayer and the mercy of our Heavenly Father.
I pray you are correct, and it gives me hope that there is precedent: Genesis 18:32
Nevertheless, withholding wrath is not the same as continuing to bless. We may very well survive, but with a very different kind of life to which we’ve become accustomed.
