Except when they aren’t peaceful... hello civil war? hello BLM?
We shouldn’t white wash this. Man is fallen and doesn’t suddenly proceed to be unfallen even when having entered the land which has had the largest sincere (unforced, no state church, no official religion) gospel presence in the entire world.
However. America’s model has a way of rewarding returns to God that other countries’ model doesn’t. Rebellions against God see a more spectacular disaster in this atmosphere of aspiration to freedom, but the returns see a more spectacular healing too. I think we are about to see the latter happening before very long.
You actually prove my point. The fractures of slavery and states rights were suppressed by compromise as much as possible for 70 years (or longer depending how you calculate). The issue eventually had to explode in great bloodshed.
