When the Bible says "Blessed is the nation whose God is the Lord" (Psalm 33:12), it leaves no doubt about what brings stability and strength across the land.
On the other hand, if the nation, like the prodigal son (Luke 15), chooses the wrong road, it soon becomes a prodigal nation mired in a societal pigsty of mayhem and misery. It is, nonetheless, a course that can be reversed bringing full restoration.
