What happened to Israel even though it was under God's care?

Les explains that the nation of Israel started on that high plain with the knowledge of God. But even under the very auspices of the Creator God, they went down, down, down, down, until finally God had to say, 'There's no remedy.' There was no remedy because they had gone so far. He compares this pattern to Pharaoh, whose great and mighty Egypt became a shambles because of his own arrogance, and to other empires and nations that may begin with a high level of spirituality and knowledge of God but degenerate. After the Reformation, Europe was aflame with the Word of God, yet it went the same track, down, down, down, until prior to World War II it was as rotten and ready as today.
