I just finished reading the Light and the Glory series. The whole series is the about the birth of America, and the trials that it has gone through. As I posted before, throughout history, America has seen huge revivals. And usually before those revivals America is going through some tough times. The authors' note in the series sums up everything. I quote:
 
  "At the close of Uncle Tom's Cabin Harriet Beecher Stowe made an impassioned appeal: If the reader was moved by what he or she had read and wanted to help eradicate the stain of slavery, they should do so by all means available to them, starting with prayer. As we have seen millions have responded to her call. 
  The Great Prayer Revival of 1857-58 was a partial answer to those prayers, as a merciful God extended to the nation one last opportunity to hear His voice and turn and seek His face. Many did. But not enough. And so, what might have been a solution became instead a preparation.
  As 1860 drew to a close, men and women of spiritual vision could see armies of angels and archangels gathering for the coming struggle for the soul of America. They could hear the sound of distant trumpets that would never call retreat. 
  Now, as this century draws to a close, men and women of spiritual vision are again seeing signs and wonders, indicating that God's judgment, so long deferred, is close at hand. In the twelve years since we penned From Sea to Shining Sea, the moral standards of our society have deteriorated precipitously. The litany is all too familiar--soaring illegitimacy, divorce, and drug abuse. A blight of pornography has seeped into every corner of society. And the monstrous slaughter of the innocent unborn continues unabated.
  But perhaps the most fearsome aspect of what is becoming of us, is that we are growing inured to the decay. Scandal and corruption in public (let alone private) life now occur so frequently that our response is often to shrug and ask: Is there really anything that can be done?
  It is too late now for a human solution. But with God, nothing is impossible. We believe that the only hope for America is a full-scale, national revival. There are, even now, indications such a revival may be in the offing--pockets of genuine, sustained spiritual awakening in various cities. But as best we have a case of 'revival measles.'
  In order for revival to spread from coast to coast and border to border, more than a remnant of us will have to take God's promise in 2 Chronicles 7:14 to heart--to repent, seek His face, and turn from our wicked ways.
  We must do so at once. As Mrs. Stowe concluded, 'O Church of Christ [and we would include anyone who believes in the existence of God], read the sign of the times! A day of grace is yet held out to us...for not surer is the eternal law by which the millstone sinks in the ocean than the stronger law by which injustice and cruelty shall bring on nations the wrath of Almighty God.'
 The wrath she foresaw was the terrible, tragic ordeal of the Civil War. Heaven only knows what cataclysmic disaster awaits us if we do not, as a nation, turn back to Him. One thing is certain: We can hear the sound of distant trumpets."

 
 I would say with Harriet Beecher Stowe, if you have been moved by what you have read, and want to see a revival, you should do so by all means avalible to you, starting with prayer.
