Well, I think its true that the revolutionary concept that all man are equal and defined by their moral behavior, not their class, was fruit from the 1st great awakening. There's a few books out there that support that, and the influence of the 2nd great awakening on slavery, and the 3rd great awakening on the depression. I think you can see that pretty clearly in history.
And if you map the differences between the 3 awakenings I think you can see a steady drift from an emphasis of true spiritual awakening towards mere social action. If we are in a 4th awakening, it is less about faith and more about conservative moral outrage ... or liberal social conciousness. In other words, it originates less with God and His Word, and more from ourselves and what we think about God and His Word.
But that's the same cycle of development you can watch in the life of an individual. At the moment of regeneration, they are afire with the reality of a restored relationship (1st GA), but the feeling fades a little and they miss the feeling. So then they have a passion for personal holiness in themselves and others (2nd GA) perhaps to rekindle the feeling, and that's frustrating and unattainable, so then they move into social concern (3rd GA) which gives one the direct satisfaction from participation in what is "good." But that's tiring and you can get abused so the next phase is less hands on, but perhaps more vocal in the public forum over moral outrage ... and that's where we are now. After that I think we just mutter under our breath nostalgic epithets, and fade into irrelevance.
But God calls us to remember our first love ... I think we the people of these United States are gonna suffer a lot more than we do now before we see another time like the 1st great awakening. I don't think you can bring back the constitutional commitment of the founders without first having another great awakening.
TM7, I concur that the articles of confederation were stronger by far, and I would argue more firmly rooted in the ecumenical morality springing from the 1st awakening. But I think the constitution was a wise compromise that acknowledged we would lose our zeal over time and need a more sizeable set of stone tablets to lean on.
