There was an excellent podcast, by Dr. Robert Godfrey, titled Two American Revolutions.
The second ‘revolution’ corresponds to (if I’m remembering correctly) the second great awakening.
The podcast is part of Godfrey’s series A Survey of Church History.
from Renewing Your Mind podcast (normally by RC Sproul)
