Theological Conflict at the Center of Revival?

In Jonathan Edward's sermons Sinners in the Hands of an Angry God and Divine and Supernatural Light and in his account of the revivals around Northampton in Faithful Narrative mention is made of the “Arminians” and others who preach a heterodox faith.  Though the conflict with those who do not adhere to Edward’s Reformed faith is not the central focus of his writings, it appears to me that theological conflict possibly played a greater role in the revivals of Edward’s day than I had originally thought.  Was it specifically the mixing of distinct theological traditions and the theological conflict inherent there that lead to the revivals of Edward’s day? 

Edward’s Faithful Narrative points to sudden deaths in the community raising serious theological questions by the people of Northampton.  Central to these questions is the nature of salvation and how one is assured of this salvation; a main dividing point between the main European theological traditions of Edward’s day.  Tied with the contemporary drive to rationalize the natural and supernatural world, one can see how a simple question of personal salvation and assurance could blossom into community-wide speculation and debate.  

Had America been less theologically diverse and had the question of personal salvation only had once answer, would the revivals of Edward’s day have been as grand?  As I ponder the question and read the material, I become more and more convinced that theological conflict is a key driver in American revivals.
