Jonathan Edwards's Evangelism - The Charge of Preparationism Critiqued

A study of the evangelistic method of Jonathan Edwards in such sermons as Pressing Into Kingdom, God Makes Men Sensible of Their Misery, Tne Manner in which Salvation is to be Sought. Why was there an appeal to mercenary motives? Were the applications what is sometimes labeled "preparationism" in fact so? Was Edwards alone in his instructions to the unconverted sinner, or did this in fact follow the Puritan Tradition? Why has modern evangelism shunned the type of awakening illustrated in Christian in his awakening detailed in the allegory Pilgrim's Progress?
