The Holy Spirit

This article did well to bring up to the forefront the idea of religious rhetoric. Reverend Cantrell was pictured as a master of words, effectively using adverbs, metaphors, and allusions together. By weaving together his personal narrative, the Word, and, slowly establishing Susan as the listener he was able to infuse the ideas of born-again Christianity into Susan. What I have a question of is the Holy Spirits role. If left without the addition of the Holy Spirit Cantrell could be likened to a demagogue. He could simply be seen as a person with the ability to craft language well enough to convince people of almost anything. In the article it says that the "Holy Spirit uses Reverend Cantrell's speech" to "remodel his listener's inner speech". Does this mean the communication is happening through the Spirit and not the Reverend himself? Or is it the Spirit that allows the words of the Reverend to be taken to heart? What is interesting to understand is the relationship between the Holy Spirit and the non-believer, because to not believe seems to suggest that the Holy Spirit cannot interact with you, yet there must be something to bridge the gap (whether that be the preacher, or other elements). Yet if the preacher is the one bridging the gap, and he/she is a manifestation of the Holy Spirit, then is there any gap bridged at all?
