I received this email tonight, and thought that it was too excellent to not respond to and then repost here. Hope it's helpful:
1. It is true that some people, through winsomeness and tactics, are more effective at evangelism than others.
2. It is true that the person being saved has absolutely nothing to do with the process; It is 100% God "flipping the switch" so to speak.
How do you resolve the contradiction between these two beliefs? If becoming a Christian has nothing to do with the person being saved and how much they appreciate the evangelists' tactics and winsomeness then how can those same attributes make the evangelist more effective?
Those attributes should only be effective when you are trying to convince someone of something that they themselves have some role in when it comes to the decision process. A winsome car salesman with finely tuned tactics will be more effective at getting the consumer to make a certain decision but that's because it's a decision that that consumer is involved in. If the consumer had absolutely no say in the matter then the salesman's winsomeness and tactics would be irrelevant; A poor salesman would be just as effective.
