The correct answer to this open question is the following.
In the account given by Benjamin Franklin of his experience of George Whitfield preaching, what is made clear is that George Whitfield was an extraordinary preacher and an orator that had the skill to address a multitude of people and convince them about his messages.
In 1739, Franklin writes that first, he had been granted permission to talk in the churches, but then he had to go outside, on the fields. Due to the inclemencies of the weather in Philadelphia, supporters collected money to build a big construction so any preacher could gather people and evangelize. George Whitfield attracted hundreds of people and his messages moved them.
