John Wesley, a famous preacher in the 1700s, preached the whole gospel in just 4 points. He created a movement, and from that, many movements that last to this day.
These 4 points is what he taught all his helpers. That is what they preached. It has a lot of power today for everyone.
It is particularly important for us, who are reconsidering sonship doctrine because he was the first person to preach sinless perfection. The holiness movements came out of the Wesleyan movements. To build well, it is a good idea to understand the foundations.

Here is a movie on John Wesley, that will give you a good feel for him and his work. What they portray about his time in Georgia with the girl is very uncertain. Most probably it is souped up for movie purposes. https://www.imdb.com/title/tt1053946/
