Many things have been written and said about John Wesley. Not all of them have been complimentary. Indeed, many angry words have been used to describe the Wesley brothers and their group of Methodist preachers.
However, few can deny that one of the things that John Wesley did most effectively was teach people how to work together. British Wesley historian Robert Wearmouth refers to Wesley’s greatest achievement as “collective activity.” With all its discipline, self-control and even self-sacrifice, Methodism has taught the value of group dynamics. It’s a characteristic we experience each year at Annual Conference
    Wesley's followers were organized into groups called “bands,” which came together in “classes.” The classes came together in “societies,” and the societies came together in “circuits,” which in turn were grouped into “districts.” All the districts came into one whole, called the “conference.”
The “Connexion” includes Wesleyans around the world. The Connexion makes the whole enterprise work for service to society and the glory of God.
    Just as the people have been “connected” effectively to each other, Wesley established geographical bases to connect his work in England. He established solid bases in the four corners of England: London, Bristol, Newcastle and Cornwall.
He would spend his years traveling from one base to another, preaching in the societies and tending to the needs of the poor wherever he found them. Those four bases were located strategically to provide a structure for Wesley’s travels and to enable him to preach and minister to the largest numbers in the most efficient manner available.
    As he did so often, Charles Wesley summed up John Wesley’s message and manner with a few succinct lyrics: 

He bids us build each other up;
    And, gathered into one,
To our high calling’s glorious hope
    We hand in hand go on.
