This article details the great preacher John Wesley's vision that all Christians not only need to be personally holy, but that holiness also included social holiness. The United Methodist Church which was founded upon these beliefs, practiced social concerns in regards to slavery and other issues which affected the people of that day and age. John Wesley also diverted a possible civil war by preaching the gospel to the peasant class, which thereby turned their hearts to God, and they did not revolt.
