From his earliest introduction of "the new living faith," John Wesley taught that faith and holiness were irrecocably linked together. His ministry during the great non-denominational eighteenth century "Methodist" revival was based on the principle that the Holy Spirit's indwelling after the new birth must lead the believer to a more holy life.
John Wesley is recognized as the founder of Methodism. An acclaimed preacher, Wesley travelled extensively on horseback and drew large crowds for his outdoor sermons. A contemporary of William Wilberforce, Wesley was a strong voice opposing slavery in England and the United States. His influence upon modern Christianity can be seen by the large number of Methodist organizations in the Wesleyan tradition all over the world.
Clare Weakley Jr. has done a good job of collecting sermons of John Wesley have have to do with holiness. You see the Christian life is not only forgiveness and acceptance of God's work in you it is also a life of service, of work, of thankfulness for what God has done.
