John Wesley (1703 -1791) was an Anglican divine and theologian who, with his brother Charles Wesley and fellow cleric George Whitefield, is credited with the foundation of the evangelical movement known as Methodism. His work and writings also played a leading role in the development of the Holiness movement and Pentecostalism.Wesley was a logical thinker and expressed himself clearly, concisely and forcefully in writing. His written sermons are characterised by spiritual earnestness and simplicity. They are doctrinal but not dogmatic. His Notes on the New Testament (1755) are enlightening. Both the Sermons (about 140) and the Notes are doctrinal standards. Wesley was a fluent, powerful and effective preacher. He usually preached spontaneously and briefly, though occasionally at great length.As an organiser, a religious leader and a statesman, he was eminent. He knew how to lead and control men to achieve his purposes. He used his power, not to provoke rebellion, but to inspire love. His mission was to spread "Scriptural holiness"; his means and plans were such as Providence indicated. The course thus mapped out for him he pursued with a determination from which nothing could distract him.
