Along with his brother Charles, the great hymnist whose music was a key attraction for many to the movement, Wesley did much to save England from the social convulsions that came later in France. Tens of thousands of persons became connected with the Methodist societies before John Wesley died. In America, they began to grow rapidly from the time Methodism started. Methodism was revolutionary in its conception of religious principles. In the Church of England, salvation was theoretically a spiritual process to be secured through worship and the sacraments of the Church. The evangelical preaching of Wesley called for definite repentance of sin, wrestling with God for forgiveness, and an experience of peace and assurance. Feeling and volition were stressed more than intellectual assent and conformity to ecclesiastical custom. Directly and indirectly, the Methodists contributed to the missionary and humanitarian enterprises of the nineteenth century.
