"The Call of God in Jesus Christ for Holiness and Social Morality: Fifteen Textual Sermons on the Lent with Methodist Piety and Social Morality or Scriptural Holiness of Methodism," is to explain how the biblical concept of holiness differs from the concepts of holiness of other religions and why biblical holiness must be expressed through social morality or justice. Rev. John Wesley and Rev. Charles Wesley emphasised on holiness and social morality when they established the Methodist Church in Britain and North America. The biblical concepts of holiness and social morality are applicable to all Christians, irrespective of their denominations. An observance of the Lent season calls all Christians to walk in holiness and maintain social morality.
