John Knox ranks among the great leaders of the Reformed tradition. In particular, he made significant contributions to this movement as it unfolded in Scotland. In doing so, Knox wore many hats--prophet, pastor, preacher, reformer, statesman, revolutionary, and more. God's Watchman: John Knox's Faith and Vocation attempts to connect these aspects of Knox's life. Being a man of action, these roles come to the forefront. Still, they rest on a particular faith shaped by his interpretation of Scripture, his view of God, and the events of sixteenth-century Europe. Section one of this study establishes these beliefs. Part two spells out his vocation--namely, functioning as a prophet, pastor, and preacher. All of this--his faith and vocation--culminated in his revolutionary political ideas, which are the subject of section three.
