During his ministry, which included extended pastorates in Chicago and Toronto, Dr. Tozer was often referred to as a prophet. That doesn't mean he predicted future events, but rather he spoke God's truth to believers and the culture, even if it meant disrupting the status quo. Even in the Bible, prophets were much more likely to hold God's people and their leaders accountable to the truth of God's Word than to foretell the future. The encouragement in Voice of a Prophet is that the church today is in desperate need of the kind of prophet Tozer embodied and describes in this important book. Using the lives of such prophets as Elijah, Elisha, and John the Baptist, Tozer underscores the importance of the ministry of the prophet in our world today.
