Logic on Fire: The Life and Legacy of Dr. Martyn Lloyd-Jones is the official documentary feature film of a man widely recognized as one of the greatest preachers of 20th century. While many may know the name Martyn Lloyd-Jones, fewer know the man himself and what defined his ministry. Following Lloyd-Jones’ remarkable story from his upbringing in rural Wales to his medical training to his conversion and call to the ministry, Logic on Fire examines the way he sought a union of “logic” and “fire” in preaching and how his humble dependence upon God for the work of the ministry is a model for contemporary evangelicalism.
