When 22-year-old John Piper worked as a surveyor between college and seminary, he read Martyn Lloyd-Jones' Studies in the Sermon on the Mount. When he became a pastor, he again benefited from another Lloyd-Jones book, Preaching and Preachers.
Then he began receiving sermons by Dr. Martyn Lloyd-Jones and "have to pause what I [was] doing because the weight of what he was saying didn't fit with what I was doing."
See the rest of what Piper has to share about Dr. Martyn Lloyd-Jones in the video below. If you are interested in purchasing or streaming Logic on Fire, the documentary John Piper is holding in his hand, click here.
