For 30+ years, Dr. Lloyd-Jones ministered at Westminster Chapel in London and is widely considered one of the greatest preachers of the 20th century. This is a series of lectures originally given by him to the students of Westminster Seminary in 1969 on the essence of powerful preaching. Lloyd-Jones challenges preachers to take their calling seriously, provides practical direction for preparing sermons, sharing insights on the shape and form of a message as well as covering such topics as the use of humor, giving invitations in a message and the preacher’s relationship to the congregation.
