One of my all-time favorite sermons EVER, from one of my asbolute favorite preachers is available from the link below. Paul Sain is doing a great service to make these Voices from the Past come alive in this 21st Century! Bobby Duncan uses an illustration about obedience from the pioneer preachers (even mentions Kentucky), in this lesson which has two vital qualities: (1) simplicity; (2) power! You should listen immediately and share it with others. Go to the Voices from the Past Podcast site.
