One of the most famous and influential preachers of the gospel in US history was D. L. Moody. The preacher, who lived in the 19th century, also founded Moody Bible Institute and began publishing Christian books—scarce at the time. Both MBI and Moody Publishers continue to function more than a century after his death. Surely such a renowned believer in Jesus was highly trained and educated! But that doesn’t describe Moody. He had very little education and worked as a humble shoe salesman for years before his conversion.
