Tonight's subject is "The Secret of Praying." He who has learned how to pray has learned the greatest secret of a full and happy life. You're told in scripture that his followers said to him, "Lord, teach us to pray." He gave him a prayer (Luke 11:1). But that is not teaching man how to pray. So we're told in other passages that he told it in the form of a parable, "And he told them a parable that they ought always to pray and not lose heart." Then he told the story of persistency.
