In this book, Lewis Sperry Chafer instructs the aspiring preacher on the authentic principles of evangelism: that salvation, and proper communication of Christ's message, are of utmost importance. Chafer begins by noting the emergence of preachers who behave and speak contrary to the wishes of Jesus Christ. It is these 'False Forces' that moved the author to spell out precisely what is and is not true evangelic preaching. The identification of falsehoods in the messages delivered, and improper emphases which distract from the ever-present, ever-beneficent God, led Lewis Sperry Chafer to pen this book. Lewis Sperry Chafer spent a lifetime in evangelical preaching and writing in service of the Lord. Although remembered mainly for his scholarly work upon Biblical theology, he was also praised for his easygoing and relaxed demeanor. His leadership at the Dallas Theological Seminary was characterized by this competent, just and thoroughly Christian personality.
