In some circles public evangelism has fallen out of favor. Many churches are daunted by the prospects of reaching the unchurched out in the open, beyond the walls of their sanctuaries. And many Christians assume that the days of mass public evangelism have passed and instead rely on outreach through private, individual efforts. But the gospel of Jesus Christ has always been a matter of public proclamation. From the earliest days of the church, in every age, the growth of Christianity has been tied to the public preaching of the good news. In this landmark book, evangelists Lon Allison and Mark Anderson issue a stirring call for the revival of public gospel proclamation. They show how God has used evangelistic preaching in the past and how it can be practiced with relevance and effectiveness today. Recovering public proclamation, they argue, is key to the vitality and ongoing mission of the church. An essential resource for evangelistically minded Christians from the local church to specialists in international missions organizations, this guide offers hope that Christianity can again reach the masses in the public square.
