God actively engages in evangelism — the Church should too. The nature of the Gospel and the scope of grace should compel the Church to preach beyond itself, yet Mackintosh observes that many evangelists abandon their work. Why do evangelists pursue other interests? Why do evangelistic efforts languish? Most importantly, how can they be revived?
Each chapter in Papers on Evangelization contains a brief exposition of a key text on evangelism, along with Mackintosh’s advice and encouragement. He reminds evangelists of the urgency of their task and the nature of their calling. Fittingly, in same vein as the New Testament epistles between Paul and Timothy, the second half of Papers on Evangelization is devoted to correspondence between Mackintosh and an unnamed evangelist.
