Evangelism, or the preaching of the Christian Gospel to convert people to Christ, has more ways to be effective today than ever before, thanks to the mass media of communication, radio, television, newspapers, advertising, etc. But since a large part of the Christian life is that which is nourished within a fellowship, the local Christian community or Church, remains now as it was in the beginning, the most important instrument of evangelism available. Often become complacent and smug the fact is that its revival and more effective use of its resources remains the main source of growth and outreach of the Christian Gospel. The author describes therefore, the evangelistic church, the evangelistic pastor, the preaching mission, lay and youth evangelism, personal evangelism, and many other aspects of the proper work of every Christian in every Christian Church. Both Protestant clergy and laymen who take their task seriously will profit from this book.
