This book examines the biblical principles and modern techniques of effective evangelism. It emphasizes how God is working through His people today. Examples from many countries show how basic evangelism methods can be used in a variety of ways. The biblical teaching on sin and salvation is given as an essential part of the training in how to share the message. Methods of personal and mass evangelism point out ways in which all Christians in a local church can work together to evangelize their world. 264 pages.
