In Christendom generally there is a growing interest in evangelism. This new interest presents a unique opportunity to the Church of God, for it has always been an essentially evangelistic movement. This rising tide is therefore a “natural” for us as a people, and it opens up before us for our immediate and urgent consideration this exciting new opportunity. This book is sent forth with the prayer that it may in some appreciable measure help to bring this tide to full flood which will result in a sweeping revival of the Spirit adequate to the needs of the ongoing work of God in his world.
