Operation World is the most important missions book available today. It is an absolutely indispensible part of any missionary’s library.
Yet when Patrick Johnstone first approached a major Christian publisher, his manuscript was rejected as “unmarketable!”
Now, mission leaders from around the world are united in affirming Operation World as the most important, useful and influential missionary book available. Millions of copies have been printed of the 7 editions of Operation Worldand they have been translated into 15 different languages. Multiple editions have been published in German, French, Spanish, Portuguese and Korean. At this time translation work is also underway in Arabic.
