Summer 2010 the next edition of _Operation World_ will be published. It's a book, a fact-packed, thoroughly-researched guide to how to pray for every country in the world. It has sold more than 2 million copies in 10+ languages. The 6th edition had advance orders of 400,000. And WorldVenture missionaries Michael & Dawna Jaffarian are part of the Operation World team, based in England. So they're at the heart of this. Michael has worked full-time in global mission research since 1992. We could talk about the importance and practical uses of this tool, and about some of what we've found as we've studied the work of Christ and human needs globally.
