Operation World? It is a book, a website and a DVD designed to help you pray for the needs of our world. Since 1964 there have been 8 editions. Over 2 million copies of the book have been sold in 9 different languages. The 2010 version is now available.
You can use a daily email system to help you to remember to pray for your fellow Christians throughout the world.
At the OW website you can sign up to receive an email to remind you to pray for a particular country each day. The email will direct you to a page with up-to-date information about the needs of the country you are praying for.
