Every local church should be engaged with global missions, even if most individuals in the church aren't called to go overseas. But what does this engagement actually look like? How can local churches train, send, and support missionaries well? Unpacking principles from the Bible and applying them in the context of real life in a local church, this book in the 9Marks: Building Healthy Churches series is filled with practical steps and advice for supporting missionaries, forming international partnerships, sending short-term teams, and engaging with the nations here at home. This book casts a vision for the local church as the engine of world missions―for the joy of all people and the glory of God.
