Jesus's words in John 12 are sobering: Unless a grain of wheat falls to the earth and dies, it will bear little fruit. Throughout history, God's strategy for reaching unreached peoples with the gospel has often included the suffering of his frontline heralds--the missionaries who made countless sacrifices to advance the kingdom of God. In the fifth volume of the popular The Swans Are Not Silent series, John Piper focuses on this flesh-and-blood reality of pain in the lives of William Tyndale, Adoniram Judson, and John Paton. Paying dearly to translate the Word of God, mobilize missionaries around the world, and lead the hostile to Christ, their stories illustrate how God builds his kingdom through the suffering of his servants.
