Many missionary biographies tell the stories of men and women who persevered for decades in a single context. Today, though, God seems to be moving His workforce around the globe with growing frequency. Items May Have Shifted is a collection of stories of missionaries who left everything and moved across the world to serve among the unreached-and then were rerouted, often without much warning or explanation.

Their experiences illustrate an inherent tension missionaries must maintain in our chaotic world: the commitment to go deep in difficult contexts as if it's forever and the openhandedness to accept that plans may change at any time.

You (or missionaries you care about) may be on the move by necessity or by choice. Either way, these stories remind us all that God's people are called to a flexible, responsive faithfulness, tenaciously clinging to the God of the unexpected.
