Lead short-term mission trips (STMs) that catalyze trip participants into mission-oriented disciple-makers when they return home. STMs can be mutually beneficial service opportunities that have positive long-term impact on both trip participants and national hosts. While this is possible, it is not always the outcome of many STMs. STMs often prioritize the short-term experience of trip participants and miss the longer-term discipleship opportunity they offer. STMs can be a context of significant, mutually beneficial work between both trip participants and national hosts. This work can serve as a catalyst for meaningful, long-term growth for both parties, but an appropriate philosophy and trip structure is needed. This book studies and reveals best practices for both.
