Find Mission Opportunities
ShortTermMissions.com helps people quickly connect with short-term mission trips that fit their gifts, calling, and availability, listing hundreds of mission trip provided by many agencies.
Mission Finder lists hundreds of short term, medical, domestic, and international mission trips, categorized by location and type of ministry. Lots of links, short descriptions.
Missions-trip.com is similar to ShortTermMissions.com and MissionFinder.org. It has long-term Christian mission opportunities as well as short-term ones.
Finishers Project is designed for adults of middle age and older (Baby Boomers). The same ministry provides MissionExplore, for younger adults and organized around causes, and Mission:TEACH, placing teachers in international Christian schools.
ChristianJobs.com is not specifically focused on missions opportunities, but lists options for employment at ministry organizations, nonprofits, and Christian businesses.
Don't forget that some mission agencies list specific opportunities right on their websites. Others would be happy to tell you about specific ways to serve with them if you contact them by phone or email. Ask mission agencies about short-term and long-term opportunities. Don't overlook what are sometimes called "mid-term" opportunities, those which last for from several months up to a year or two. Sometimes these are not advertised, but they may provide the best way to get to know an agency while being further equipped for a lifetime of ministry.
