The first big issue has to do with the fit of your gifting and calling within any particular mission. If God has called you to Tahiti (don’t you wish!), you had better make sure that any mission you are thinking about actually works in Tahiti. If God has called you to a place where there is nobody working, then you need to find a mission that is willing to support you in that. WEC is very open to working in new places, but generally we want to see a team of people going, with enough experience on board to keep the ship steered in the right direction.
