Most missionaries who are preparing to work cross-culturally have little experience in that culture. It is best if the person has some overseas experience prior to moving long term, but it is a reasonable risk that churches should cautiously take. That’s not what I’m talking about here.
I’m talking about the person who has not proven himself in the USA in the job that he intends to do overseas. For example, if he is a church planter, has he ever planted a church? If he is to be an evangelist, it is evident from his ministry here that he has that gift? If he is to create a ministry among university students, has he ever started a student group? These tasks are more difficult in a new culture; if he doesn’t have experience here, it is likely that he won’t be able to do the ministry there.
What should we do?
There is no job description called missionary. If someone says he or she is going to be a missionary, probe to find out exactly what he is intending to do. If possible, get a written job description. Then ask about the fruit that the person has seen in his ministry in the USA. If there isn’t much fruit, it is probably better if the person waits to get more experience before going overseas. If he doesn’t have a job description, you should let him know that you can’t fund job with no job description.
Stewarding the financial resources is an important role in your church, avoid the error of funding missionaries with no experience in the job they want to do.
