Does God have the capacity to make an untrained missionary effective? He certainly can, and He occasionally does. But the facts show that missionary longevity and effectiveness are much more likely for the person who has expended the relatively minimal amount of money and time to be as prepared as possible for success on the field with pre-field training.
The importance of pre-field missioanry training can not be overemphasized. In this podcast we interview Brian Gibson, a former church planter in a Muslim context setting who has since taken the lead at our partner ministry, Train International.
