The advanced missionary training course of BBTI is of such an intensive nature that it is not feasible for students to have outside employment. Since the missionary will be working full time on the mission field, it is essential that such full time service begin during training.
The missionary in training begins learning how to trust God to meet his financial needs now while he is in his own country. Students are encouraged to arrange weekend deputation meetings. This provides some income and often results in life long friends and churches who take on a part of the prayer and financial support of missionaries.
