Every fundamental church has a urgent need to train soul winners are train more soul winners.  

Fairs and Festivals offer many occasions to train and mature soul winners.
Hundreds and sometimes thousands of prospects flow through an event daily.  A soul winner can take a trainee to hear, watch and experience the joy of winning and warning the lost. 

A journeyman soul winner can tutor an apprentice in just an afternoon, even crafting a trainee into a trainer, because of the great number of opportunities.

2 Tim 2:2  "And the things that thou hast heard of me among many witnesses, the same commit thou to faithful men, who shall be able to teach others also."
