Question about Missionary Training for missionaries:
"How should I get evangelism training?"
The best way to learn would be to find a group or individual that is doing what you hope to do and then ask for an internship opportunity. This would help you learn how to be effective in evangelism in the context in which you desire to serve.
Training for Trainers is a very simple system designed for laymen to train other laymen to train other laymen and so on. The approach is incredibly simple, but not easy. Check out the website for more information.
