The unsaved, backsliders, etc. need an evangelist. Teams will be sent to the streets, parks, nursing homes, churches, etc.
Every staff member has extensive experience in reaching the lost. Every student will benefit from their experience.
Street preaching is a lot of fun. After you preach, you look for people who are looking at you but to shy to approach. Then it is time to evangelize one on one.
Passing out Bible tracts is another great form of evangelism.
