That's why a good dose of creativity can open up opportunities for many students to hear. Kissing pillows and swapping most embarrassing stories. The right friends. A good place. It might be awhile since you gathered together like that.
Chances are it was the environment.
You were totally relaxed in a setting that jazzed you. Your friends were safe people, well sort of at least until you went to sleep. An evangelistic outreach needs to be on a turf that students know, enjoy and can make an escape from if it gets too hot. Remember, you're sharing about Jesus Christ. Your church wouldn't be the best place.
