"Here are a few ways you can encourage students to share, although I bet you can get with them and come up with creative ideas of your own. * Post their testimony as a Facebook note or on their blog or Tumblr, and link to that with Twitter or status updates. Or, send a message to friends and ask them to read it and give their feedback. * Tweet or post key verses, maybe a series noting the narrative of the gospel. * Set aside an hour a week online just for the gospel, like "virtual visitation" where they take that time to talk to a friend about Christ."
