I was reminded recently that we work with hurting teens. Self-harm, suicidal thoughts, and depression are all parts of the calling we've entered into. While we can't solve all of their problems, one our youth workers utilizes a "Contract for Life" with those who we can help them, once the immediate danger, has passed. Feel free to adapt this resource for your ministry.
This is a great tool to covenant with your students and clarify the communication between yourself, their small group leader(s), and the student. Fill in the appropriate blanks and make copies for everyone. This covenant is a great opportunity to remind your students that they are loved children of God and they are loved and cared for in your youth ministry.
