Soul, from Christianity Explored, is perfect for introducing Jesus to older teenagers and young adults (14 yrs+). It features a range of activities, talks and Bible studies to communicate the gospel in an accessible and relevant way. The Soul course comprises a Leader's Guide for those running the course, a Handbook for the course participants and a superbly produced DVD.
See the author and presenter, Nate Morgan Locke, talk in detail about the course.
For 11-14 year olds, there is the CY course.
