Teen Challenge, also known as Adult and Teen Challenge, was founded as an evangelistic outreach to drug addicts in Brooklyn, New York City. As a holistic Christian ministry with the life-changing message of the gospel, this faith-based rehabilitation program was created with the vision that God can redeem the whole person, starting on day one of the program. This unique approach has produced success rates of over 70% for those who complete the rehabilitation program. However, as Teen Challenge has grown worldwide, with over 1,400+ centers in 129 countries, some centers are now turning to secular methods in order to access government funding. As co-founder of Teen Challenge, Don Wilkerson raises a warning flag on this mission drift: the power of the Cross, which brings about a changed life, must be the priority in treating drug addiction; if the Cross is not central to the mission of any Teen Challenge center, then it is not worthy of using the name "Teen Challenge." The ministry must never lose its vision and focus in bringing men and women to Christ—through the gospel and discipleship—and stay faithful to the original mission which the founders stood upon.
