Believers vs. disciples

I've been reading "The Irresistible Revolution" by Shane Claiborne. He tells the story of his struggle and growth as a disciple of Christ. He kicks my butt. I am asking the question, "Am I helping to create believers or disciples in our youth ministry?" Yes, I do see a difference. I've heard it said that Satan himself believes in Christ, he just doesn't follow him. Being a believer isn't good enough. I fear that I have helped teens to grow into believers that wouldn't describe themselves as followers. I need to be leading teens into action, not only belief. Disciples are followers who believe, too.
