Teens will often care about the subject matter when they see that it matters in real life, that it made a difference in the life of someone they know. Can you think of a time in your life when God was not the sole focus of your life? Would you feel comfortable sharing what your life was like when there was not a “place” for God?
Avoid generalizations, if possible. Think of a tangible difference that making a place for God in your life has made. Mind you, there’s no need to reveal some deep dark secret here.
