Teaching Paradox to Teens

I'm teaching the senior high sunday school class next week, and I would like to teach about the Lutheran paradoxes (sinner/saint, two kingdoms, law/gospel, justification by grace through faith, theology of the cross).  Obviously these paradoxes each merit their own session or two, but I would like to simply introduce the concept of Lutheran paradoxes because I find them to be:

1. a window into Lutheran theology;
2. a description of the Christian life; and
3. a comforting contrast to the dominant black & white, moralistic, do-it-myself theology operative in much of American Christianity.

Any ideas on how I can illustrate paradox with an activty, game, music, DVD clip, etc?  I know the lesson content, but I want to make the lesson interesting and enaging, not just a dry delivery of doctrine . . .
