Four Spititual Circles?

A while ago I read an interview with James Choung (here it is). In it he explains how he came to use four circles to explain the gospel to our current culture that is interested in social justice. Part 1 of a brief video is here; part 2 is here. I think it is a good tool that is more relevant than "The Four Spiritual Laws," though that can be useful too. I suggest reading the interview before watching the video.
