Paradigm Shifts...

I've been trying to figure out how to help people shift paradigms. No, I'm not talking about shifting from a modernist to post-modernist paradigm (although that might be helpful). What I'm trying to figure out is how to help God's people shift from a Christendom based view of the church and world to a post-Christendom / missional view.

Any thoughts on interim steps would be greatly appreciated.
