Dan Kimball is one of the leading thinkers and voices of the ideas and thoughts behind the emerging church. I've read a couple of his books and they have challenged my thinking considerably.
This past week I finally sat down and read his notes from a workshop that he taught at the Youth Specialties Youth Workers Convention in 2002. His notes from this workshop contain perhaps one of the best explanations of postmodernism and how it has evolved into the everyday thinking of our culture.
If you're not familiar with the term "postmodern" or aren't sure what it really means, download it and read it. The church cannot remain ignorant on what is happening in our current (and future) culture. This is a necessary read for anyone (staff and volunteers) in church ministry.
