Diversity

I am doing a panel presentation on the gift of diversity in the church on Saturday, May 22.  Inasmuch as I am a passionate advocate for diversity, I am often distressed by these types of conferences because it seems that we are always preaching to the choir.  The people that attend them are already in favor of diversity in the church and so no hearts are being changed.  How can we have diversity of thought at a diversity conference?  That is the question.
