Here is a good quote from Mark Driscoll‘s book ‘Confessions of a Reformission Rev.’;
“Being cool, having good music, understanding postmodern epistemology, and welcoming all kinds of strange people into the church is essentially worthless if at the bedrock of the church anything other than a rigorous Jesus centered biblical theology guides the mission of the church.” (Confessions of a Reformission Rev.; page 78)
