Quarreling with "the real world"

Will Willimon tells the story of a man who accused him of not keeping his sermons "close to the real world":

Where did he get the idea that a preacher ought to defer to "my world"? Most good sermons have a quarrel with popular definitions of "the real world." I ought not simply to address the world where people currently reside. Rather, I ought to move their citizenship to a new world.

Amen. Preaching not only conveys ideas and emotions; the Word of God shapes us and prepares us to think and act with the mind of Christ.
