Agree or Disagree?

“Preaching needs to be constantly adapting itself to the changing face of culture.”

Let me give a little more context:

“The message will never change, but the way we deliver it will change–yes, must change–or we will cease to be a bridge between two worlds.”

Of course an preacher that hopes to be biblical has to say, “the message will never change”. My question, however, is twofold: Do you agree that preaching needs to be constantly adapting itself? And will doing so inadvertently affect the unchanging message?

By the way the quote is from Alex Montoya–Preaching with Passion, p.138
