Words mean things. All words. To the author, and the audience, whether the later is the intended one or not. Just because we are surrounded by words, many of them banal, many of them profane, does not give us excuse for thinking any of them are without meaning. All of them are a window into the author's heart and mind.
To claim that words may be without meaning, or that we cannot know their meaning is not only illogical, but I would submit, is also heresy, and quite possibly even blasphemy.
We should pay attention to our words, the words of others, and the Word of God.
