Of course, because life is never simple, we must acknowledge that there is a type of harsh language which dishonors God and embitters our neighbor. And we also know that there is a type of soft answer which turns away wrath. We know that many cantankerous Christians have defended their sin in the guise of Valiant-for-Truth. Far from trying to smooth these words into an easy fit for us, we must take them as they come, and simply submit to them. There are certain kinds of hard words which belong to the devil, and our speech should always be gracious and seasoned with salt.
