And is it any wonder, if you think about it. Most of the times that we get really angry, it is because something false has been accused, or we have been wrongly faulted. Even the best of saints gets angry when that happens. A little less falsehood would lead to a little less wrath. In exchange we are to speak truthfully to our neighbor.
Christians are held to higher standards, that is true.
We are not allowed to sink into the depths of flattery or untruth in speech. We are called by God to speak the truth to one another, and to do it lovingly. So our speech is one crucial area to monitor if we wish to reduce wrath. Don't forget that speech is a godly preventative for anger. While we're in that section, look on down to v. 30 to note another part of the environment surrounding the commands.
