Proverbs 18 mentions the speech of an individual a great deal. Keep in mind as you encounter this that the words which come out reflect what is inside. That is why the words matter: Solomon is not saying to get the words right. He is saying be right so that the words follow.
Proverbs 18:9 would be a great one to post at work. The one who is a slacker, who does not do what should be done? They are related to the one who just goes about destroying. That course you just kind of punted, that work day you did nothing and coasted on someone else? That’s right beside destruction. Probably shouldn’t do that, should we?
Proverbs 18:19 falls on the list of “Proverbs for Blogging” that we Christians ought to be well aware of. Arguments among brothers, sisters, close companions can be deadly to a relationship, and when that hits, it is hard to restore. How hard?
It’ll take a miracle.
