Arguing with a fool is difficult - Proverbs 29-30

29:9 "When a wise man has a controversy with a foolish man, the foolish man either rages or laughs, and there is no rest." If you have ever had to deal on a continual basis with someone who is absent a relationship with Christ and portrays their foolishness, you have a good understanding of this verse. God has given us some wisdom here to help our understanding and to remove some of the mystery as to why people go from one emotion to the next. The foolish man has no stability in his life because he has no relationship with truth. He can't, in his foolish state, find a balance and therefore stay on a given course. Instead what happens is that he might rage one time and then the next time be laughing. Foolishness is like a roller-coaster; it has no straight lines and leaves you in a constant state of highs and lows. Let's make sure we are acting in wisdom and have a connection to truth - that will give us stability. But, if you have to deal with foolishness that will be a constant ride on a roller-coaster.
