He who brings trouble on his family will inherit only wind, and the fool will be servant to the wise. Proverbs 11:29
One would think that shooting yourself in the foot would be something that most people would be against, but time after time, we see it in families and friends. Someone in the family will have self-destructive behavior that affects the entire family. Alcohol abuse comes to mind. Violent anger is another.
Almost without fail, you probably know someone in either of those two abusive situations. Pray for them. Pray for their families. And pray that the person who is abusive.
