This too is an anger management argument for the believer. You have been converted; you been sanctified. You haven't shown ill temper all day in dealing with the most intricate things at work. Why suddenly let fly when you come home to the family? This is completely improper. God has held you, and given you something, and worked in you, bringing about a reformation in you, and now suddenly you want to abandon it.
Our anger is against Satan and his legion of fallen demons and their temptations and suggestion. We are fighting a spiritual battle. Our anger is with ourselves and our sin, not with the people around us: colleagues and the people we love. That's an anger management argument to address to ourselves.
When you are looking for a wife – or husband, come to that – you are looking for somebody whose chief concern is the work of the Lord. Not necessarily that he is going to be an evangelist or a missionary or a minister full-time, but he is a Christian. What sort of a Christian? A nominal believer, a weak Christian, or an authentic Christian: one whose greatest concern is the cause? Which church you go to, what you do for the Lord, how involved you are; these are the things to talk about. Not movies, not other people constantly, but the cause and the exploits of the King of kings. It's the king's business all the way, and so it is with her. As she proceeds she is talking about his commission: ‘Oh David, you are anointed to be king; I know it. May all your energies be for your commission from the Lord, not with a worthless Israelite like Nabal.’ She understands that David is anointed by the Lord, that it is God's purpose that he will ultimately be king. She has insight, spiritual insight, and these are the things that matter to her. That is the sort of person you want, whether in a wife or in a husband: someone who has priorities.
