Nag the right One
The book of Proverbs talks a lot about nagging.
Better to live in a desert than with a quarrelsome and nagging wife. Proverbs 21:19
A quarrelsome wife is like the dripping of a leaky roof in a rainstorm; restraining her is like restraining the wind or grasping oil with the hand. Proverbs 27:15-16
I am not sure why we women in particular struggle with this issue. I think most of the time, we have good intentions. We just want everything to be just right, including our husbands. Whether we are reminding them to do something they promised they would do or making comments about things they are (or are not) doing that we think they should change. Or even silently nagging with our looks or our actions or reactions to certain situations, our nagging can do great harm to our marriages.
I will have been married 10 years this summer. And one thing that I am learning (of course I do not always get this right) is that there is someone I can nag, it's just not my husband. It's the Lord. In Luke 18, Jesus tells the story of the persistent widow. She went to the judge every day, pleading for justice. and her persistence paid off. Jesus said, "Don't you think God will give justice to those who cry out day and night?"
Persistence with God pays off. Persistence with your husband, could drive him further away. Am I saying that if I want my husband to remember to pick up the groceries I am going to pray about it rather than send him a text, no. But when we don't see eye to eye, when I think there is an issue that needs to be addressed (again), or I think there is a change that needs to be made, I can leave it with the Lord. I can trust that God can change his heart, or maybe change mine.
Let me give you a hypothetical situation. Let's say you feel like your husband's health is in jeopardy and he needs to lose weight. You have brought the issue up and your husband does not agree. Rather than continuing to argue about it, make looks every time he eats a snack, and comment about it to all your girlfriends. You could begin to pray about it and ask God on work on his heart.
Please don't hear me saying that I don't speak my mind in our marriage. I promise, I do plenty of that (my husband would gladly attest to that). I think it is so often the small things (those pesky little foxes) that do so much damage to a marriage.
Proverbs 31:2-3 Her husband can trust her, and she will greatly enrich his life. She brings him good, not harm, all the days of her life.
