"In your anger do not sin: Do not let the sun go down while you are still angry," Ephesians 4:26
The Bible is my GPS to life. But even if you don't subscribe to my beliefs, you can't really argue with pop culture!
Don't let the sun go down on you angry.
This means, don't hold a grudge.
This does not mean that miraculously, you and your spouse will always reach a full agreement on all issues before you go to sleep (that's bordering boring!). But it does mean that before you go to sleep, you both have reached a stage whereby you are comfortable with the concept that whatever you are arguing about does not supercede your commitment to each other.
If you are Type A and argumentative like me, this is a very difficult thing to perfect.
I refer you to my other blog post - and advise you to start hammering some nails into fences. It will get you closer to the goal.
Happy New Year!
