I'm sure that you can think of a time when your grandparent told you something that changed you. I can remember lots of great lessons about life from my grandmother and many of them she never spoke. Let me first say that I adore my grandmother. She is the most amazing wife/mother/grandmother that I know. I believe that the reason for success in her marriage is her tremendous respect for my grandfather.
My grandmother has always ironed all of my grandfather's clothes even his handkerchiefs. The funny part is that he is a cotton farmer and works in the field on a tractor. I have never really understood that, but that is just how it has always been. Once I asked her if she ever got tired of always ironing his work clothes. She told me that when she ironed his shirt, she would think of how strong he was. She would think about how blessed she was to have a strong husband that could work and take care of her. She would think of his shoulders and how she liked to lean on him. She would work down the shirt thinking about her blessings as a wife and about how much she adored him. I have never ironed the same since (of course I rarely iron - dry cleaning). I think the point is that she chose not to see this as a chore, but as a way to reflect on him and count her blessings. I have NEVER heard my grandmother say an unkind word about my grandfather. I have NEVER seen her show him disrespect. And I have seen the way that he loves her by the way he looks at her. That is exactly the way a "Godly marriage" should look!
