I guess it depends when that affection died and what had caused it. Love is complicated. It need norishment. And ability to love someone as a package-the person's value,personality and passion. Can anyone being showered with lots of affection and yet not be moved ? I believe it is possible to rekindle that passion inside someone but how much we are willing to put the effort and will we keep doing it even there is no reaction/response for a long period of time. If you love her, you will. And I am sure a woman of steel would be touched. Lord, I pray for passion in their life. A passion for something in common that they can share with you. A passion to love each other affectionately. I pray for softening of hearts. I pray that you take away any negativity and emotional hurt that steal this affection away. I pray for renewal of mind and spirit and I pray for restoration of their marriage.In Jesus Name, Amen!
