Lord, You know where this mom is and why she has abandond her children. What a great burden for this grandmother. Not just the physical demand but the emotional duress as well. Give this grandma peace and heal these children from this pain their mother is causing them. Keep these children from suffering the conquesences of their mothers actions. Let not the sins of the parents visit these children. Let them know their grandmas great love for them. Rehabilate this mom before it is too late for her to have a wonderful relationship with her children. Before they have been damaged emotionally and physically. Help this grandma to exercise tough love to her daughter. In Jesus name I pray.
