Family

I am in desprate need of prayer. We are alienated grandparents. Four years ago my son and daughter-in-law decided to shun us, for lack of a better word. We have never been told why except that they need to protect the family from us. Of course we questioned, begged and pleaded and tryed to guess. To know avail. They claim to be Christians. Prior to this we were the main care providers for eight years while they both built their businesses. There was no abuse. Physical or sexual. We even asked my son if he thought we had. He laughed and said absolutely not. This is a horrible spiritual battle. We miss our grandchildren desperately and it has taken a horrible toll on our family. Please help us pray.
