Playing the trump card

From an article about Child of Divorce, Child of God on the Christian Grandparenting Network web site:

If you have ever played a card game involving the use of a "trump" card or suit, you know the frustration of playing what you think is a winning hand only to have it trumped by someone else. Now is the time for Christians to play our "trump card" -- our belief in an all powerful and loving God...As grandparents, we know all about the ravages of divorce, even as Christians. If you are living with the reality of divorce in your family, this is a place where "intentionality" is crucial. We are in a unique position to help our grandchildren of divorce find healing and hope. But it means we must build a solid framework of truth about the God who IS, and that He really does care about the burdens and wounds they bear.
