When Mathew spoke at his stepmother's funeral he said, "While we have no common blood and no matching physical characteristics, we have been grafted together by God as mother and son. I think sociologists would define us as a blended family. I prefer to think of us as a hybrid family, grafted together by God." When you graft two plants together it's a cool science experiment. When you graft two families together, the cutting and grafting can be painful, but the end result is life-giving.
