What I think this song means is that Neil is saying he has been overwhelmed with grief over the loss of his wife and daughter. I think the first verse says he was there and then he was swept away. He didn't have a choice or any control so he was swept away. The sweet miracle is his wife and daughter whom he missis very much and wishes they could be with him now. The second verse where he says he is raging against the night I think is about the feeling of being alone. I think the salvation is and further the miracle is also the will to go on with life. So in essence the song is about death of loved ones and missing them greatly, but forgiving yourself for still being alive and going on with life.
