The story of King David, which is the story of Jesus Christ, which is the story of the salvation of all humanity, begins with the story of Samuel; and the story of Samuel begins with the story of one unhappy, unlucky person named Hannah, who prayed to the Lord for her dearest desire; and, when she finally got it, gave it up out of gratitude for the God who heard her heart's wordless cry.
God? I'm just sayin'.
