Shepherds heard an announcement that priests and kings would have loved to have heard.  “God has chosen the foolish things of the world to shame the wise, and God has chosen the weak things of the world to shame the things which are strong” 1 Cor 1:26-29 (NASB).  God makes the nobodies of the world receivers and bearers of the greatest story ever told.  Be as the shepherds, do not let the story stop with you!
