Advent is a season of hope, and comes with new grace to renew us in our hope. Without hope, we do not have direction in our lives; without hope, we die. The great symbol of this in the Scriptures is the figure of the Watchman. The Watchman can continue watching because he knows that finally, God is the one who watches over Israel - and when all else has failed, we can still stay awake because the One who watches over us never gives up.
