The Lord is my Shepherd.  These famous words of Psalm 23.  We are the sheep of the Shepherd.  The Gospel of John talks about hearing the voice of the stranger versus the voice of the Shepherd.  In the world we live in, there are many voices that try to lead us astray from the Shepherd, from the rest of the flock, into dangerous places.  Amidst all the other voices, amidst all the lies, how can we hear the Good Shepherd's voice?
