In John 10, Jesus draws the analogy between sheep following the voice of their shepherd and us following His voice.  If only I was as faithful as a sheep!!
When flocks would mingle together at a watering hole it would be hard for the casual observer to tell one sheep from another.  I wonder if this is how I look when I am out in the world – is it hard to identify me as a follower of the Good Shepherd?  Do I look and act like all the other sheep who belong to other shepherds?
When the shepherd would call out, his sheep and only his sheep would leave the watering hole and come to him.  They knew his voice alone and wouldn’t follow another.  Over time he had guided and protected them – trust had been established.  A relationship of exclusivity had been formed.
I know the Good Shepherd’s voice.  Through study, prayer, and other means I am trying to know His voice better.  But at times I hear other voices.  At time I even listen to and follow the voices of pride, control, and judging – just to name a few.  And then very soon I hear the voice of the Good Shepherd, the Holy Spirit, calling my name and drawing me back.  Sometimes He has to shout.  Alas, I am still a work in progress.  But He knows my name and keeps calling.  And I hear His voice.

Ponder how you hear His voice and what you can do to hear it better.
