I also read the story of a group of eastern shepherds who had gathered around to separate their sheep from a consolidated flock. A stranger asked if he could try it and the shepherds agreed. None of the sheep moved. It only happens when the sheep is very sick. The sheep know the shepherd and the shepherd knows the voice of the shepherd.
Sheep don t follow a false shepherd unless they re sick.
Often a false shepherd entering the flock will cause pandemonium among the sheep. Jesus is the Good Shepherd of the flock. There is no doubt whatsoever that the Good Shepherd knows his flock you and I individually. He knows us better than we sometimes wish he did. One wonders if we sometimes recognize his voice within the church itself.
