In the Parable of the Good Shepherd (Or Parable of the Lost Sheep) the Pharisees come face to face with the prophesy of Ezekiel, they have failed as the shepherds go intended them to be and through their religion, have neglected the lost sheep.  The main point of the parable is that God loves his sheep and only through the good shepherd (Jesus) will the lost sheep be found and there will be great joy in heaven. Luke 15:1-7, Ezekiel 34, John 10:1-18, Matthew 18:10-14
