The contrast between the lost and the found condition of the one sheep was the cause for the shepherd"s great rejoicing. His joy at the secure condition of the sheep is the point of the parable. The parable also pictures the shepherd (Jesus) taking the initiative in seeking the lost, a major theme in Luke (cf. Luke 19:10; et al.). By picturing the shepherd carrying the sheep home on his shoulders Jesus was communicating His loving care of those He saves. His action depicted common rural practice. [source][source][source]
