Tax collectors and other notorious sinners often came to listen to Jesus teach. This made the Pharisees and teachers of religious law complain that he was associating with such sinful people—even eating with them!
So Jesus told them this story: “If a man has a hundred sheep and one of them gets lost, what will he do? Won’t he leave the ninety-nine others in the wilderness and go to search for the one that is lost until he finds it? And when he has found it, he will joyfully carry it home on his shoulders. When he arrives, he will call together his friends and neighbors, saying, ‘Rejoice with me because I have found my lost sheep.’
