Luke 15:1-2,4-7 NLT
 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!  “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.’  In the same way, there is more joy in heaven over one lost sinner who repents and returns to God than over ninety-nine others who are righteous and haven’t strayed away!
This teaching of Jesus expresses the great love God has for each lost one. God goes after those who are lost to seek them out and bring them home.
The things that are of great value when found are greatly rejoiced in. In this case, people. We as lost sheep go our own way, oblivious to what is around us, the dangers of the things we get caught up in and just how far we are from God. He is pursuing us but we have to want him to come and rescue us.
