Luke 15:1-7New Revised Standard Version (NRSV)
The Parable of the Lost Sheep
15 Now all the tax collectors and sinners were coming near to listen to him. 2 And the Pharisees and the scribes were grumbling and saying, “This fellow welcomes sinners and eats with them.”
3 So he told them this parable: 4 “Which one of you, having a hundred sheep and losing one of them, does not leave the ninety-nine in the wilderness and go after the one that is lost until he finds it? 5 When he has found it, he lays it on his shoulders and rejoices. 6 And when he comes home, he calls together his friends and neighbors, saying to them, ‘Rejoice with me, for I have found my sheep that was lost.’ 7 Just so, I tell you, there will be more joy in heaven over one sinner who repents than over ninety-nine righteous persons who need no repentance.
