Lucas 15

3 So He told them this parable, saying: 4 "What man among you, having a hundred sheep and losing one of them, does not abandon the ninety-nine in the wild*Notice that the 99 are left in the wild, not a sheepfold. So what happens if a wolf comes upon the 99 while the shepherd is off looking for the stray? I confess that I never liked this parable, for that reason. and go after the lost one until he finds it? 5 And upon finding it he joyfully puts it on his shoulders. 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 I say to you that likewise there will be more joy in heaven over one sinner who repents than over ninety-nine righteous ones who have no need of repentance.*If God prefers sinners, what is the point of being righteous? I suppose the point to be that no one is so righteous that they need no repentance. Since we are all sinners, we all need to repent—and when we do so, God is happy.
