3 Then Jesus told them this parable: 4 "Suppose one of you has a hundred sheep and loses one of them. Doesn't he leave the ninety-nine in the open country and go after the lost sheep until he finds it? 5 And when he finds it, he joyfully puts it on his shoulders 6 and goes home. Then he calls his friends and neighbors together and says, 'Rejoice with me; I have found my lost sheep.' 7 I tell you that in the same way there will be more rejoicing in heaven over one sinner who repents than over ninety-nine righteous persons who do not need to repent.
I always had problems with that one. What happens if after he's left the 99 one or more stray, or are stolen, or are killed by wolves?
