Now all the tax collectors and sinners were coming near to listen to him. 2And the Pharisees and the scribes were grumbling and saying, “This fellow welcomes sinners and eats with them.” 3So 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? 5When he has found it, he lays it on his shoulders and rejoices. 6And 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.’ 7Just 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. (Luke 15:1-7, NRSV)
How many of us if we had 100 sheep and discovered that 1 of them was missing would leave the 99 in search of the 1?
Maybe if they were in a barn or a pen, then yes, but if they are in the wilderness and not protected then probably not. But here the shepherd leaves the 99 in the wilderness and go after the 1 to find it. That is how extravagant the love of God is for you.
God loves you so much that God leaves the community to watch each other as God finds those who are lost.
This is not about the sheep repenting and returning it is about the love of God who goes searching.
