Thematic Bible: The lost sheep

So in speaking to them he used this figure: "What man among you, if he has a hundred sheep, and loses one of them, does not leave the ninety-nine in the wilderness, and go in search of the one that is lost, until he finds it? And when he finds it, he puts it on his shoulders with joy, read more.
and when he reaches home, he calls in his friends and neighbors, and says to them, 'Congratulate me, for I have found my lost sheep!' I tell you, in just that way there will be more joy in heaven over one sinful person who repents, than over ninety-nine upright people who do not need any repentance.

What do you think? If a man has a hundred sheep and one of them strays away, will he not leave the ninety-nine on the hills, and go in search of the one that is astray? And if he happens to find it, I tell you he rejoices more over it than he does over the ninety-nine that did not stray. In just that way, it is the will of my Father in heaven that not a single one of these children be lost.
