Thematic Bible: The lost sheep

And He spoke this parable to them, saying, What man of you, having a hundred sheep, and having lost one of them, does not leave the ninety and nine in the desert, and go after the lost one, until he may find it? And having found it, places it on his shoulders, rejoicing: read more.
and having come into the house, calls together the friends and neighbors, saying to them, Rejoice with me, because I have found my sheep which was lost. I say unto you that so there will be joy in heaven over one sinner that repenteth, rather than ninety and nine just persons who have not need of repentance.

What seems to you? if there may be a hundred sheep to one man, and one of them may go astray, does he not, leaving the ninety and nine, going to the mountains, seek that which has gone astray? And if it maybe that he finds it, truly I say unto you, that he rejoiceth more over it than over the ninety and nine that went not astray. So it is not the will of your Father who is in the heavens, that one of these little ones may perish.
