And he spoke this parable unto them, saying, What man of you, having a hundred sheep, if he loses one of them, does not leave the ninety and nine in the wilderness, and go after that which is lost, until he finds it? And when he has found it, he lays it on his shoulders, rejoicing. And when he comes home, he calls together his friends and neighbors, saying unto them, Rejoice with me; for I have found my sheep which was lost. I say unto you, that likewise joy shall be in heaven over one sinner that repents, more than over ninety and nine just persons, who need no repentance. (Luke 15:3-7)
