Luke 15:3-7

And he spake unto them this simile, saying, ‘What man of you having a hundred sheep, and having lost one out of them, doth not leave behind the ninety-nine in the wilderness, and go on after the lost one, till he may find it? and having found, he doth lay [it] on his shoulders rejoicing, and having come to the house, he doth call together the friends and the neighbours, saying to them, Rejoice with me, because I found my sheep — the lost one. ‘I say to you, that so joy shall be in the heaven over one sinner reforming, rather than over ninety-nine righteous men, who have no need of reformation.
