Matthew 18:11-13

[For the Son of Man has come to save that which was lost.] “What do you think? If a man has a hundred sheep, and one of them gets lost, will he not leave the ninety-nine on the mountain and go in search of the one that is lost? [Luke 15:4-7] And if it turns out that he finds it, I assure you and most solemnly say to you, he rejoices over it more than over the ninety-nine that did not get lost.
