Matthew 18:11-13

[For the Son of Man has come to save that which was lost.] “What do you think? If any man has a hundred sheep, and one of them has gone astray, does he not leave the ninety-nine on the mountains and go and search for the one that is straying? If it turns out that he finds it, truly I say to you, he rejoices over it more than over the ninety-nine which have not gone astray.
