Matthew 18:12-14

12“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?

13And 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.

14So it is not the will of your Father who is in heaven that one of these little ones be lost.
