Matthew 18:10-13

10See that you do not look down on any of these little ones. For I tell you that their angels in heaven always see the face of My Father in heaven.1

12What do you think? If a man has a hundred sheep and one of them goes astray, will he not leave the ninety-nine on the hills and go out to search for the one that is lost? 13And if he finds it, truly I tell you, he rejoices more over that one sheep than over the ninety-nine that did not go astray.
