"What think you? If a man have an hundred sheep, and one of them should go astray: doth he not leave the ninety-nine in the mountains, and go to seek that which is gone astray? And if it so be that he find it: Amen I say to you, he rejoiceth more for that, than for the ninety-nine that went not astray. Even so it is not the will of your Father, who is in heaven, that one of these little ones should perish."
(Matt. 18:12-14)
