Matthew 18: 12-14
18:12 How does it seem to you? If someone has one hundred sheep, and if one of them has gone astray, should he not leave behind the ninety-nine in the mountains, and go out to seek what has gone astray?
18:13 And if he should happen to find it: Amen I say to you, that he has more joy over that one, than over the ninety-nine which did not go astray.
18:14 Even so, it is not the will before your Father, who is in heaven, that one of these little ones should be lost.
