Matt 18:12-14

12What do you think? If a shepherd has a hundred sheep, and one of them has gone astray, does he not leave the ninety-nine on the mountains and go in search of the one that went astray?13And if he finds it, truly I tell you, he rejoices over it more than over the ninety-nine that never went astray.14So it is not the will of your Father in heaven that one of these little ones should be lost.
