Mt 18:12-14

Jesus said to his disciples:
"What is your opinion?
If a man has a hundred sheep and one of them goes astray,
will he not leave the ninety-nine in the hills
and go in search of the stray?
And if he finds it, amen, I say to you, he rejoices more over it
than over the ninety-nine that did not stray.
In just the same way, it is not the will of your heavenly Father
that one of these little ones be lost."
