Matthew 18:11-13

11For the Son of man has come to save that which was lost.

12What think ye? If a certain man should have a hundred sheep, and one of them be gone astray, does he not, leaving the ninety and nine on the mountains, go and seek the one that has gone astray?

13And if it should come to pass that he find it, verily I say unto you, he rejoices more because of it than because of the ninety and nine not gone astray.
