Matthew 18:12-14 - The Lost Sheep
12 What do you think? If a man had a hundred sheep and one of them went astray, would he not leave the ninety-nine and go into the mountains and seek that which is gone astray? 13 And if so be that he finds it, verily I say unto you, he rejoices more of that one than of the ninety-nine who did not go astray. 14 Even so it is not the will of your Father who is in the heavens that one of these little ones should perish.
