Matthew 18:12-14 - The Lost Sheep
12 What think you? If a man owns a hundred sheep, and one of them strays, will he not leave the ninety-nine on the hills, and go and search for the one that is straying? 13 And, if he succeeds in finding it, I tell you that he rejoices more over that one sheep than over the ninety-nine which did not stray. 14 So, too, it is the will of my Father who is in Heaven that not one of these lowly ones should be lost.
