In the parable of the lost sheep, the shepherd goes out to search for one sheep,—the very least that can be numbered. Discovering that one of his sheep is missing, he does not look carelessly upon the flock that is safely housed, and say, “I have ninety and nine, and it will cost me too much trouble to go in search of the straying one. Let him come back, and I will open the door of the sheepfold and let him in. No; no sooner does the sheep go astray than the shepherd is filled with grief and anxiety.” Leaving the ninety and nine in the fold, he goes in search of the straying one. However dark and tempestuous the night, however perilous and uncertain the way, however long and tedious the search, he does not falter until the lost is found.
