Matthew 18:12-14 - The Lost Sheep
12 What would you say now? if a man has a hundred sheep, and one of them has gone wandering away, will he not let the ninety-nine be, and go to the mountains in search of the wandering one? 13 And if he comes across it, truly I say to you, he has more joy over it than over the ninety-nine which have not gone out of the way. 14 Even so it is not the pleasure of your Father in heaven for one of these little ones to come to destruction.
