Matthew 18:10-14 (NKJV)
10“Take heed that you do not despise one of these little ones, for I say to you that in heaven their angels always see the face of My Father who is in heaven. 11For the Son of Man has come to save that which was lost.
12“What do you think? If a man has a hundred sheep, and one of them goes astray, does he not leave the ninety-nine and go to the mountains to seek the one that is straying? 13And if he should find it, assuredly, I say to you, he rejoices more over that sheep than over the ninety-nine that did not go astray. 14Even so it is not the will of your Father who is in heaven that one of these little ones should perish.
