Thematic Bible: The lost sheep

Then spake he unto them this parable, saying, What man is there of you, possessing an hundred sheep, though he lose but one of them, will he not leave the ninety-nine in the wilderness, and go after that which is lost, until he find it? and when he hath found it, he layeth it on his shoulders, rejoicing. read more.
And coming home, he calleth together his friends and neighbours, saying unto them, Congratulate me; for I have found that sheep of mine which was lost. I tell you, that just so will there be joy in heaven over one repentant sinner, more than over ninety-nine righteous persons, who hold not their need of repentance.

What think you? If a man have an hundred sheep, and one of them stray, doth he not leave the ninety and nine in the mountains, and go and seek that which had strayed? And if he happen to find it, verily I say unto you, that he rejoiceth over it more than over the ninety and nine which never went astray. Even so it is not the will of your Father who is in heaven, that one of these little ones perish.
