Luke 15:4-7

4 What man of you having a hundred sheep, if he loseth one of them, doth not leave the ninety and nine in the wilderness, and go after that which is lost, until he findeth it?

5 And when he hath found [it], he layeth [it] on his shoulders, rejoicing.

6 And when he cometh home, he calleth together [his] friends and neighbors, saying to them, Rejoice with me; for I have found my sheep which was lost.

7 I say to you, that likewise joy shall be in heaven over one sinner that repenteth, more than over ninety and nine just persons, who need no repentance.
