Luke 15:3-7 (New King James Version)

³ So He spoke this parable to them, saying:
⁴ “What man of you, having a hundred sheep, if he loses one of them, does not leave the ninety-nine in the wilderness, and go after the one which is lost until he finds it? ⁵ And when he has found it, he lays it on his shoulders, rejoicing. ⁶ And when he comes home, he calls 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 there will be more joy in heaven over one sinner who repents than over ninety-nine just persons who need no repentance.
