Luke 15:4-7

4“1What man among you, if he has a hundred sheep and has lost one of them, does not leave the ninety-nine in the 2open pasture and go after the one which is lost until he finds it? 5When he has found it, he lays it on his shoulders, rejoicing. 6And when he comes home, he calls together his friends and his neighbors, saying to them, ‘Rejoice with me, for I have found my sheep which was lost!’ 7I tell you that in the same way, there will be more joy in heaven over one sinner who repents than over ninety-nine righteous persons who need no repentance.
