“Which one of you, if he has a hundred sheep and loses one of them, would not leave the ninety-nine in the open pasture and go look for the one that is lost until he finds it?
Then when he has found it, he places it on his shoulders, rejoicing.
Returning home, he calls together his friends and neighbours, telling them, ‘Rejoice with me, because I have found my sheep that was lost.’
I tell you, in the same way there will be more joy in heaven over one sinner who repents [turns to God] than over ninety-nine righteous people who have no need to repent.” Luke 15:3-7
