Luke 15:3-10, 32

So He told them this parable: “What man among you, if he has a hundred sheep and loses one of them, does not leave the ninety-nine in the wilderness and go after the one which is lost, [searching] until he finds it? [Matt 18:12-14] And when he has found it, he lays it on his shoulders, rejoicing. And when he gets home, he calls together his friends and his neighbors, saying to them, ‘Rejoice with me, because I have found my lost sheep!’ I tell you, in the same way there will be more joy in heaven over one sinner who repents than over ninety-nine righteous people who have no need of repentance. “Or what woman, if she has ten silver coins [each one equal to a day’s wages] and loses one coin, does not light a lamp and sweep the house and search carefully until she finds it? And when she has found it, she calls together her [women] friends and neighbors, saying, ‘Rejoice with me, because I found the lost coin!’ In the same way, I tell you, there is joy in the presence of the angels of God over one sinner who repents [that is, changes his inner self—his old way of thinking, regrets past sins, lives his life in a way that proves repentance; and seeks God’s purpose for his life].”

But it was fitting to celebrate and rejoice, for this brother of yours was [as good as] dead and has begun to live. He was lost and has been found.’ ”
