Luke 15:6-7, 9-10

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.

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].”
