Thematic Bible: From finding the lost sheep

And when he gets home, he summons together [his] friends and [his] neighbors, saying to them, Rejoice with me, because I have found my sheep which was lost. Thus, I tell you, there will be more joy in heaven over one [ especially] wicked person who repents ( changes his mind, abhorring his errors and misdeeds, and determines to enter upon a better course of life) than over ninety-nine righteous persons who have no need of repentance.
