Luke 15:3-7

So Jesus told them this story as an illustration. “Imagine a man who had a hundred sheep lost one of them. Wouldn't he leave the ninety-nine in the open pasture, and search for the one that's lost until he finds it? When he finds it, he joyfully puts it on his shoulders. Once he gets home, he calls his friends and neighbors together, saying, ‘Come and celebrate with me! I've found my lost sheep!’ I tell you that there's more joy in heaven over a sinner that repents than over ninety-nine good people who don't need to repent.
