This document summarizes Luke 15:1-10, which contains two parables told by Jesus - the Parable of the Lost Sheep and the Parable of the Lost Coin. It describes how tax collectors and sinners gathered around Jesus, while Pharisees and teachers of the law muttered complaints. Jesus told these parables to illustrate that there is more joy in heaven over one sinner who repents compared to ninety-nine righteous people who need no repentance. Both parables depict a search for something lost and the finding of it, followed by celebration.
