In Luke 15:1-7, Jesus tells a parable about a shepherd who has one hundred sheep. When one sheep goes missing, the shepherd leaves the ninety-nine to search for the lost one. This story illustrates the importance of every individual and the lengths one will go to for their well-being. When the shepherd finds the lost sheep, he rejoices and carries it home on his shoulders. Jesus explains that there is great joy in heaven over one sinner who repents, highlighting the value of redemption and the joy of recovery in the eyes of God.
