In the book of Luke, chapter 15, Jesus told three parables (or, stories with a purpose): The Parable of the Lost Sheep, The Parable of the Lost Coin, and the Parable of the Prodigal son. One of the many things these parables can teach us is how God views those who are lost. If a sheep wanders away from the flock, it is just as valued by the shepherd as those who didn't stray. We often look at "sinners" as being less important than "righteous people." But that's not how God views us. There's more rejoicing in heaven for one sinner who repents than for ninety-nine righteous people who have no need to repent. God is the Good Shepherd, and He will always go looking for the lost sheep.
