We heard last week that believers have a position in the kingdom of heaven like that of beloved "little ones". With the image of believers as children in mind and a desire to guard them, Jesus addresses the most significant threat his children face: the threat of sin. Jesus warns those who would lead believers to stumble, and he warns believers themselves of the severe seriousness of participating in sin. To sin is to wander away from God, like a sheep going astray, or as we see in our passage this week, a brother or sister leaving the family. So, what happens when a "little one", a sheep, a brother or sister sins? Are they lost, doomed to wander? This week, we see Jesus's heart forgive sin and reconcile the wandering family—the same heart he would see family have for one another.
