These parables collectively emphasize God's love for those who are lost or have strayed, the importance of repentance, and the joy in heaven when a sinner turns back to God.
The Parable of the Prodigal Son (Luke 15:11-32): Jesus narrates the well-known story of a younger son who asks his father for his share of the inheritance and then squanders it in reckless living. When the son realizes his mistake, he decides to return to his father, who welcomes him with open arms and celebrates his return with a feast. The elder son, who stayed with the father, becomes resentful, but the father urges him to rejoice because the lost son has come home. This parable underscores God's unconditional love and forgiveness for repentant sinners and also addresses the need for believers to avoid self-righteousness.
