What does the Bible say about the parable of the prodigal son?

In Luke 15:11-32, the parable of the prodigal son depicts a father with two sons, one who squanders his inheritance but later repents and returns home. This story reveals the character of God as a compassionate Father who eagerly welcomes back the repentant sinner. It illustrates not only the extravagance of grace offered to those who have strayed but also serves as a critique against self-righteousness, represented by the elder brother's anger at his father's mercy toward the wayward son.
