Luke 15:11-32 tells the well known story of the prodigal son. While there are three main characters in the story, the two sons and the Father, could we say evangelistically the story is about the Father’s perspective to the sons.
Perhaps as Jesus told the story the people hearing Him would identify with one of the two sons. But what would they actually want to know? Their question would be i they were either son what would the Father’s response be to them?
Hence as you look at the Father’s response to both sons it was one of grace. Grace applied in two different scenarios but grace nonetheless.
Why is it important to see the Father’s grace? Because it was His grace that was applied to Adam and Eve after they sinned that brought reconciliation and every sinner ever reconciled to the the Father has been reconciled by His grace. There is no other way.
Thus the story of the prodigal son brings hope to either son that they can always be reconciled to the Father by His grace and that they exist in His presence by His grace.
