One of my favorite theologians, Robert Capon, suggests that the best name for the Parable we are studying would be “The Man Who Had Two Sons.”
That’s how Jesus introduces it in any case.
And isn’t that what its about? A father with two sons, who is dead set on throwing a party for them.
He isn’t given many lines but the ones he has, whether to the servants or the younger or older son, are all about celebrations and how his kids should definitely be there.
He doesn’t first demand an apology from the younger, and he’s confused by the older son choosing to stay outside. He just wants to celebrate with them.
God loves us, his children.
We just need to get over our sin, which is paid for, or our obedience, which is worthless, and join His feast.
