I would purport that it was not the prodigal son’s request to obtain his inheritance early OR even that he squandered it all. Rather it was that upon receiving his inheritance, the younger son went far away from his father’s house to live for himself; and by doing so, he effectively severed all relationship with his father. Therefore we see that the true sin of the prodigal son was that he quantified his sonship in terms of the sum of money to which he was entitled by birthright and failed to recognize the true value of his sonship – the relationship with his father.
