Fourth Sunday in Lent

Is this a parable - or is it the real-life story of God and prodigal children? And if we're talking about the word prodigal (spending resources freely and recklessly; being wastefully extravagant) - is it the son or the Father who is more extravagant? One thing is certain from the text - whether we are the prodigal or the older, self-righteous, brother - God doesn't give up on us.
