A billion quadrillion dollars, that is how much the first guy owed the king. More than could ever be paid, but he thinks that he is good for it. He is sure that he could pay it back. So when his debt is released he doesn’t see it as grace, but as something he deserved; or perhaps he believed that he pulled one over on the king. And that is why he goes out in search for his own retribution. Debts must be paid, just not his. But this isn’t how forgiveness works. In fact, this isn’t forgiveness at all. This parable is about the Gospel and the debt Jesus paid on the cross. But it is also a warning lest we think that we deserved any of it.
