In this Sunday's Gospel two people are contrasted. One is full of gratitude that is extravagantly expressed. The other is by outward appearances living a good life. He is likely a pillar of the local community who has Jesus over for a meal. He is not an evil person. He seems like an ordinary kind of guy. Not mean, a bit of a skeptic towards Jesus, but not a bad person. Just not forgiven. Ouch.
Gratitude is the response to forgiveness and leads to loving behaviors.
