We tend to ascribe to God things God really has nothing to do with. That son could have done an honorable thing: pay back his squandered money, ask his father for forgiveness and throw a party for his father and his brother. I am sure God would not have been 'offended.'
Do you think God was offended as it was ?
Do you not think that He presented the parable in the way that He wished ?
God is not offended either way, for that would make Him subject to passions.
Do you not think that He presented the parable in the way that He wished ?
Maybe as a minimalist approach.
