As you tend to do, Shawn, you mix in some truth with error - taking Jesus’ parables in directions which they do not go; making them bear loads they were not intended to bear.
No – the prodigal son in Jesus’ parable is not Lucifer. In fact that isn’t even what that story is about.
And “paying back the very last farthing” is not what the “person at the altar” parable is about either - but a concluding afterthought tacked on at the end of a story. That story is about the high priority that reconciliation has in God’s Kingdom. Trying to pretend that the parables are secret codes to be deciphered for all sorts of collateral information does nothing more than do violence to the scriptures. Here you might have some scriptures in favor of something like you say [making right our past wrongs] - but this parable is not one of those. The Bible has a lot more about the unabashed forgiveness of debt [meaning total cancellation] than it does about the obsession on making sure we will give recompense to the last farthing. Deferred
vengeance [repayment] and forgiveness are not the same thing. At all.
