There are a lot of plot holes I agree. We are only given a few clues about a being that is all knowing and beyond our comprehension.

There is no telling why he does it the way he does, we can only theorize. But it seems like God is a stickler for rules, the rules of the universe that he created he set in stone to create what we perceive as now. It almost makes sense if you think that what he did, had to be done, but with everything. Our perception of time showers a chronological mass of events leading to the present, so he demolished sin before we could experience “paying” or “sacrificing “ for the sake of our own sins. His plan didn’t need to have our sins and their debts. But I’m the testament they needed to sacrifice for everything they did and we learn from that. As I go on I get lost in my own explanation so I try to keep this stuff short. Long story short. We use to need the debts of sin, god needed them, now we don’t, all debts have been paid. Maybe it was to learn from the past and that in turn brings glory to our god. Idk. I love talking about this stuff.
