The Fundamental Mystery of Predestination

There really aren't that many different theological doctrines or systems regarding how grace and predestination work with human freedom. Neither Molinism nor Bonyesianism is at root capable of giving a full flowchart explaining why God chooses to do what he does. The real difference between these positions I think is how is it that God saves those who are saved? How is it that grace works on the soul without it infringing upon human freedom? So that's where the differences lie but yeah there are overlaps rightthese are not just the antithesis of each other.
