"Your predestination depends on the will of God and your will"
I think we can get some light on this from that great philosopher Dr. Friedrich von Frankenstein. One of his greatest quotes was "Hearts and kidneys are tinkertoys! I'm talking about the central nervous system".
Now if we apply this to the proposition before us we get, "Your predestination depends on the will of God", "your will is a tinkertoy (in comparison), I'm talking about predestination".
That should just about do it.
That's, Fronkensteen!
