You have not put too fine a point on it. That is exactly what wondrousa 'predestination' teaches.
You will hear a lot of attempted line-drawing between 'ordination' and 'decrees' and 'willing', but if every jot and tittle is dictated by the construct god, then all the evil in the world -- including the deaths of those two precious little girls -- is also directly from the construct god. You have cut through the fog and pinned the tail of evil directly on the construct god.
It must give you alot of comfort that all this happened because God was not interested in the life of those little girls at all...it was just one of those things..no reason ,no purpose..a disinterested god just didn't care at all so he offered thme no protection . .some god you got huh?
Baahaahaahaa! LOL!
What you neglect to mention is the fact that your non-Calvinist "construct god" sits back helpless as evil humans perform wicked acts against defenseless children. I can see what you think your god is saying to these two: "I really wanted to help you, since I love you so much, but I couldn't interfere with the free-will choices of your murderer. If he had just chosen differently, then you two would still be alive today. Sorry I couldn't be any more help."
Your non-Calvinist "construct god" is impotent and ignorant. A far cry from the omnipotent and omniscient Creator of the universe.
