If what you interpret Paul as saying is that before creating all the myriad galaxies and star systems God decided that They would put some humans on the third planet from an insignificant star on a little arm
of a middling galaxy and that the first hominids
chosen role would be to perform pretty much to spec and do something silly and rebellious (arguably without sufficient information as to consequences for themselves and their off spring, oh, and for serpents) and cause affront to the tripartite godhead warranting separation
of Gods grace from all their offspring; then we are left with people being
chosen from way back before the Big Bang to do some
terrible things like killing babies or betraying Jesus who was
chosen on the same non date (
time didn't exist before creation) to die in a fairly nasty fashion and thereby appease the righteous wrath
of himself and his fellow Trinitarians by paying a penalty as a substitute for all future sins (
of believers?)
