Ok, educate a non-Calvinist. Does God predestine everything? If He does ordain whatsoever comes to pass, then there is no actual permissive will, only God allowing what He has predestined. Calvinism, as presented on this board, is a logical impossiblity. Now Boettner's clear-cut presentation is not, God has total omniscience, which presupposes everything is predestined. Thus God is the author of sin and a monster, according to Calvinism, because He punishes people for His predestined acts of sin.
"Anyone who disagrees proves they do not understand Calvinism." (Using arguments like that add heat and sidetrack threads into bickering, the goal of those opposed to truth.)
