Unfortunately the rationalization that these extremist Calvinist make remind me of the same type of circular reasoning used by Mormons in their attempt to defend an indefensible position. Rather than being so hung up on what John Calvin wrote and what Calvinists think he meant, it is much better to go straight to the Bible and simply read the clear meaning of the words.
These extreme Calvinists seem to be more interested in defending one man's interpretation of salvation than they are in simply speading the Gospel.
I would also like to hear a Calvinist reconcile the parable of the sowing of the seed with predestination. Not one has ever done it and made sense with their explanation.
