A Calvinist remarked, “ When you take your last breath, it ultimately comes down to whether God chose you; not that you chose Him.” That is certainly a comforting soteriology. In essence, you have no assurance of going to Heaven until you get to Heaven. The same ones arguing for such an existentialist eschatological fatalism would then turn around and heap the condemnation they are addicted to like a narcotic upon the medically terminal gripped by stark raving terror of the pending hellfire damnation.
