Why not rest secure, if you believe it is God who predestined His Covenant people, the Sheep, either to be a Calvinist or to be opposed it? It could very easily be said that the..... 19 For there must be also heresies among you, that they which are approved may be made manifest among you ....is speaking of Calvinism heresies. Calvinism works against itself and is why it self implodes when studied out. When one works through it's determinism to it's final conclusions, one can see a meaningless life, void of real consequences for real life freewill choices, and as people (both lost and saved) being nothing more than puppets on a string totally controlled by a Great Puppet Master. Judgments are pointless if the subjects had no real choices in their decisions. The Calvinist must buy into the lie that we all have a choice, but we are all obligated to choose as God directs us to choose. That is NOT a choice. Common everyday applications of word meanings must be spun into this weave of error called Calvinism in order for it to be believed and accepted. I do not understand why a devoted bible student would allow themselves to be so manipulated as to find a need to reinterpret hundreds of passages in order to make a theology survive the text.
