1. In Calvinism, the born again elect cannot fall short of salvation on Judgment Day. Hence, to warn the elect that they will fall short of salvation and end up in hell if they do not obey God is for God to lie to them because in Calvinism this cannot happen. 2. In Calvinism, the non-elect will never be born again and cannot be saved on Judgment Day. Hence, to warn the non-elect is deceptive because they can neither be saved in the first place, nor are they even able, according to Calvinism, to discern this would otherwise be true in the first place. Indeed, this is deceptive since it exhorts people to be faithful to a result they will never receive. Just ask yourself these simple questions. Would God warn the elect that if they do not obey Him that they will burn in hell if He knows very well this is not true and cannot happen? Would God warn the non-elect that if they do not obey Him that they will burn in hell when He knows very well it is not true that they even can obey him and He will certainly let them know on judgment day they were always destined to hell? Who are God's warnings in the NT to?
