As far as sacred Scripture is concerned, however much froward men try to gnaw at it, nevertheless it clearly is crammed with thoughts that could not be humanly conceived. Let each of the prophets be looked into: none will be found who does not far exceed human measure. Consequently, those for whom prophetic doctrine is tasteless ought to be thought of as lacking taste buds.
John CalvinWe say, then, that Scripture clearly proves this much, that God by his eternal and immutable counsel determined once for all those whom it was his pleasure one day to admit to salvation, and those whom, on the other hand, it was his pleasure to doom to destruction. We maintain that this counsel, as regards the elect, is founded on his free mercy, without any respect to human worth, while those whom he dooms to destruction are excluded from access to life by a just and blameless, but at the same time incomprehensible judgment
