Man, by Himself, Cannot Understand the Mysteries of God

Man with all his shrewdness is as stupid about understanding by himself the mysteries of God, as an ass is incapable of understanding musical harmony.

The Scriptures Could not be Humanly Conceived

“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.” ~ Institutes of the Christian Religion

Man’s Mind is Like a Store of Idolatry

Man’s mind is like a store of idolatry and superstition; so much so that if a man believes his own mind it is certain that he will forsake God and forge some idol in his own brain.

The Blindness of Men who Oppose God

“It is a horrible blindness, indeed, when a mortal man is not ashamed to oppose himself to God; but to such a pitch of madness does Satan carry those who set a higher value on their own ambition than on the truth of God. Meanwhile, it is our duty to cherish such a reverence for the word of God as shall extinguish all the splendour of the world, and scatter its vain pretensions; for miserable would be our condition, if our salvation depended on the will of princes, and far too unsteady would our faith be, if it were to stand or fall according to their pleasure.” ~ Commenting on John 7:48
