What to Do When God Makes an End of Teaching

The subject of predestination, which in itself is attended by considerable difficulty, is rendered very perplexed, and hence perilous, by human curiosity, which cannot be restrained from wandering into forbidden paths... Those secrets of his will which he has seen fit to manifest are revealed in his word — revealed in so far as he knew to be conducive to our interest and welfare...  Let it, therefore, be our first principle that to desire any other knowledge of predestination than that which is expounded by the word of God, is no less infatuated than to walk where there is no path, or to seek light in darkness… The best rule of sobriety is, not only in learning to follow wherever God leads, but also when he makes an end of teaching to cease from wishing to be wise.

John Calvin (The Institutes of the Christian Religion, Vol. 2, chap. 21)
