I like what Calvin says in his discussion on free will (Inst. II.2.8-11), “whoever is utterly cast down and overwhelmed by the awareness of his calamity, poverty, nakedness, and disgrace has thus advanced farthest in knowledge of himself. For there is no danger of man’s depriving himself of too much so long as he learns that in God must be recouped what he himself lacks. Yet he cannot claim for himself ever so little beyond what is rightfully his without losing himself in vain confidence and without usurping God’s honor, and thus becoming guilty of monstrous sacrilege.”

And is is always good to remind ourselves of 1 Cor. 4:7, “…what do you have that you did not receive? If then, you received it, why do you boast as if you did not receive it?”
