Hypocrisy can plunge the mind of a man into a dark abyss, when he believes his own self-flattery instead of God's verdict.
John CalvinLet this point therefore stand: that those whom the Holy Spirit has inwardly taught truly rest upon Scripture, and that Scripture itself is self-authenticated. . . . Therefore, illumined by his power, we believe neither by our own nor by any one else's judgment that Scripture is from God; but above human judgment we affirm with utter certainty (just as if we were gazing upon the majesty of God himself) that it has flowed to us from the very mouth of God by the ministry of men.
John CalvinWhen a certain shameless fellow mockingly asked a pious old man what God had done before the creation of the world the latter aptly countered that he had been building hell for the curious.
