As by the revolt of the first man, the image of God could be effaced from his mind and soul, so there is nothing strange in His shedding some rays of grace on the reprobate, and afterwards allowing these to be extinguished.
John CalvinSince no daily responses are given from heaven, and the Scriptures are the only record in which God has been pleased to consign His truth to perpetual remembrance, the full authority which they ought to possess with the faithful is not recognized unless they are believed to have come from heaven as directly as if God had been heard giving utterance to them.
John CalvinNo Task will be so sordid and base, provided you obey your calling in it, that it will not shine and be reckoned very precious in God's sight.
John Calvin
