John Calvin
Let us remember that that invisible God, whose wisdom, power, and justice, are incomprehensible, is set before us in the history of Moses as in a mirror, in which his living image is reflected. For as an eye, either dimmed by age or weakened by any other cause, sees nothing distinctly without the aid of glasses, so (such is our imbecility) if Scripture does not direct us in our inquiries after God, we immediately turn vain in our imaginations. Those who now indulge their petulance, and refuse to take warning, will learn, when too late, how much better it had been reverently to regard the secret counsels of God, than to belch forth blasphemies which pollute the face of heaven.
Justly does Augustine complain that God is insulted whenever any higher reason than his will is demanded. (Lib. de Gent.). He also in another place wisely reminds us that it is just as improper to raise questions about infinite periods of time as about infinite space. (De Civit. Dei.). However wide the circuit of the heavens may be, it is of some definite extent. But should any one expostulate with God that vacant space remains exceeding creation by a hundred-fold, must not every pious mind detest the presumption? Similar is the madness of those who charge God with idleness in not having pleased them by creating the world countless ages sooner than he did create it.
In their cupidity they affect to go beyond the world, as if the ample circumference of heaven and earth did not contain objects numerous and resplendent enough to absorb all our senses; as if, in the period of six thousand years, God had not furnished facts enough to exercise our minds in ceaseless meditation. Therefore, let us willingly remain hedged in by those boundaries within which God has been pleased to confine our persons, and, as it were, enclose our minds, so as to prevent them from losing themselves by wandering unrestrained.
