1550 · John Calvin, Commentary on Titus 2.13
At the same time he declares when we shall enjoy it, and what we ought to contemplate, when we desire or think of our salvation. And the appearing of the glory of the great God and Savior I interpret the glory of God, to mean not only that by which he shall be glorious in himself, but also that by which he shall then diffuse himself on all sides, so as to make all his elect partakers of it. He calls God great, because his greatness — which men, blinded by the empty splendor of the world, now extenuate, and sometimes even annihilate, as far as lies in their power — shall be fully manifested on the last day. The luster of the world, while it appears great to our eyes, dazzles them so much that “the glory of God” is, as it were, hidden in darkness. But Christ, by his coming, shall chase away all the empty show of the world — shall no longer obscure the brightness, shall no longer lessen the magnificence, of his glory. True the Lord demonstrates his majesty every day by his works; but because men are prevented by their blindness from seeing it, it is said to be hidden in obscurity.
