And when the hourglass has run out, the hourglass of temporality, when the noise of secular life has grown silent and its restless or ineffectual activism has come to an end, when everything around you is still, as it is in eternity, then eternity asks you and every individual in these millions and millions about only one thing: whether you have lived in despair or not.

Certainty... lurks at the door of faith and threatens to devour it.

God creates out of nothing. Wonderful you say. Yes, to be sure, but he does what is still more wonderful: he makes saints out of sinners.
