Gregory the Great

For "night" is this present life, and as long as we are in it, we are covered with a mist of uncertain imaginations as far as the sight of inward objects is concerned. For the prophet was sensible that he was held by a certain mist in his sight of the Lord, when he says, "My soul longed for you in the night." As if he were to say, I long to behold you in the obscurity of this present life, but I am still surrounded by the mist of infirmity.
