In the material world, a foot is one thing, a ladder is another and wings still another. In the interior world, however, feet, ladders, and wings are the affections of a good will, with them, we walk, we climb, and we fly.
(En. in ps. 38, 2)
The majesty of God surpasses by far our capacity for expression, because it is better to think of God than to talk of Him, and better is He still than what is thought.
(De Trinitate VII, 4,7)
The absence of the Lord is not an absence. Just believe, and the one who you do not see is with you.
