The soul is weak and helpless unless it clings to the firm rock of truth. Men give voice to their opinions, but they are only opinions, like so many puffs of wind that waft the soul hither and thither and make it veer and turn. The light is clouded over and the truth cannot be seen, although it is there before our eyes.
-- St. Augustine, Confessions, Book IV, ch. 14.
Let the ears of my heart move close to your lips, and let me listen to you, who are the Truth . . . You are steadfast, constant in yourself; but we are tossed on a tide that puts us to the proof, and if we could not sob our troubles in your ear, what hope should we have left to us?
-- St. Augustine, Confessions, Book IV, ch. 5.
Make your dwelling in Him, my soul. Entrust to Him whatever you have, for all that you have is from Him. Now, at last, tired of being misled, entrust to the Truth all that the Truth has give to you and nothing will be lost. All that is withered in you will be made to thrive again. All your sickness will be healed. Your mortal body will be refashioned and renewed and firmly bound to you, and when it dies, it will not drag you with it to the grave, but will endure and abide with you before God, who abides and endures forever.
-- St. Augustine, Confessions, Book IV, ch. 11.
