The Confessions And Letters Of St by St. Augustine
Chapter VIII.--By God's Assistance He by Degrees Arrives at the Truth.
12. |But Thou, O Lord, shall endure for ever,| yet not for ever art Thou angry with us, because Thou dost commiserate our dust and ashes; and it was pleasing in Thy sight to reform my deformity, and by inward stings didst Thou disturb me, that I should be dissatisfied until Thou wert made sure to my inward sight. And by the secret hand of Thy remedy was my swelling lessened, and the disordered and darkened eyesight of my mind, by the sharp anointings of healthful sorrows, was from day to day made whole.
