Everything outside of us fluctuates with the storms and temptations of this age. But we need an interior desert where we gather ourselves and live of our faith.
Past and present I find in all movement of things; but it is not so in the Truth that remains forever; I only find the present in her, and this is incorruptible; this cannot be said of creatures.
(In Io. Ev. XXXVIII, 10)
From infancy to old age, each age in all men has its own special beauty.
(De div. quaest. LXXXIII q.44)
