Active and contemplative…

Now we are conscious of two powers in the human soul: the active and the contemplative; the former maps the way, the latter marks the journey’s end; in the former we toil so that our hearts may be purified for the vision of God, in the latter we are at rest and see God; the former calls for the practice of the commandments of this life that passes away, in the latter we drink in the teachings of the life that shall never pass away.
–Saint Augustine (354-430)

Without temptation…

There is no man who will not be grieved at the time of his chastisement; and there is no man who will not endure a bitter time, when he must drink the poison of temptations. Without them, it is not possible to obtain a strong will. When he has often experienced the help of God in temptations, a man also obtains strong faith.
–Saint Isaac of Syria (Seventh Century)
