5. All who have willingly left the things of the world, have certainly done so either for the sake of the future Kingdom, or because of the multitude of their sins, or for love of God. If they were not moved by any of these reasons their withdrawal from the world was unreasonable. But God who sets our contests waits to see what the end of our course will be.
(St. John Climacus, The Ladder of Divine Ascent, Step 1 On renunciation of the world)
