Question: Why is hope so sweet, her discipline and her labors so light, and her works so easy for the soul?
Answer: Because hope awakens a natural longing in the soul and gives men this cup to drink, straightway making them drunk. Thenceforth they no longer feel the wearisome toil, but become insensitive to afflictions, and throughout the whole course of their journey they think that they are walking on air, and not treading the path with human footsteps. . . . For this hope so inflames them, as with fire, that on account of their joy they cannot rest from their incessant and headlong course. There comes to pass in them what was spoken by the blessed Jeremiah, "I said, I shall not remember Him nor speak His name. And there was in my heart as it were a flaming fire and it entered into my bones". Such is the recollection of God in the hearts of men who are drunk with hope on his promises.
