Do not refuse to regain your youth

"A man grows old; he is full of complaints. The world is old; it is full of pressing tribulations. . . . Do not hold onto the old man, the world; do not refuse to regain your youth in Christ, who says to you, 'The world is passing away, the world is losing its grip, the world is short of breath. Do not fear. Thy youth shall be renewed as an eagle.'"
-Saint Augustine
