“Doubt swells and surges, with swelling doubt behind! My soul in storm is but a tattered sail, Streaming its ribbons on the torrent gale; In calm, 'tis but a limp and flapping thing: Oh! swell it with thy breath; make it a wing, To sweep through thee the ocean, with thee the wind Nor rest until in thee its haven it shall find." ― George MacDonald, The Diary of An Old Soul
