George Macdonald said this quote

She could now be sad without losing a jot of hope. Nay, rather, the least approach of sadness would begin at once to wake her hope. She regretted nothing that had come, nothing that had gone. She believed more and more that not anything worth having is ever lost; that even the most evanescent shades of feeling are safe for those who grow after their true nature, toward that for which they were made—in other and higher words, after the will of God.
