The Thirteenth Revelation, Chapter 39
Context: Our courteous Lord willeth not that His servants despair, for often nor for grievous falling: for our falling hindereth not Him to love us. Peace and love are ever in us, being and working; but we be not alway in peace and in love. But He willeth that we take heed thus that He is Ground of all our whole life in love; and furthermore that He is our everlasting Keeper and mightily defendeth us against our enemies, that be full fell and fierce upon us; — and so much our need is the more for we give them occasion by our falling.

Misattributed to Confucius since at least 1985; correct origins are dubious, as mentioned in "Choose a Job You Love, and You Will Never Have To Work a Day in Your Life" at QuoteInvestigator.com (2 September 2014) http://quoteinvestigator.com/2014/09/02/job-love/: the oldest English-language use of the proverb has been found in Woolfolk, Ann, "Toshiko Takaezu," Princeton Alumni Weekly, Vol. 83(5), 6 October 1982, p. 32: "Find something you love to do and you’ll never have to work a day in your life." (attributed to Arthur Szathmary, who attributes it, in his turn, to an unnamed source).
