“Begin with thanking Him for some little thing, and then go on, day by day, adding to your subjects of [thanksgiving]; thus . . . will your subjects of murmuring and complaining diminish, until you see in everything some cause for thanksgiving.” Priscilla Maurice
“I have learned to be content whatever my circumstances. . . .” Philippians 4:11
