The Art of Divine Contentment: An Exposition of Philippians 4:11 by Thomas Watson. Excerpt 16

If men are poor, they learn to be envious; they malign those that are above them. Another’s prosperity is an eye-sore. When God’s candle shines upon their neighbour’s tabernacle, this light offends them. In the midst of wants, men can, in this sense, abound, namely, in envy and malice; an envious eye is an evil eye. They learn to be querulous, still complaining, as if God had dealt hardly with them; they are ever telling their wants, they want this and that comfort, whereas their greatest want is a contented spirit. Those that are well enough content with their sin, yet are not content with their condition.

Thomas Watson lived from 1620-1686, in England. He wrote several books which survive. This blog, God willing, will post excerpts from his The Art of Divine Contentment: An Exposition of Philippians 4:11, over a number of weeks, on Sundays. My source for the text is here, and I thank the Christian Classics Ethereal Library for making this text (and many others) available. The previous excerpt is here.
