The way for a Christian to be contented is not by raising his estate higher, but by bringing his spirit lower; not by making his barns wider, but his heart narrower. One man, a whole lordship or manor will not content him; another is satisfied with a few acres of land. What is the difference? The one studies to satisfy curiosity, the other necessity. The one thinks what he may have; the other thinks what he may spare.
A Christian of a right temper should be ever cheerful in God: "Serve the Lord with gladness" (Ps. 100:2). A sign the oil of grace hath been poured into the heart is when the oil of gladness shines in the countenance. Cheerfulness credits religion. How can the discontented person be cheerful? Discontent is a dogged sullen humor; because we have not what we desire, God shall not have a good word or look from us.Primitive Divinity, 125
