To be content as a result of some external thing is like warming a man’s clothes by the fire. But to be content through an inward disposition of the soul is like the warmth that a man’s clothes have from the natural heat of the body. A man who is healthy in body puts on his clothes, and perhaps at first on a cold morning they feel cold. But after he has had them on a little while they are warm. Now, how did they get warm? They were not near the fire? No, this came from the natural heat of his body. Now when a sickly man, the natural heat of whose body has deteriorated, puts on his clothes, they do not get hot after a long time. He must warm them by the fire, and even then they will soon be cold again. ~ The Rare Jewel of Christian Contentment by Jeremiah Burroughs
