Spiritual contentment comes from the frame of the soul. The contentment of a man or woman who is rightly content does not come so much from outward arguments or from any outward help, as from the disposition of their own hearts. The disposition of their own hearts causes and brings forth this gracious contentment rather than any external thing.
Let me explain myself. Someone is disturbed, suppose it to be a child or a man or a woman. If you come and bring some great thing to please them, perhaps it will quiet them and they will be contented. It is the thing you bring that quiets them, not the disposition of their own spirits, not any good temper in their own hearts, but the external thing you bring them. But when a Christian is content in the right way, the quiet comes more from the temper and disposition of his own heart than from any external argument or from the possession of anything in the world. ~ The Rare Jewel of Christian Contentment by Jeremiah Burroughs
