If the attainment of true contentment were as easy as keeping quiet outwardly, it would not need much learning. It might be had with less strength and skill than an Apostle possessed, yea, less than an ordinary Christian has or may have. Therefore, there is certainly more to it than can be attained by common gifts and the ordinary power of reason, which often bridle nature. It is a business of the heart. ~ The Rare Jewel of Christian Contentment by Jeremiah Burroughs
