"The world is infinitely deceived in this, to think that contentment lies in having more than they have; here lies the bottom and root of all contentment, when there is an evenness and proportion between our hearts and our conditions; and that is the reason that many, that are godly men that in a low condition, live more sweet and comfortable lives than those that are richer: contentment is not always clothed with silk, and purple, and velvets, but contentment is sometimes in a russet suit, in a mean condition as well as in a higher; and many men that sometimes have had great estates, and God hath brought them into a lower condition, they have had more contentment in that condition than the other: Now how can that possible be? Thus easily, for if you did but understand the root of contentment, it consists in the suitableness and proportion of the spirit of man to his estate, and the evenness, when one end is not longer and bigger than another, the heart is contented, there is comfort in that condition; now let God give a man never so great riches, yet if the Lord gives him up to the pride of his heart, he will never be contented: But now, let God bring anyone into a mean condition, and then let God but fashion and suit his heart to that condition and he will be content."
