"...So it is in a man's spirit, you shall have many that have weak spirits, and if they have ill fumes, if accidents befall them, you shall presently have them out of temper, but you shall have other men, that though things do fume up, yet still they keep in a steadie way, and have the use of reason and of other graces, and possess their souls with patience. As I remember , it's reported of the eagle, it's not like other fowls, other fowls when they are hungry make noise, but the eagle is never heard to make a noise though it wants food, and it's from the magnitude of his spirit, that it will not make such complaints as other fowls will do when they want food, it is, because it is above hunger, and above thirst: so it is an argument of a gracious magnitude of spirit, that whatsoever befalls it, yet it is not always whining and complaining so as others are, but goes on still in its way and course, and blesses God, and keeps in a constant renour whatsoever things befalls it..."
