"Though he be contented with God in a little, yet those things that would content other men, will not content him: The men of the world they seek after estates, and think if they had thus much, and thus much, they would be content, they aim at no great matters; but if I had (perhaps some man thinks) but two or three hundred a year, then I should be well enough, if I had but five hundred a year, or a thousand a year (faith another) then I should be satisfied: but faith a gracious heart, if he had ten hundred thousand times so much a year, it would not satisfy him; if he had the quintessence of all the excellencies of all the creatures in the World, it could not satisfy him; and yet this man can sing, and be merry, and joyful when he hath but a crust of bread, and a little water in the world. Surely Religion is a great mystery, great is the mystery of Godliness, not only in the Doctrinal part of it, but in the Practical part of it also."
