"There is but a little thing (like a grain of mustard-seed), a weak thing, a foolish thing, even that which is not (to man’s eye), to overcome all this; and yet in this is the power. And here is the great deceit of man; he looks for a great, manifest power in or upon him to begin with, and doth not see how the power is in the little weak stirrings of life in the heart…"

-- Isaac Penington, 17th century Quaker
