You have done what your nature required. Do you need to be rewarded for it? The eye doesn't ask for payment when it sees. The feet don't demand satisfaction when they walk. These parts were made by nature for their purpose. They can ask for nothing more than to work as they were designed. So it is with people. We were born to do good for others. When you help someone out of error, or even with everyday things like money, health, or advancement, you are doing what you were made to do. You can ask for nothing more.
What thy nature required, that hast thou done. Must thou be rewarded for it? As if either the eye for that it seeth, or the feet that they go, should require satisfaction. For as these being by nature appointed for such an use, can challenge no more, than that they may work according to their natural constitution: so man being born to do good unto others whensoever he doth a real good unto any by helping them out of error; or though but in middle things, as in matter of wealth, life, preferment, and the like, doth help to further their desires he doth that for which he was made, and therefore can require no more.
