Service to man is service to god.

Those who serve supreme causes must not consider what they can get but what they can give.

Everything that is not given is lost.

There can be no greater gift than that of giving one's time and energy to help others without expecting anything in return.

Give love, give help, give service, and give any little thing you can, but keep out barter.

As to pay, Sir, I beg leave to assure the Congress that as no pecuniary consideration could have tempted me to accept this arduous employment at the expense of my domestic ease and happiness, I do not wish to make any profit from it.
